Installing LibrAIry

OVERVIEW

LibrAIry is distributed as a standalone Windows executable that requires no Python installation or complex dependencies. The application includes all necessary libraries bundled within, making installation as simple as downloading and running a single file.

System Requirements

Before installing LibrAIry, ensure your Windows system meets these minimum requirements:

Operating System:

• Windows 10 (64-bit) or later
• Windows 11 fully supported

Hardware:

• RAM: 4 GB minimum (8 GB recommended for large libraries with 500+ papers)
• Disk Space: 200 MB for application + space for your PDF library
• Display: 1280x720 resolution minimum (1920x1080 recommended)
• Processor: Any modern 64-bit Intel or AMD processor

Optional Components (not required for installation, needed for specific features):

• Docker Desktop for Windows (for local Grobid metadata extraction)
• Internet connection (for cloud-based AI features via Google Gemini or cloud Grobid)

Installation Steps

Step 1: Download LibrAIry

• Download `LibrAIry.exe` from the official distribution source
• File size: approximately 150-200 MB
• Save to your Downloads folder or any location

Step 2: Choose Installation Location

LibrAIry is portable and runs from wherever you place it. Recommended locations:

• Recommended: `C:\Program Files\LibrAIry\`
• Create the folder if it doesn't exist
• Provides organized, standard location
• May require administrator permission to copy

• Alternative: `C:\Users\YourName\Documents\LibrAIry\`
• No administrator permission needed
• Easy access from user folder

• USB Drive: Any removable drive
• Fully portable—run from different computers
• Bring your research tools anywhere

To install:

1. Create your chosen folder (e.g., `C:\Program Files\LibrAIry\`)
2. Copy or move `LibrAIry.exe` into this folder
3. That's it—installation complete!

Step 3: First Launch

1. Navigate to the folder containing `LibrAIry.exe`
2. Double-click `LibrAIry.exe`

Important: Windows Defender SmartScreen will likely display a warning:

```

Windows protected your PC

Microsoft Defender SmartScreen prevented an unrecognized app from starting.

Running this app might put your PC at risk.

```

This warning appears because LibrAIry is not Microsoft-signed (signing certificates cost thousands of dollars annually). This does NOT mean the application is dangerous—it's a standard warning for independently distributed software.

To bypass:

1. Click "More info" (small link on the warning dialog)
2. Click "Run anyway" button that appears
3. The application will launch

This warning only appears on first launch. Subsequent launches will open normally without warnings.

Step 4: Optional - Create Desktop Shortcut

For convenient access:

1. Right-click `LibrAIry.exe` in File Explorer
2. Select "Create shortcut"
3. Drag the shortcut to your Desktop
4. Rename if desired (e.g., "LibrAIry")

Alternatively, pin to Start Menu:

1. Right-click `LibrAIry.exe`
2. Select "Pin to Start"

What Happens On First Launch

When you run LibrAIry for the first time, several automatic setup steps occur:

1. Configuration Directory Created

LibrAIry creates a hidden configuration folder in your user directory:

• Location: `C:\Users\YourName\.librairy\`
• Contains: Settings, preferences, recent library paths
• Size: Less than 1 MB

This folder is created automatically with default settings. You don't need to configure anything manually.

2. License Check

Depending on your version:

• Trial Version:
• Automatically activates 14-day trial period
• No registration or email required
• Trial status displays in bottom-left status bar: "Trial: 14 days remaining"

• Licensed Version:
• Prompts for license key on first launch
• Enter your purchased license key
• Key is validated and stored locally
• Status bar shows: "Licensed" or license type

3. Default Settings Initialized

LibrAIry sets sensible defaults:

• Grobid: Not started (you'll configure later based on your preference)
• AI Service: Not configured (optional—only needed for Chat and Synthesis features)
• Full-text Extraction: Disabled (abstract-only mode is faster and works with all PDFs)
• Metadata Extraction: Ready to use once Grobid is configured

4. Welcome Interface

The main LibrAIry window opens showing:

• Empty library view (no papers loaded)
• Menu bar: File, View, Tools, Help
• Status bar: Version number, license status, library count (0 papers)
• Library panel: "No library loaded" message

You're ready to create your first library!

No Python Installation Required

LibrAIry is a completely self-contained Windows executable. You do NOT need to:

❌ Install Python

❌ Install pip packages (requests, BeautifulSoup, pypdf, etc.)

❌ Manage virtual environments

❌ Configure system PATH variables

❌ Install dependencies manually

❌ Run command-line setup scripts

✅ Everything is bundled within `LibrAIry.exe`:

• Python interpreter (embedded)
• All required Python libraries
• Application code and logic
• User interface assets
• Help documentation

Just double-click and run. That's it.

Portable Installation Benefits

LibrAIry's portable design means:

No System Modifications

• Zero registry entries created
• No system32 files modified
• No Windows services installed
• No startup programs added

Easy "Uninstallation"

To completely remove LibrAIry:

1. Delete `LibrAIry.exe` from its folder
2. Optionally delete `C:\Users\YourName\.librairy\` (configuration)
3. Your library folders and PDFs remain untouched

Multi-Computer Use

• Copy `LibrAIry.exe` to multiple computers
• Settings stored separately on each machine
• No licensing conflicts or activation limits

USB Drive Operation

• Copy `LibrAIry.exe` to USB drive
• Copy your library folder to same USB drive
• Run on any Windows computer
• Perfect for presentations, traveling, or shared computers

Firewall And Antivirus Considerations

Some antivirus software may flag LibrAIry because:

• It's a new executable (not widely distributed yet)
• It makes network connections (to Grobid, AI services)
• It's packaged with PyInstaller (common false positive trigger)

If Windows Defender or your antivirus blocks LibrAIry:

1. Verify Download Source
2. Ensure you downloaded from the official source
3. Check file size matches expected (~150-200 MB)

1. Add Antivirus Exception
2. Windows Defender: Settings → Virus & threat protection → Manage settings → Add exclusion
3. Select "File" and browse to `LibrAIry.exe`
4. This tells Defender to trust this specific file

1. Allow Network Access
2. Windows Firewall may prompt on first launch
3. Click "Allow access" when asked
4. Required for: Grobid communication, AI services

Network Ports Used:

• Port 8070: Grobid (local Docker container)
• Port 11434: Ollama (local AI, if installed)
• HTTPS/443: Google Gemini API, cloud Grobid (outbound only)

All network communication is initiated by LibrAIry (outbound). No incoming connections are accepted.

Updating Librairy

LibrAIry does not include automatic updates. To update to a new version:

Step 1: Download New Version

• Download the latest `LibrAIry.exe` (e.g., version 1.0.9)

Step 2: Replace Executable

• Navigate to your LibrAIry installation folder
• Option A: Delete old `LibrAIry.exe` and copy new one
• Option B: Rename old file to `LibrAIry_old.exe` (backup), then copy new file

Step 3: Launch New Version

• Double-click the new `LibrAIry.exe`
• Your settings automatically carry over (stored in `.librairy` folder)

What Gets Preserved:

✅ All settings and preferences

✅ Library paths and recent files

✅ License activation (if licensed version)

✅ Grobid and AI configurations

What Might Change:

⚠️ New features may add new settings (with sensible defaults)

⚠️ UI layout might improve (your workflows remain the same)

Library Compatibility:

Your existing libraries (PDF files + metadata) are fully compatible across versions. No migration or conversion needed.

First Launch & License

What Happens On First Launch

When you run LibrAIry for the first time on Windows, the application performs several automatic initialization steps before the main interface appears.

Step 1: License Verification

Before anything else, LibrAIry checks your license status. This happens immediately when the application starts, before the main window opens.

Trial Mode (Default):

• If no license is detected, LibrAIry automatically activates in Trial mode
• Trial period: 14 days from first launch
• Full features available during trial (no limitations)
• No registration or email required

Licensed Mode:

• If you have a license key, the application validates it on startup
• License key is checked against activation status
• If license is expired or invalid, the application will not launch

License Check Failure:

If the license check fails (expired trial or invalid license):

• The application displays an error message
• LibrAIry closes immediately without opening the main interface
• You must obtain a valid license or contact support

This verification happens before any windows appear, ensuring unauthorized use is prevented at the earliest stage.

Step 2: Configuration File Creation

After successful license verification, LibrAIry creates its configuration file:

Location: `C:\Users\YourName\Config_LibrAIry.json`

This JSON file stores all your preferences and settings:

• Last opened library path
• Full-text extraction preference (default: enabled)
• Synthesis mode (default: "Comparative (Standard)")
• AI backend selection (default: Ollama local)
• AI model selection (default: "gemma2")
• Google API key (if configured)
• Grobid URL (default: http://127.0.0.1:8070)
• Ollama URL (default: http://127.0.0.1:11434)
• Window sizes and positions
• Auto-start/stop Grobid preferences (default: disabled)

If Config_LibrAIry.json already exists (from previous installation):

• LibrAIry loads your saved settings
• Your preferences, recent libraries, and configurations are preserved
• No re-configuration needed

If Config_LibrAIry.json does not exist (first launch):

• LibrAIry creates the file with default values
• All settings initialized to sensible defaults
• You can customize later through Settings menu

The configuration file is plain-text JSON, human-readable and editable (though manual editing is not recommended).

Step 3: Interface Initialization

After configuration is loaded, LibrAIry builds the main interface:

Window Setup:

• Title: "LibrAIry - Scientific Manager"
• Default size: 1100x700 pixels
• Position: Centered on screen (or last saved position if reopening)
• Window icon loaded (embedded in executable)

Menu Bar Creation:

• File menu: New Library, Open Library, Import PDFs, Network & AI Settings, Grobid Management, Exit
• View menu: Search View, Indexing View
• Tools menu: Extract Metadata, Synthesis, Chat, various utilities
• Help menu: User Manual, About

Main Interface Panels:

• Search View (default): Paper list, search filters, sorting options
• Indexing View: Progress tracking for metadata extraction (hidden initially)
• Status Bar (bottom): License info, library stats, version number

Status Bar Display:

On first launch, the status bar shows:

• License Status (bottom-left):
• Trial mode: "Trial: 14 days remaining" (green text if active, red if near expiry)
• Licensed: "Licensed" or specific license type
• Library Stats (center): "No library loaded | 0 papers"
• Version (bottom-right): "v1.0.8" (or current version)

Step 4: Auto-Start Grobid (Optional)

If you previously configured auto-start Grobid (disabled by default on first launch):

• LibrAIry checks if Docker is installed and running
• If Grobid container exists and is stopped, automatically starts it
• This step only occurs if you enabled "Auto-start Grobid on launch" in settings

On first launch, this step is skipped (auto-start disabled by default).

Step 5: Restore Last Library (If Applicable)

If you previously opened a library:

• LibrAIry automatically opens the last library you were working with
• Papers, metadata, and selection state are restored
• You return to exactly where you left off

On first launch (no previous library):

• Main interface displays empty library view
• Message: "No library loaded"
• You'll create your first library next (see "Creating Your First Library" section)

Understanding License Status

LibrAIry displays license information in two places:

1. Status Bar (Bottom-Left Corner)

During normal use, a compact license indicator shows:

• "Trial: X days remaining" - Trial mode, X days left
• "Licensed" - Full license active

2. About Dialog (Help → About LibrAIry)

For detailed license information:

1. Click Help menu → About LibrAIry
2. Dialog shows:
3. Status: "Active" (green) or "Expired" (red)
4. Type: "Trial", "Professional", "Academic", etc.
5. Days Remaining: Number (for Trial licenses only)
6. PDFs Remaining: Number (for limited Trial versions only)

License Types:

Based on code implementation, LibrAIry supports:

• Trial: 14-day full-featured trial, may have PDF limits
• Professional: Full commercial license
• Academic: Educational/research license
• Unlimited: No restrictions (developer/special licenses)

Trial Mode Details

What You Get:

• 14 days of full access from first launch
• All features unlocked (Metadata Extraction, Search, Chat, Synthesis)

• Right: "v1.0.8" (version number)

The interface is ready to use. Your next step is creating your first library.

Verifying Successful First Launch

To confirm LibrAIry launched correctly:

Check 1: Main Window Visible

• Title bar shows: "LibrAIry - Scientific Manager"
• Window is responsive (can resize, move)

Check 2: License Status Displayed

• Status bar (bottom-left) shows license info
• Should say "Trial: 14 days remaining" for new installations
• If blank or missing, license system failed

Check 3: Configuration File Created

• Navigate to: `C:\Users\YourName\`
• File `Config_LibrAIry.json` should exist
• If missing, LibrAIry cannot save settings

Check 4: Menu Bar Functional

• Click "Help" → "About LibrAIry"
• About dialog should open showing version and license details

If any check fails, see Troubleshooting section or reinstall LibrAIry.

Common First Launch Issues

Issue: Application closes immediately after launch

Cause: License check failed (trial expired on previous install, or invalid license)

Solution:

• Check if you previously installed LibrAIry Trial (trial may have expired)
• Delete `Config_LibrAIry.json` to reset trial period (note: this may violate license terms)
• Purchase valid license

Issue: "Config_LibrAIry.json" not created

Cause: No write permissions in user directory

Solution:

• Run LibrAIry as administrator once (right-click → "Run as administrator")
• Check antivirus isn't blocking file creation
• Verify `C:\Users\YourName\` folder is writable

Issue: Status bar shows "Dev Mode" instead of "Trial"

Cause: Running developer version without LicenseLib.py

This is normal for developer builds. Ignore if you're testing pre-release versions.

Issue: License status shows expired immediately

Cause: System clock manipulation or previous trial installation

Solution:

• Ensure Windows system clock is correct
• Contact support if issue persists
• May require purchasing license

Next Steps After First Launch

5. Tags (if incomplete)

Done! Now you can search, cite, and analyze.

Understanding Extraction Results

What Is Metadata Extraction:

When you import PDF files into LibrAIry, the application automatically attempts to extract bibliographic metadata (title, authors, year, journal, abstract, etc.) from each PDF. This extraction process is powered by Grobid, a machine learning library specialized in parsing academic papers.

The extraction results vary widely depending on PDF quality, structure, and whether the document is text-based or scanned. LibrAIry categorizes extraction outcomes into distinct status levels, helping you quickly identify which papers extracted successfully, which need manual correction, and which are scanned documents requiring special handling.

Understanding these extraction status indicators is essential for maintaining a high-quality library and knowing when papers need attention. Each status appears as a tag next to the paper's title in the library view, providing instant visual feedback on metadata quality.

Extraction Status Levels:

LibrAIry assigns one of five extraction status tags to every imported paper. These tags reflect the quality and completeness of extracted metadata:

[Metadata OK] - Complete Extraction Success

[Partial Metadata] - Incomplete Extraction

[No Metadata] - Extraction Failed

[Scanned Article] - Scanned/Image-based PDF Detected

[Modified Metadata] - User-Edited Metadata

These statuses appear in the library view appended to paper titles (except for [Metadata OK] and [Modified Metadata], which display no visible tag). For example, you might see:

"Climate Change Impacts on Agriculture [Partial Metadata]"

"Neural Networks in Computer Vision [Scanned Article]"

"Machine Learning Methods" (no tag = [Metadata OK] or [Modified Metadata])

Detailed Status Descriptions:

[Metadata OK] - Complete Extraction Success

This status indicates Grobid successfully extracted all four critical metadata fields:

• Title (more than 3 characters)
• Author (not "Unknown")
• Year (4-digit valid year, not "xxxx")
• Journal (more than 2 characters)

Papers with [Metadata OK] status have complete, high-quality metadata suitable for citations, searches, and AI features. These papers typically don't need any manual intervention.

Visual display: No tag appears in the title (clean display without status indicator)

What you see in library:

• Title appears normally without any bracketed tag
• All metadata fields populated correctly
• Author names properly formatted (e.g., "Smith, J. and Jones, R.")
• Year shows valid 4-digit year (e.g., "2023")
• Journal field contains publication venue

When this occurs:

• PDF is well-structured with clear metadata
• Text is machine-readable (not scanned)
• Grobid successfully parsed the document structure
• All essential bibliographic information is present

No action needed: These papers are ready to use with all LibrAIry features.

[Partial Metadata] - Incomplete Extraction

This status indicates Grobid extracted some metadata but not all four critical fields. At minimum, the paper has title plus at least one other field (year, author, or journal), but not all four.

Common partial extraction patterns:

• Title + Year + Author (missing journal)
• Title + Journal (missing author and/or year)
• Title + Year (missing author and journal)

Papers with [Partial Metadata] are usable but may cause issues with citations, sorting, or searching. They need manual metadata completion for optimal library quality.

Visual display: Title shows "[Partial Metadata]" tag

What you see in library:

• Title: "Machine Learning Methods [Partial Metadata]"
• Some fields populated, others showing defaults ("Unknown", "xxxx", or empty)
• Enough information to identify the paper but incomplete for citations

When this occurs:

• PDF has non-standard structure (unusual formatting)
• Header/first page is malformed or unconventional
• Some metadata is embedded but not all
• Conference papers (often lack journal field)
• Pre-prints or working papers (incomplete metadata)

Recommended action: Right-click → "✏️ Edit Metadata" to manually add missing fields. Common fixes include adding the author name, year, or journal that Grobid missed.

[No Metadata] - Extraction Failed

This status indicates Grobid could not extract meaningful metadata. The paper either has only a title, or even the title extraction failed (falling back to filename). This represents a complete extraction failure.

Papers with [No Metadata] have minimal usable information and are difficult to search, cite, or use with AI features. They require manual metadata entry.

Visual display: Title shows "[No Metadata]" tag

What you see in library:

• Title: "document.pdf [No Metadata]" (or actual filename if title extraction failed)
• Author: "Unknown"
• Year: "xxxx" (placeholder)
• Journal: Empty or missing
• Abstract: Empty or missing

When this occurs:

• PDF structure is highly non-standard
• The paper uses unusual formatting Grobid can't parse
• First few pages contain no metadata (e.g., cover pages, tables of contents)
• PDF is corrupt or malformed
• Text is present but structure is unrecognizable

Warning: [No Metadata] is NOT the same as [Scanned Article]. The PDF is readable (contains text), but Grobid couldn't interpret the structure to extract metadata.

Recommended action: Right-click → "✏️ Edit Metadata" to manually enter all metadata fields. Consider using "Inspect Extracted Text" first to verify the PDF is readable.

[Scanned Article] - Scanned/Image-based PDF Detected

This status indicates the PDF is scanned (image-based) rather than text-based. LibrAIry detects this BEFORE attempting Grobid extraction by checking if text extraction yields less than 200 characters.

Scanned PDFs contain images of text rather than actual text, making metadata extraction impossible and limiting LibrAIry's AI features. These papers cannot be processed by Chat or Synthesis in full-text mode.

Visual display: Title shows "[Scanned Article]" tag

What you see in library:

• Title: Filename (e.g., "scanned_paper.pdf [Scanned Article]")
• Author: "Unknown"
• Year: "xxxx"
• Journal: Empty
• Abstract: Empty

When this occurs:

• PDF was created by scanning physical pages (photocopier, document scanner)
• PDF contains only images of text, not actual text data
• Older papers digitized before OCR (Optical Character Recognition) was common
• Low-quality scans that OCR couldn't process

Detection mechanism: LibrAIry extracts text from the PDF and checks:

1. Was extraction successful? (is_readable)
2. Does extracted text contain at least 200 characters?

If either check fails → [Scanned Article]

Limitations with scanned PDFs:

• Metadata extraction completely unavailable
• Full-text Chat mode won't work (abstract-only mode may still work if you add abstract manually)
• Full-text Synthesis won't work
• Search only works on manually entered metadata
• "Inspect Extracted Text" will show gibberish or empty content

Recommended action: Two options:

1. Manual metadata entry: Right-click → "✏️ Edit Metadata" to add title, authors, year, journal, and abstract manually. This enables basic LibrAIry features and abstract-only AI modes.
2. OCR the PDF: Use external OCR software (Adobe Acrobat, ABBYY FineReader) to convert the scanned PDF to text-based PDF, then re-import to LibrAIry for automatic extraction.

Note: LibrAIry does not include OCR capabilities. You must use external tools to OCR scanned documents.

[Modified Metadata] - User-Edited Metadata

This status indicates you manually edited the paper's metadata through "✏️ Edit Metadata" dialog. Papers with this status are protected from automatic re-extraction to preserve your manual corrections.

When you edit metadata, LibrAIry marks the paper as "user-modified" and sets extraction_status to "[Modified Metadata]". This prevents the "Enrich Metadata (Full Text)" and "Retry '[No Metadata]' & '[Partial]'" functions from overwriting your changes.

Visual display: No tag appears in the title (clean display like [Metadata OK])

What you see in library:

• Title appears normally without tag
• Metadata fields contain your manual edits
• Paper looks identical to [Metadata OK] papers

When this occurs:

• You used Right-click → "✏️ Edit Metadata"
• You saved changes in the metadata editor
• LibrAIry marked the record as user-modified

Protection: Papers with [Modified Metadata] status are excluded from:

• Batch metadata re-extraction ("Retry '[No Metadata]' & '[Partial]'")
• Individual re-extraction via "Enrich Metadata (Full Text)" - this WILL overwrite unless specifically checked
• Automatic metadata updates

Recommended: Only manually edit metadata when automatic extraction fails or produces errors. Once edited, the paper is protected from future automatic improvements.

Removing protection: To allow re-extraction of a user-modified paper, you'd need to manually edit the library JSON file and remove the "user_modified" flag or change the "extraction_status" field. This is advanced and not recommended for most users.

How Extraction Statuses Are Assigned:

LibrAIry follows a specific decision tree when assigning extraction status:

Step 1: Scanned Document Detection (Before Grobid)

Before sending the PDF to Grobid, LibrAIry extracts text and checks:

• Is text extraction successful?
• Does extracted text contain ≥ 200 characters?

If NO to either → [Scanned Article] (stop, don't call Grobid)

If YES → Proceed to Step 2

Step 2: Grobid Extraction

LibrAIry sends the PDF to Grobid for metadata extraction. Grobid returns XML or BibTeX containing extracted fields.

Step 3: Field Validation

LibrAIry validates each extracted field:

Title validation:

• Must exist and be > 3 characters
• If missing or too short → Use filename as title

Author validation:

• Must exist and be > 2 characters
• Must not be exactly "Unknown" (case-insensitive)
• If missing → Set to "Unknown"

Year validation:

• Must be exactly 4 digits
• Must be a valid year (not "xxxx")
• If missing or invalid → Set to "xxxx"

Journal validation:

• Must exist and be > 2 characters
• If missing → Set to empty string

Step 4: Status Assignment

Based on validated fields, assign status according to hierarchy:

Priority 1 - All 4 critical fields present:

has_title AND has_author AND has_year AND has_journal

→ [Metadata OK]

Priority 2 - Partial metadata (title + at least 1 other field):

(has_title AND has_year) OR

(has_title AND has_author) OR

(has_title AND has_journal)

→ [Partial Metadata]

Priority 3 - Extraction failed:

None of the above conditions met

→ [No Metadata]

Step 5: User Modifications

When user manually edits metadata:

Set extraction_status → [Modified Metadata]

Set user_modified flag → True

This overrides the automatic status and protects from re-extraction.

Visual Indicators In The Library:

Extraction status affects how papers appear in the library view:

Papers with tags visible:

• Title + [Partial Metadata] - Orange/yellow visual indicator
• Title + [No Metadata] - Red visual indicator
• Title + [Scanned Article] - Gray visual indicator

Papers without tags (clean display):

• Title (no tag) - Could be [Metadata OK] or [Modified Metadata]
• Both indicate good-quality, complete metadata

Sorting and filtering:

Papers can be sorted or filtered by extraction status, making it easy to find all papers needing attention. For example, you can quickly list all [Partial Metadata] papers to systematically correct them.

Batch Operations By Status:

LibrAIry provides a batch operation specifically for improving extraction results:

Tools → Retry '[No Metadata]' & '[Partial]'

This function re-runs Grobid extraction on all papers tagged with [No Metadata] or [Partial Metadata], attempting to extract metadata again (potentially with improved settings or after Grobid updates).

How it works:

1. Scans library for papers with [No Metadata] or [Partial Metadata] status
2. Excludes protected papers ([Scanned Article] and [Modified Metadata])
3. Shows confirmation dialog listing how many papers will be processed
4. Re-runs Grobid extraction on each paper
5. Updates extraction status based on new results

Protection: Papers with [Scanned Article] and [Modified Metadata] are automatically excluded from batch re-extraction to preserve manual edits and avoid wasting time on scanned documents.

When to use:

• After updating Grobid configuration or version
• After initially importing papers with poor extraction
• When you suspect extraction quality can be improved

Warning: This can take significant time for large numbers of papers (several minutes for 100+ papers). The operation shows progress and can be stopped if needed.

Improving Extraction Results:

For different status levels, different improvement strategies work best:

For [Partial Metadata]:

1. Right-click → "✏️ Edit Metadata"
2. Add missing fields (typically author, year, or journal)
3. Save changes
4. Paper becomes [Modified Metadata] and is protected from overwrites

For [No Metadata]:

1. Right-click → "Inspect Extracted Text" to verify PDF is readable
2. If readable but extraction failed:
3. Try Right-click → "Enrich Metadata (Full Text)" for deeper extraction
4. If still fails, manually edit metadata
5. If text is gibberish/empty, PDF might be scanned → See [Scanned Article] guidance

For [Scanned Article]:

1. Option A - OCR the PDF:
2. Use external OCR software (Adobe Acrobat, ABBYY FineReader, etc.)
3. Replace scanned PDF with OCR'd version
4. Re-import to LibrAIry
5. Extraction should succeed on OCR'd version

1. Option B - Manual metadata entry:
2. Right-click → "✏️ Edit Metadata"
3. Manually type all metadata fields
4. Enables basic LibrAIry features (search, tagging)
5. AI features limited to abstract-only mode

Extraction Status Statistics:

After importing or extracting metadata from papers, LibrAIry shows extraction statistics:

Example message:

```

Extraction completed!

✅ Metadata OK: 45

⚠️ Partial Metadata: 12

❌ No Metadata: 3

📄 Scanned Articles: 5

```

This helps you understand extraction quality across your library and identify how many papers need attention.

The statistics appear in:

• Import completion message
• After "Retry '[No Metadata]' & '[Partial]'" completes
• After batch "Enrich Metadata (Full Text)" operations

Common Extraction Scenarios:

Scenario 1: Recent journal article from major publisher

• PDF structure: Standard, well-formatted
• Expected result: [Metadata OK]
• All fields extracted correctly
• No action needed

Scenario 2: Conference paper from IEEE/ACM

• PDF structure: Standard header, but no journal field (conference name in different location)
• Expected result: [Partial Metadata]
• Title, authors, year extracted
• Journal field empty (conference papers often lack this)
• Action: Add conference name to journal field manually

Scenario 3: Pre-print from arXiv

• PDF structure: Minimal metadata, author-formatted
• Expected result: [Partial Metadata] or [No Metadata]
• Structure varies widely by author
• Action: Manually add missing fields, especially publication venue

Scenario 4: Old scanned paper (pre-2000)

• PDF structure: Image-based scan
• Expected result: [Scanned Article]
• No text extraction possible
• Action: OCR the PDF or manually enter all metadata

Scenario 5: Book chapter

• PDF structure: Non-standard (book format, not article format)
• Expected result: [No Metadata] or [Partial Metadata]
• Grobid optimized for articles, not books
• Action: Manually enter metadata

Scenario 6: Technical report

• PDF structure: Varies widely (government, company, or research institute format)
• Expected result: [Partial Metadata] or [No Metadata]
• Non-standard formatting confuses Grobid
• Action: Manually complete metadata

Error Messages And Troubleshooting:

"Connection Refused" during extraction

Error message:

```

Connection Refused.

1. Check if Grobid is running (Settings > Start Grobid).
2. Check your Firewall (Allow port 8070).

```

Cause: LibrAIry cannot connect to Grobid service

Solutions:

1. Go to File → Network & AI Settings → Start Grobid
2. Check that Docker is running (required for Grobid)
3. Check firewall settings allow localhost port 8070
4. Verify Grobid URL is correct (default: http://127.0.0.1:8070)

Extraction takes extremely long time

Cause: Processing very large PDFs or many pages

Solutions:

1. LibrAIry automatically trims PDFs to first 5 pages (header mode) or 50 pages (full-text mode)
2. If still slow, check PDF file size - extremely large files (100+ MB) may timeout
3. Consider header-only extraction instead of full-text for faster processing

All papers show [No Metadata]

Cause: Grobid not running or configuration issue

Solutions:

1. Check Grobid is running (File → Network & AI Settings)
2. Verify Grobid URL configuration
3. Test with a known-good PDF (recent journal article from major publisher)
4. Check Docker logs for Grobid errors

Best Practices:

For optimal extraction results:

1. Use high-quality PDFs: Download from publishers when possible rather than scanning
2. Check extraction status immediately: After import, review which papers need attention
3. Systematically fix [Partial Metadata]: These are easiest to correct (only 1-2 missing fields)
4. Manually edit important papers: Papers you'll cite frequently deserve perfect metadata
5. OCR scanned documents: Don't manually enter metadata for scanned papers if you can OCR them
6. Use batch re-extraction wisely: After initial import, try "Retry '[No Metadata]' & '[Partial]'" once
7. Protect manual edits: Remember that [Modified Metadata] prevents overwrites

Basic Search

What Is Basic Search:

Basic Search is the quickest, most intuitive way to find papers in your library. Simply type a word or phrase into the search box at the top of the main window, and LibrAIry instantly filters your library to show only papers matching your query. As you type, the results update in real-time, making it easy to refine your search on the fly.

Basic Search looks across all major metadata fields simultaneously: titles, authors, abstracts, journals, keywords, and years. This comprehensive approach means you don't need to remember exactly where you saw a term—if it appears anywhere in a paper's metadata, Basic Search will find it.

The search is case-insensitive and finds partial matches, so typing "climate" will match "climate," "Climate," "climatic," and "microclimates." This forgiving approach ensures you find relevant papers even if you don't remember the exact wording or capitalization.

How To Use Basic Search:

Starting a Search: Click in the search box at the top of the LibrAIry window, or press Ctrl+F (Windows/Linux) or Cmd+F (Mac) to activate it with your keyboard. The search box is always visible and ready to use—no menus to navigate.

Entering Your Query: Type your search term. As you type, the library view updates automatically to show matching papers. For example, typing "smith" immediately shows all papers with "Smith" in any author field, "smith" in the title, or "smith" appearing in abstracts or keywords.

Refining Results: If you get too many results, add more words to narrow down. Typing "smith climate" shows papers that contain both "smith" AND "climate" somewhere in their metadata. The more specific your query, the fewer but more relevant results you'll see.

Clearing Search: Click the "X" button in the search box or delete all text to return to viewing your complete library. You can also press Escape to quickly clear the search.

Working with Results: Once you've found the papers you want, you can select them (click to highlight), open them (double-click), tag them, or use them with other features like Chat or Synthesis. The search results remain filtered until you clear the search or enter a new query.

What Basic Search Looks For:

Basic Search examines these metadata fields in every paper:

Title: The full title of the paper as extracted by Grobid or manually entered. This is usually the most important field for finding specific papers.

Authors: All author names, including first authors, co-authors, and last authors. Searching for an author's last name (e.g., "Johnson") finds all their papers regardless of author position.

Abstract: The paper's abstract text. This is particularly useful for finding papers on specific topics or using specific methods, since abstracts typically mention the main focus and approach of the study.

Journal/Conference: The publication venue. Search for "Nature" to find all Nature papers, or "ICLR" to find conference papers from the International Conference on Learning Representations.

Keywords: Author-provided keywords or tags you've added manually. These are often precise descriptors of paper content.

Year: Publication year. Searching for "2023" shows all papers published in 2023.

DOI and other identifiers: If you know a paper's DOI or other identifier, you can search for it directly.

The search algorithm treats all these fields equally, so a match in the title is weighted the same as a match in the abstract. For more control over which fields to search, use Boolean Search (see next section).

Search Behavior And Matching:

Partial Matching: You don't need to type complete words. "cogn" matches "cognition," "cognitive," "recognition," and "metacognition." This is helpful when you remember only part of a term or want to catch variant forms.

Multiple Terms: When you type multiple words separated by spaces (e.g., "neural network"), Basic Search finds papers containing BOTH terms anywhere in their metadata. The terms don't need to be adjacent or in the same field—one could be in the title and one in the abstract.

Case Insensitivity: "CLIMATE," "Climate," and "climate" all produce identical results. You never need to worry about capitalization.

Special Characters: Basic Search handles hyphens, apostrophes, and most punctuation gracefully. Searching for "self-driving" finds papers with "self-driving," "self driving," and "selfdriving."

Accented Characters: The search respects accents in names and terms. "Müller" and "Muller" are treated as different searches, ensuring you find the exact author you're looking for.

Practical Basic Search Examples:

Finding Papers by Author:

• Search: "zhang"
• Result: All papers with "Zhang" as an author (first, middle, or last author)
• Use case: Reviewing all work by a particular researcher before a meeting or citation

Finding Papers on a Topic:

• Search: "machine learning"
• Result: All papers with "machine learning" appearing in title, abstract, or keywords
• Use case: Gathering papers for a literature review section on ML methods

Finding Papers from a Specific Journal:

• Search: "science"
• Result: Papers published in journals with "Science" in the name (Science, Nature Science, Computer Science, etc.)
• Refinement: "science 2023" to narrow to recent Science journal papers

Finding Recent Papers:

• Search: "2024"
• Result: All papers published in 2024
• Use case: Reviewing recent additions to your library

Finding Methodology Papers:

• Search: "meta-analysis"
• Result: Papers mentioning meta-analysis in their title or abstract
• Use case: Finding methodological papers for your methods section

Combining Author and Topic:

• Search: "smith climate"
• Result: Papers by Smith about climate, or papers about Smith's climate work
• Use case: Finding specific papers at the intersection of author and topic

Finding Conference Papers:

• Search: "neurips"
• Result: Papers from NeurIPS conference
• Use case: Reviewing papers from a specific conference you attended

When To Use Basic Search:

Basic Search is ideal when:

• You're looking for papers on a general topic ("climate change," "neural networks")
• You remember an author's name but not the exact paper ("johnson")
• You want to quickly filter your library without complex syntax
• You're exploring what you have on a topic before diving deeper
• You need fast results and don't require precision

Basic Search is NOT ideal when:

• You need to search only specific fields (e.g., only titles, not abstracts)
• You want to exclude certain terms (e.g., papers about X but NOT Y)
• You need complex logical combinations (this AND that OR the_other)
• You want exact phrase matching

→ For these cases, use Boolean Search (next section)

Tips For Effective Basic Search:

Start Broad, Then Narrow: Begin with a single keyword to see what you have, then add more terms to refine. Starting with "climate" might return 100 papers; adding "adaptation" narrows to 20 more relevant papers.

Use Distinctive Terms: Search for the most specific, distinctive term that describes what you want. "fMRI" is better than "brain imaging" because it's more specific and less likely to return irrelevant papers.

Try Variations: If one search term doesn't work, try synonyms or related terms. "AI" vs. "artificial intelligence," "ML" vs. "machine learning," "stats" vs. "statistics."

Search by What You Remember: Don't overthink it. If you remember the paper was about dolphins and learning, search "dolphin learning." The flexible matching will likely find it.

Use Year for Recency: Adding a recent year (2023, 2024) is a quick way to filter for recent papers without complex queries.

Author Last Names Work Best: Searching for just the last name is usually sufficient for finding an author's work, and avoids issues with first name variations or initials.

Search Performance:

Basic Search is optimized for speed. Even in libraries with hundreds of papers, searches complete instantly—typically in under 100 milliseconds. This real-time responsiveness makes it practical to iteratively refine searches by typing, observing results, adding terms, and observing again.

The search operates entirely on LibrAIry's internal database of extracted metadata, not on the PDF files themselves. This means search speed doesn't depend on PDF size or complexity—a 2-page letter and a 50-page technical report search equally fast.

Understanding Search Results:

When a search returns results, papers appear in the main library view just as they normally do, but filtered. All the usual information displays—title, authors, year, journal, thumbnail—making it easy to identify the paper you want.

If no papers match your search, the library view shows "No papers match your search criteria" or similar message. This might mean:

• The term doesn't appear in any metadata (try different terms or check for typos)
• The metadata for your papers is incomplete (run "Extract Metadata" to improve coverage)
• You're searching for something that genuinely isn't in your collection

The number of results typically appears in the status bar at the bottom of the window, showing "Showing 15 of 247 papers" or similar, helping you gauge how selective your search has been.

Boolean Search

What Is Boolean Search:

Boolean Search provides advanced querying capabilities using logical operators (AND, OR, NOT) and field-specific searching. While Basic Search is like asking "show me papers related to this topic," Boolean Search lets you construct precise, complex queries like "papers by Smith OR Jones, published after 2020, about climate BUT NOT economics, with methodology in the title."

Boolean Search follows the conventions of academic search engines and library databases, making it familiar to anyone who has used PubMed, Google Scholar, Web of Science, or similar research tools. The syntax is designed to be both powerful and readable, using common sense operators rather than cryptic symbols.

Boolean operators let you combine search terms in logical ways: AND narrows results by requiring all terms, OR broadens results by accepting any term, and NOT excludes unwanted terms. You can also group terms with parentheses, search specific fields, and use wildcards for pattern matching.

Boolean Operators:

AND Operator (narrowing):

• Syntax: `climate AND adaptation`
• Meaning: Papers must contain BOTH "climate" AND "adaptation"
• Result: Fewer, more specific papers than searching either term alone
• Use case: Finding papers at the intersection of two topics

Example: `machine learning AND healthcare`

Returns: Papers discussing machine learning applications in healthcare

Does NOT return: Papers only about machine learning or only about healthcare

OR Operator (broadening):

• Syntax: `climate OR weather`
• Meaning: Papers must contain EITHER "climate" OR "weather" (or both)
• Result: More papers than searching either term alone
• Use case: Finding papers using synonyms or related concepts

Example: `AI OR "artificial intelligence" OR "machine learning"`

Returns: Papers mentioning any of these terms

Use case: Catching papers regardless of which terminology they use

NOT Operator (excluding):

• Syntax: `climate NOT economics`
• Meaning: Papers must contain "climate" but must NOT contain "economics"
• Result: Subset of papers, with unwanted topics filtered out
• Use case: Excluding off-topic papers or specific subtopics

Example: `neural networks NOT artificial`

Returns: Papers about biological neural networks, excluding AI papers

Does NOT return: Papers mentioning "artificial neural networks"

Operator Precedence:

When combining operators, NOT is evaluated first, then AND, then OR:

• `A OR B AND C` is interpreted as `A OR (B AND C)`
• `A AND B NOT C` is interpreted as `(A AND B) NOT C`

To override precedence, use parentheses (see next section).

Grouping With Parentheses:

Parentheses let you control the order of operations in complex queries, just like in mathematics:

Basic Grouping:

• Query: `(climate OR weather) AND adaptation`
• Meaning: Papers about adaptation that mention EITHER climate OR weather
• Without parentheses: `climate OR weather AND adaptation` would mean "climate" OR "papers about both weather and adaptation"

Multiple Groups:

• Query: `(machine learning OR deep learning) AND (vision OR image)`
• Meaning: Papers using ML/DL approaches in vision/image domains
• Result: Highly specific intersection of two concept groups

Nested Groups:

• Query: `((fMRI OR PET) AND cognition) NOT disease`
• Meaning: Cognitive neuroscience studies using fMRI or PET, excluding disease-related research
• Use case: Finding basic cognitive research excluding clinical applications

Complex Boolean Logic:

• Query: `(smith OR jones) AND (2020 OR 2021 OR 2022) AND climate NOT economics`
• Meaning: Recent climate papers by Smith or Jones, excluding economic topics
• Result: Very precise subset of library

Field-Specific Searching:

Boolean Search lets you target specific metadata fields rather than searching everywhere:

Title Search:

• Syntax: `title:climate`
• Meaning: "climate" must appear in the title
• Use case: Finding papers where climate is the main topic (not just mentioned)

Example: `title:"neural networks" AND author:lecun`

Returns: Papers with "neural networks" in the title, authored by LeCun

Author Search:

• Syntax: `author:smith`
• Meaning: "smith" must appear in author list
• Use case: Finding all papers by a specific author

Example: `author:smith OR author:jones`

Returns: Papers by either Smith or Jones

Abstract Search:

• Syntax: `abstract:methodology`
• Meaning: "methodology" must appear in abstract
• Use case: Finding papers discussing specific methods

Example: `abstract:meta-analysis AND year:2023`

Returns: 2023 papers mentioning meta-analysis in abstract

Journal Search:

• Syntax: `journal:nature`
• Meaning: Published in journals containing "nature"
• Use case: Finding papers from prestigious journals

Example: `journal:"nature climate change" AND year:2024`

Returns: 2024 papers from Nature Climate Change

Year Search:

• Syntax: `year:2023` or `year:>2020` or `year:2020-2023`
• Meaning: Published in specified year or year range
• Use case: Finding recent or historical papers

Examples:

• `year:2024` → Papers from 2024
• `year:>2020` → Papers from 2021 onwards
• `year:2018-2023` → Papers from 2018 through 2023

Keyword Search:

• Syntax: `keyword:statistics`
• Meaning: "statistics" appears in keywords field
• Use case: Finding papers tagged with specific keywords

Example: `keyword:quantitative OR keyword:qualitative`

Returns: Papers tagged with either research approach

Phrase Searching:

Exact Phrases:

Use quotation marks to search for exact phrases rather than individual words:

• Query: `"machine learning"`
• Meaning: The exact phrase "machine learning" (words adjacent and in this order)
• Without quotes: `machine learning` finds papers with "machine" AND "learning" anywhere
• With quotes: Finds only papers with the exact phrase "machine learning"

Examples:

• `"climate change adaptation"` → Exact three-word phrase
• `"deep neural networks"` → Exact phrase (excludes "neural networks" without "deep")
• `title:"systematic review"` → Exact phrase in title only

Combining Phrases with Operators:

• `"machine learning" OR "deep learning"` → Papers with either exact phrase
• `"climate change" AND adaptation` → Exact phrase "climate change" plus word "adaptation"
• `author:"smith j" AND "meta-analysis"` → Papers by J. Smith containing exact phrase

Wildcard Searching:

**Asterisk Wildcard (*)**:

The asterisk matches any number of characters (including zero):

• `climat*` → Matches climate, climatic, climatology, climates
• `neuro*` → Matches neuroscience, neurology, neuroimaging, neuroplasticity
• `*ology` → Matches psychology, sociology, methodology, biology

Use case: Catching word variations without listing every form

Question Mark Wildcard (?):

The question mark matches exactly one character:

• `wom?n` → Matches woman, women
• `colo?r` → Matches color, colour
• `analys?s` → Matches analysis, analyses

Use case: Handling spelling variations or singular/plural forms

Combining Wildcards with Operators:

• `climat* AND adapt*` → Papers about climate/climatic/etc. and adaptation/adaptive/etc.
• `neuro* OR psych*` → Papers in neuroscience or psychology fields
• `title:meta-anal*` → Papers with meta-analysis/meta-analytic/etc. in title

Practical Boolean Search Examples:

Finding Recent Papers by Multiple Authors:

• Query: `(author:smith OR author:jones OR author:williams) AND year:>2022`
• Result: Papers by any of these authors published 2023 or later
• Use case: Following multiple researchers' recent work

Methodological Focus:

• Query: `(abstract:randomized OR abstract:"controlled trial") AND NOT abstract:meta-analysis`
• Result: Primary RCT studies, excluding meta-analyses
• Use case: Finding original experimental studies

Topic Intersection:

• Query: `(title:climate OR title:environment*) AND (abstract:machine AND abstract:learning)`
• Result: Environmental papers using machine learning methods
• Use case: Finding interdisciplinary applications

Journal and Year Filter:

• Query: `(journal:nature OR journal:science) AND year:2020-2024`
• Result: Papers from Nature or Science journals, 2020-2024
• Use case: Finding high-impact recent papers

Excluding Unwanted Topics:

• Query: `neural AND network* NOT (artificial OR computer OR deep)`
• Result: Biological neural network papers, excluding AI/ML papers
• Use case: Separating neuroscience from computer science

Author with Topic Constraint:

• Query: `author:lecun AND (title:*vision OR title:*image) AND year:>2015`
• Result: Recent vision/image papers by LeCun
• Use case: Finding specific author's work in specific domain

Multi-field Complex Query:

• Query: `(title:review OR title:meta-analysis) AND (author:smith OR author:jones) AND year:2018-2023 AND NOT keyword:economics`
• Result: Recent review papers by Smith or Jones, excluding economics
• Use case: Finding specific types of papers with multiple constraints

Boolean Search Syntax Summary:

Operators:

• AND → Both terms required (narrows)
• OR → Either term acceptable (broadens)
• NOT → Exclude term (filters)

Grouping:

• (term1 OR term2) → Group operations
• Nested parentheses allowed

Field Specifiers:

• field:term → Search specific field
• Supported fields: title, author, abstract, journal, year, keyword

Special Syntax:

• "exact phrase" → Match exact word sequence
• wildcard* → Match any ending
• wild?ard → Match single character
• year:>2020 → Year greater than 2020
• year:2018-2023 → Year range

Examples:

• `title:"climate change" AND year:>2020`
• `(author:smith OR author:jones) AND abstract:meta-analysis`
• `climat* AND adapt* NOT econom*`

Tips For Effective Boolean Search:

Start Simple, Build Complexity: Begin with basic Boolean queries and add complexity gradually. Test each component before combining.

Use Parentheses Liberally: When in doubt, use parentheses to make your query logic explicit. `(A OR B) AND C` is clearer than `A OR B AND C`.

Leverage Field Searches: Searching `title:` when you want main topic and `abstract:` when you want methods mentioned gives more precise results than searching everywhere.

Combine Wildcards with Boolean: `(climat* OR environment*) AND (adapt* OR resilien*)` catches many related terms efficiently.

Test Incrementally: Build complex queries piece by piece, checking results after each addition. If `A AND B` returns what you want, then add `AND NOT C` to refine further.

Document Your Queries: For important searches you'll repeat, save the query text in a document. Boolean queries can be complex and hard to remember.

Use NOT Sparingly: NOT can exclude more than intended. `climate NOT economics` might exclude climate economics papers you actually want.

When To Use Boolean Search:

Boolean Search is ideal when:

• You need precise control over which papers match
• You're searching for papers at the intersection of multiple topics
• You want to exclude specific unwanted subtopics
• You know exactly which field contains the term you want
• You're conducting systematic reviews requiring reproducible search strategies
• Basic Search returns too many irrelevant papers

Use Basic Search when Boolean Search would be overkill—don't build `author:smith AND year:2023` if simply typing "smith 2023" suffices.

Sorting

What Is Sorting:

Sorting organizes your library or search results in a specific order, making it easier to find what you need or understand your collection at a glance. While Search filters which papers appear, Sorting controls how those papers are arranged.

LibrAIry offers multiple sorting options, each useful for different tasks. You might sort by year to see your newest papers first, by author to group papers by researcher, by title for alphabetical browsing, or by journal to see which publications you've collected most from. Sorting is especially powerful when combined with Search—for example, searching for "climate" and sorting by year shows climate papers chronologically, revealing how the field has evolved.

Sorting is non-destructive and instant. You can change sort order as often as you like without affecting your library structure or Search results. Papers are simply rearranged visually; no data changes.

Available Sort Options:

Sort by Title (A-Z or Z-A):

Arranges papers alphabetically by title. This is useful for:

• Finding a specific paper when you remember its title
• Browsing your collection alphabetically
• Identifying duplicate papers (same title appears together)
• Creating alphabetically organized reading lists

Ascending (A-Z) shows titles starting with A at the top; descending (Z-A) shows titles starting with Z at the top. Numbers sort before letters, so papers titled "2023 Survey..." appear before "Analysis of..."

Sort by Author (A-Z or Z-A):

Arranges papers alphabetically by first author's last name. This is useful for:

• Grouping papers by the same lead author
• Reviewing all work by a specific researcher
• Identifying your most-collected authors
• Preparing author-focused literature reviews

When multiple papers have the same first author, they're sub-sorted by second author, then by year. Papers with missing author information appear at the end of the list.

Sort by Year (Newest First or Oldest First):

Arranges papers chronologically by publication year. This is useful for:

• Seeing your most recent papers at the top
• Understanding chronological development of a field
• Identifying gaps in your collection (e.g., nothing from 2018-2020)
• Prioritizing reading newest research

"Newest first" puts 2024 papers at the top, then 2023, 2022, etc. "Oldest first" reverses this. Papers with missing years appear at the end.

Sort by Journal/Conference (A-Z or Z-A):

Arranges papers alphabetically by publication venue. This is useful for:

• Grouping papers from the same journal
• Seeing which journals you've collected most from
• Identifying gaps in journal coverage
• Preparing venue-specific analyses

Papers from "Nature" appear together, "Science" papers together, conference papers together. Papers with missing venue information appear at the end.

Sort by Date Added (Newest First or Oldest First):

Arranges papers by when you added them to LibrAIry. This is useful for:

• Finding recently imported papers
• Tracking your reading workflow (newest additions = what to read next)
• Reviewing what you've collected over time
• Identifying papers you imported but haven't processed yet

"Newest first" shows today's imports at the top. This is the default sort order in LibrAIry.

Sort by Relevance (Search Results Only):

When viewing search results, papers can be sorted by relevance to your query. This is useful for:

• Finding the most relevant papers for your search first
• Quickly identifying key papers in a large result set
• Prioritizing which results to examine

Relevance is calculated based on where and how often search terms appear—papers with terms in titles rank higher than papers with terms only in abstracts, and papers with multiple occurrences rank higher than papers with single occurrences.

How To Sort:

Accessing Sort Options:

Sort controls are typically located in the toolbar or View menu. Common access methods:

• Click the "Sort by" dropdown in the toolbar
• Use View → Sort By → [option]
• Right-click the column headers (if in table view)
• Use keyboard shortcuts (if configured)

Changing Sort Order:

Select your desired sort criterion from the dropdown or menu. The library view updates instantly to reflect the new order. An indicator typically shows which column is currently sorted and in which direction (ascending/descending).

Reversing Sort Direction:

Most sort options have two directions (A-Z vs Z-A, newest vs oldest). Click the column header or sort button again to reverse direction. For example, clicking "Year" once sorts newest-first; clicking again sorts oldest-first.

Combining Sort with Search:

Sorting works on whatever papers are currently visible. If you've searched for "climate change," sorting by year shows climate change papers chronologically. If you've searched for "author:smith," sorting by year shows Smith's papers chronologically.

Sort Order Details And Behavior:

Multi-level Sorting:

When papers have identical values for the primary sort criterion, LibrAIry applies secondary sorting. For example:

• Sorting by author → Papers by same author are sub-sorted by year
• Sorting by year → Papers from same year are sub-sorted by title
• Sorting by journal → Papers from same journal are sub-sorted by year

This ensures consistent, predictable ordering even when primary sort values match.

Handling Missing Data:

Papers with missing metadata are typically sorted to the end:

• Sorting by author: Papers without author information appear last
• Sorting by year: Papers without years appear last
• Sorting by journal: Papers without venue information appear last

This prevents incomplete records from cluttering the top of sorted lists.

Case Insensitivity:

Sorting is case-insensitive. "Smith" and "smith" are treated identically. Numbers sort numerically when appropriate (1, 2, 10 rather than 1, 10, 2).

Persistence:

Your sort preference typically persists between sessions. If you sort by year and close LibrAIry, it will still be sorted by year when you reopen it. This saves you from repeatedly re-sorting.

Practical Sorting Scenarios:

Finding Recent Additions:

Task: See what papers you imported this week

Action: Sort by "Date Added - Newest First"

Result: Most recent imports appear at top

Author-Focused Review:

Task: Review all papers by a particular author in chronological order

Action: Search for "author:lecun", then sort by "Year - Oldest First"

Result: LeCun's papers appear chronologically, showing evolution of work

Journal Analysis:

Task: Identify which journals you've collected most from

Action: Sort by "Journal A-Z"

Result: Papers group by journal, making it easy to count papers per venue

Systematic Reading Plan:

Task: Read papers chronologically to understand field development

Action: Search for topic, then sort by "Year - Oldest First"

Result: Papers appear in historical order, showing how ideas evolved

Priority Reading List:

Task: Identify the most important papers for your current work

Action: Search for key topic, sort by "Relevance"

Result: Most relevant papers appear first, then decreasing relevance

Identifying Collection Gaps:

Task: Find gaps in your year coverage

Action: Sort by "Year - Newest First"

Result: Scan years to spot missing periods (e.g., jump from 2019 to 2022)

Duplicate Detection:

Task: Find accidentally imported duplicates

Action: Sort by "Title A-Z"

Result: Identical or nearly identical titles appear adjacent

Combining Sort With Other Features:

Sort + Search + Selection:

Workflow: Search for "climate adaptation", sort by year (newest first), select top 10 papers, synthesize

Outcome: Literature review of 10 most recent climate adaptation papers

Sort + Tags:

Workflow: Filter by tag "methodology", sort by author

Outcome: See which authors you've collected methodological papers from

Sort + Export:

Workflow: Sort by year (oldest first), export to CSV

Outcome: Chronologically ordered bibliography for appendix

Sort + Chat:

Workflow: Search topic, sort by relevance, select top 20, open Chat

Outcome: Discuss the most relevant papers on topic with AI

Tips For Effective Sorting:

Match Sort to Task: Choose the sort that makes your current task easiest. Reading chronologically? Sort by year. Looking for a specific author? Sort by author.

Re-sort Frequently: Don't stick with one sort order. Switch as your task changes. Sorting is instant and costs nothing.

Combine with Search: Sorting is most powerful when applied to search results. "Climate papers by year" is more useful than "all papers by year."

Use Newest-First as Default: Sorting by "Date Added - Newest First" keeps recent additions visible, ensuring you don't forget about newly imported papers.

Check Sort Indicator: Always know which sort is active. Forgetting you're sorted by journal when you wanted year can be confusing.

Reverse for Different Perspectives: Oldest-first vs newest-first, A-Z vs Z-A—reversing direction often reveals different insights.

Sort Limitations:

Single Primary Criterion: LibrAIry sorts by one primary criterion at a time. You can't simultaneously sort by author AND year as co-equal criteria (though secondary sorting applies automatically).

Depends on Metadata Quality: Sorting requires good metadata. Papers with missing years can't be properly sorted by year. Run "Extract Metadata" to improve sorting accuracy.

No Custom Sort Orders: You can't define custom sort orders (e.g., "sort by my personal importance rating"). Sorting uses LibrAIry's built-in criteria only.

Right CLick

What Is The Right-Click Menu:

The right-click context menu provides quick access to common operations you can perform on papers in your library. Instead of navigating through menu bars, simply right-click any paper to reveal a menu of available actions.

The context menu adapts based on your selection. When you right-click a single paper, you'll see all available actions including those specific to individual papers. When you've selected multiple papers, the same menu appears, and batch-applicable actions will operate on all selected items.

Right-clicking is one of the fastest ways to select papers for synthesis, edit metadata, export files, inspect extracted text, or delete papers from your library.

Accessing The Right-Click Menu:

On Windows and Linux:

Right-click any paper in the library view to open the context menu. The menu appears at your mouse cursor position.

On Mac:

Control-click (hold Control and click) or right-click with a two-finger click on the trackpad.

On Selected Papers:

If you've already selected one or more papers (by clicking to highlight them in blue), you can right-click any of the selected papers. Actions that support batch operations will apply to all selected items.

Selection Behavior:

If you right-click a paper that isn't currently selected, LibrAIry automatically selects that paper before showing the menu. If you right-click a paper that's already part of a multi-selection, the menu operates on the entire selection.

Available Menu Actions:

The right-click menu contains the following actions, listed in order of appearance:

1. Select for Synthesis

Marks the selected paper(s) for inclusion in the next Synthesis operation. When you select papers for synthesis using this menu, they receive a visual indicator (checkmark in the selection column) that persists even when you change your visual selection in the library.

How it works:

• Single selection: Marks that paper for synthesis
• Multiple selection: Marks all selected papers for synthesis
• If selecting 4 or more papers, displays a warning about AI resource consumption
• Papers remain marked until you run synthesis or clear the selection

Use case: Building a specific collection of papers for automated literature review generation, separate from your current visual selection. You can search, tag, or browse your library while maintaining your synthesis selection.

2. Inspect Extracted Text (single paper only)

Opens a new window displaying the raw text extracted from the PDF file. This shows you exactly what text LibrAIry was able to extract from the PDF, which is useful for diagnosing extraction quality issues.

How it works:

• Only appears when exactly one paper is selected
• Extracts text using LibrAIry's PDF text extraction
• Opens in a read-only scrollable text window
• Displays extraction results even if initial metadata extraction failed

Use case: Checking if a PDF is readable (not scanned), verifying text extraction quality, diagnosing why metadata extraction failed, or examining what text is available for AI features (Chat, Synthesis).

3. View Article Online (single paper only)

Opens the paper's online version in your web browser. This uses the paper's URL if available in metadata, or constructs a DOI link if a DOI is present.

How it works:

• Only appears when exactly one paper is selected
• First checks for 'url' field in metadata
• If no URL, checks for DOI and opens https://doi.org/{doi}
• If neither URL nor DOI exists, displays info message
• Opens in your default web browser

Use case: Accessing the publisher's webpage for the paper, downloading supplementary materials, checking for errata or retractions, verifying citation information, or accessing the paper if your local PDF is corrupted.

4. Enrich Metadata (Full Text)

Re-runs metadata extraction on selected paper(s) using Grobid's full-text processing. This is more thorough than the initial extraction and can recover metadata that was missed during the first pass.

How it works:

• Marks selected papers as unprocessed
• Opens the indexing view showing extraction progress
• Runs Grobid extraction in a background thread
• Processes each selected paper sequentially
• Updates metadata in the library after extraction

Use case: Fixing papers with missing or incorrect metadata, processing papers that were added before Grobid was properly configured, extracting additional fields like abstract or keywords that weren't captured initially, or improving metadata quality for important papers.

Warning: This overwrites existing metadata. If you've manually edited metadata for a paper, enrichment will replace your edits unless the paper is marked as user-modified.

5. ✏️ Edit Metadata

Opens a dialog window where you can manually edit all metadata fields for the selected paper. This is the primary way to correct errors or add missing information that automated extraction couldn't capture.

How it works:

• Opens when one or more papers are selected (but edits only the first paper if multiple selected)
• Displays editable fields: Title, Authors, Year, Journal, Volume, Pages, DOI
• Includes a larger text area for Abstract
• Saves changes to the library database
• Marks the paper as "user-modified" to prevent automatic re-extraction
• Sets extraction status to "[Modified Metadata]"

The metadata dialog includes:

• Title field (single line)
• Authors field (single line, comma-separated)
• Year field (single line)
• Journal field (single line)
• Volume field (single line)
• Pages field (single line)
• DOI field (single line)
• Abstract field (multi-line scrollable text area)

Use case: Correcting author names with wrong capitalization, adding missing DOIs, fixing incorrect years, completing partial abstracts, or correcting any metadata that automated extraction got wrong.

Protection: Papers edited through this dialog are marked as user-modified and won't be overwritten by future automatic metadata extraction, preserving your manual corrections.

6. Export Files...

Opens an export dialog that lets you export selected papers as PDF files, bibliographic data (BibTeX, RIS), or both.

How it works:

• Opens a dialog showing export format options
• Allows choosing destination folder
• Exports selected papers in chosen format(s)

Export options:

• PDF Files only: Copies PDF files to chosen folder
• BibTeX File (.bib) only: Creates export_references.bib with bibliographic data
• EndNote/Zotero (.ris) only: Creates export_endnote.ris for reference managers
• Complete Package (PDF + BibTeX + RIS): Exports everything

The export dialog displays the number of items being exported and asks you to choose a destination folder. After export, it shows a summary of what was created.

BibTeX format: Creates citation keys from first author's name and year (e.g., Smith2023)

RIS format: Standard EndNote/Zotero format with all available metadata fields

Use case: Sharing papers with colleagues, importing to reference managers (Zotero, Mendeley, EndNote), creating backup copies of specific papers, generating bibliography files for LaTeX documents, or archiving papers for a specific project.

7. Delete

Removes the selected paper(s) from your LibrAIry library. This deletes the metadata entry but does not delete the actual PDF file from your disk.

How it works:

• Removes library entry from the database
• Removes the item from the visual display
• Does NOT delete the PDF file from disk (file remains in original location)
• No confirmation dialog (direct deletion)

Use case: Removing irrelevant papers from your library, cleaning up duplicates, managing library size, or removing papers you no longer need to track.

Important: This action removes papers from LibrAIry's database but preserves the PDF files. If you want to completely delete the PDFs, you'll need to manually delete them from your file system after removing them from the library.

Recovery: Since PDF files aren't deleted, you can re-import papers if you delete them by mistake.

Menu Structure And Behavior:

Menu Order:

1. Select for Synthesis
2. Inspect Extracted Text (single paper only)
3. View Article Online (single paper only)
4. Enrich Metadata (Full Text)
5. --- separator ---
6. ✏️ Edit Metadata
7. Export Files...
8. --- separator ---
9. Delete

Dynamic Items:

The menu contains two items that only appear when exactly one paper is selected:

• "Inspect Extracted Text" (inserted at position 2)
• "View Article Online" (inserted at position 3)

When multiple papers are selected, these two items are hidden, and the menu shows only the batch-compatible actions.

Separators:

Two horizontal separators visually group related actions:

• Separator after metadata operations, before editing
• Separator after export, before deletion

This grouping makes it easier to find the action you need.

Practical Workflows Using Right-Click:

Workflow 1: Building a Synthesis Set

1. Search for papers on your research topic (e.g., "climate adaptation")
2. Review the search results
3. Right-click first relevant paper → "Select for Synthesis"
4. Right-click second relevant paper → "Select for Synthesis"
5. Continue marking papers (checkmark appears on each)
6. When ready, go to Tools → Synthesis
7. Synthesis automatically uses all papers marked via right-click

This workflow lets you build your synthesis collection gradually while browsing, searching, or reviewing your library, without losing your selection.

Workflow 2: Fixing Metadata for Important Papers

1. Notice a paper has missing abstract or incorrect author
2. Right-click the paper → "✏️ Edit Metadata"
3. Correct the fields in the dialog
4. Click "💾 Save Changes"
5. Paper is now marked as user-modified and won't be auto-extracted again

This protects your manual corrections from being overwritten.

Workflow 3: Quality Check on Scanned PDFs

1. Import a batch of PDFs
2. Notice some have minimal metadata (possible scans)
3. Right-click suspicious paper → "Inspect Extracted Text"
4. Review extracted text quality
5. If text is gibberish or empty → PDF is scanned, metadata extraction will fail
6. If text is readable → Right-click → "Enrich Metadata (Full Text)" to try again

This helps identify which PDFs are scanned (image-based) vs. readable.

Workflow 4: Exporting Papers for Collaboration

1. Search or filter to find papers for a specific project
2. Select all relevant papers (Ctrl+Click or Shift+Click)
3. Right-click any selected paper → "Export Files..."
4. Choose "Complete Package (PDF + BibTeX + RIS)"
5. Select destination folder
6. Share the exported folder with colleagues

Recipients get PDFs plus bibliography files for their reference managers.

Workflow 5: Accessing Publisher Versions

1. Reading a paper and want to check for supplementary materials
2. Right-click the paper → "View Article Online"
3. Browser opens to publisher's page
4. Download supplementary data, check for corrections, or access cited papers

Useful when your PDF doesn't include all content from the online version.

Keyboard Shortcuts:

The right-click menu itself doesn't have keyboard shortcuts, but you can use keyboard navigation once the menu is open:

• Arrow Keys: Navigate up/down through menu items
• Enter: Execute the highlighted menu item
• Escape: Close the menu without executing any action

These shortcuts make the menu accessible even without a mouse.

Tips For Efficient Right-Click Usage:

Select Before Right-Clicking: When working with multiple papers, select them all first (Ctrl+Click or Shift+Click), then right-click once. This is faster than right-clicking each paper individually.

Use for Synthesis Selection: The "Select for Synthesis" feature is one of the most powerful uses of right-click. It lets you mark papers gradually while browsing, without losing your working selection.

Check Extracted Text First: Before re-running metadata extraction on a paper, use "Inspect Extracted Text" to verify the PDF is readable. This saves time on scanned PDFs where extraction will fail anyway.

Edit Metadata for Key Papers: For papers you cite frequently, use "✏️ Edit Metadata" to ensure perfect accuracy. The user-modified flag prevents future overwrites.

Export Before Major Changes: Before deleting papers or reorganizing your library, use "Export Files..." to create backups of important papers.

Limitations And Notes:

Single vs. Multiple Selection:

• "Inspect Extracted Text" and "View Article Online" only work with single selections
• All other actions work with both single and multiple selections
• If multiple papers are selected, these single-paper actions are hidden from the menu

No Undo for Delete:

• Deleting papers from the library is immediate with no confirmation
• However, PDF files remain on disk, so you can re-import if needed
• Be careful when deleting, especially with multiple selections

User-Modified Flag:

• Papers edited via "✏️ Edit Metadata" are marked as user-modified
• This prevents "Enrich Metadata (Full Text)" from overwriting your changes
• To allow re-extraction, you'd need to manually clear the user-modified flag in the JSON

Export Limitations:

• Export only copies files; it doesn't move them
• BibTeX citation keys are auto-generated (FirstAuthorYear format)
• RIS export includes all available metadata but may be incomplete if metadata is poor

Online Access Requires URL/DOI:

• "View Article Online" only works if paper has URL or DOI in metadata
• Papers without this information will show an info message
• You can add missing DOIs via "✏️ Edit Metadata"

TROUBLESHOOTING:

Right-click menu doesn't appear:

• Ensure you're clicking on a paper row, not empty space
• Try clicking the paper first to select it, then right-clicking
• Check if LibrAIry window has focus (click it first)

"View Article Online" shows "No URL or DOI":

• The paper's metadata is missing both URL and DOI fields
• Use "✏️ Edit Metadata" to add the DOI manually
• Search for the paper online to find its DOI

"Enrich Metadata" doesn't improve results:

• The PDF may be scanned (image-based, not text)
• Use "Inspect Extracted Text" to check if text extraction works
• If text is gibberish/empty, you'll need to edit metadata manually

Can't select multiple papers for batch operations:

• Make sure you're using Ctrl+Click (Windows/Linux) or Cmd+Click (Mac)
• Or use Shift+Click to select a range of consecutive papers
• The blue highlight shows which papers are selected

Key Features Summary - Right-Click Menu:

• Select for Synthesis: Mark papers for automated literature review (batch-compatible)

• Inspect Extracted Text: View raw PDF text extraction (single paper only)

• View Article Online: Open paper's online version via URL/DOI (single paper only)

• Enrich Metadata (Full Text): Re-run Grobid extraction for better metadata (batch-compatible)

• Edit Metadata: Manually correct/add metadata with user-modified protection (single paper)

• Export Files: Export PDFs and/or bibliographic data (BibTeX, RIS) (batch-compatible)

• Delete: Remove papers from library (preserves PDF files) (batch-compatible)

• Context-Aware: Menu adapts based on single vs. multiple selection

• Fast Access: Quicker than navigating menu bars for common operations

• Batch Operations: Most actions support multiple selected papers

Comparison With Other Interfaces:

Right-Click vs. Menu Bar:

• Right-click is faster for paper-specific operations
• Menu bar is better for application-level settings
• Both provide access to metadata editing and export

Right-Click vs. Double-Click:

• Double-click opens the PDF file
• Right-click opens the action menu
• Use double-click for quick reading, right-click for operations

Right-Click vs. Toolbar:

• Toolbar shows most common global actions (Import, Search, Synthesis)
• Right-click shows paper-specific actions
• Toolbar is more visual (icons), right-click is more comprehensive

LibrAIry's Synthesis feature transforms the tedious process of writing literature reviews into an automated, AI-powered workflow. Instead of spending days or weeks manually reading dozens of papers, extracting key findings, and synthesizing them into coherent sections, Synthesis does this work for you in minutes.

The Synthesis feature analyzes your selected papers and generates structured, well-organized literature review sections that you can directly use in your thesis, dissertation, or research paper. It doesn't just summarize individual papers—it identifies themes across your collection, compares methodologies, synthesizes findings, and presents everything in a properly formatted document ready for your writing.

Think of Synthesis as your AI research assistant that has read all your papers, identified the key themes and patterns, and written draft literature review sections that capture the state of the field. You provide the papers and guidance on what aspects to focus on; Synthesis provides publication-ready text organized into clear sections with proper structure.

The output is a complete Word document (.docx) with formatted headings, paragraphs, and optionally a reference list, which you can immediately open, edit, and incorporate into your work. This dramatically accelerates the literature review process while ensuring you don't miss important themes or connections across your collection.

What Synthesis Creates:

Synthesis generates structured literature review documents with multiple sections, each focusing on a different aspect of your research topic. A typical synthesis output includes:

Introduction Section that provides an overview of the research field, explains why the topic matters, and outlines the scope of the literature being reviewed. This sets the context for readers unfamiliar with your research area.

Thematic Sections that organize findings around major themes identified across your papers. For example, a synthesis on climate change impacts might include sections on "Effects on Ecosystems," "Economic Consequences," and "Mitigation Strategies." Each section synthesizes what multiple papers say about that theme.

Methodological Overview that compares and contrasts the research methods used across studies. This might discuss which statistical approaches are most common, what data sources researchers use, or how different methodological choices affect findings.

Key Findings and Conclusions that summarize the current state of knowledge, identify areas of consensus and disagreement, and highlight gaps that future research should address.

Optional Reference List that provides properly formatted citations for all papers discussed in the synthesis, making it easy to verify sources and maintain academic integrity.

All sections are written in clear, academic prose suitable for direct inclusion in research papers, with smooth transitions between ideas and proper attribution of findings to sources.

How Synthesis Works:

The synthesis process follows a systematic workflow designed to produce high-quality, comprehensive literature reviews:

Step 1: Paper Selection. You choose which papers to include in the synthesis. This can be done by selecting papers in the main library view (clicking to highlight them in blue) or by using the checkbox selection feature. The quality of your synthesis depends heavily on selecting relevant, high-quality papers that address your research question.

Step 2: Configuration. You specify what type of synthesis you want through several options:

The Number of Sections determines how many thematic sections the synthesis will include. More sections provide finer-grained organization but may be less cohesive. Typical syntheses use 3-5 sections. For instance, a 4-section synthesis might cover background, methodologies, findings, and future directions.

The Depth of Analysis controls how thoroughly each paper is analyzed. "Abstract-only" mode is faster and works even with scanned PDFs, using only the abstracts and conclusions LibrAIry has extracted. "Full text" mode reads entire PDFs for deeper analysis but takes longer and requires readable (non-scanned) PDFs.

Include References adds a properly formatted reference list at the end of the document, with all cited papers listed in alphabetical order or citation order, depending on your preference.

Step 3: AI Processing. Once you start the synthesis, the AI analyzes all selected papers to identify themes, extract key findings, compare methodologies, and organize information into coherent sections. This involves multiple AI calls: first to identify overarching themes across papers, then to generate content for each section by synthesizing relevant information from multiple sources.

Step 4: Document Generation. The AI's output is formatted into a professional Word document with proper headings, paragraph structure, and optionally a reference list. The document is saved to your specified location and automatically opened in Microsoft Word (if available) or your default word processor.

Step 5: Review and Editing. You review the generated synthesis, verify that it accurately represents the literature, add your own insights, and refine the writing to match your voice and the specific requirements of your project.

Synthesis Options Explained:

Number of Sections (Recommended: 3-5)

This determines how the synthesis organizes information. More sections allow for finer distinctions between themes but may create fragmentation if you don't have enough papers to support each section adequately.

For a small collection (5-10 papers): Use 2-3 sections to maintain cohesion and ensure each section has sufficient content.

For a medium collection (10-30 papers): Use 3-5 sections to organize diverse themes while keeping each section substantive.

For a large collection (30+ papers): Use 5-7 sections to prevent any single section from becoming overwhelming, though you may want to create multiple smaller syntheses instead.

Common section structures include:

• 3 sections: Background/Context, Key Findings, Conclusions/Gaps
• 4 sections: Introduction, Methodological Approaches, Major Findings, Future Directions
• 5 sections: Historical Context, Theoretical Frameworks, Empirical Studies, Contradictions/Debates, Research Needs

Analysis Depth: Abstract-Only vs. Full Text

Abstract-only analysis uses the metadata LibrAIry has already extracted (titles, authors, abstracts, and conclusions). This is faster, works reliably even with scanned PDFs, and is often sufficient for getting a good overview of the field. Abstract-only mode typically completes in 2-5 minutes for 20 papers.

Full text analysis reads the complete PDF of each paper, including methodology sections, detailed results, tables, figures captions, and discussion sections. This provides much richer synthesis with specific details, exact statistical values, and nuanced arguments that don't appear in abstracts. However, full text mode takes significantly longer (10-30 minutes for 20 papers) and requires readable (non-scanned) PDFs.

When to use abstract-only:

• Quick literature reviews for background understanding
• Initial exploration of a new research area
• When many papers are scanned or low-quality PDFs
• When you need results quickly

When to use full text:

• Comprehensive systematic reviews for publication
• When you need methodological details
• For comparing specific statistical approaches or results
• When abstract-only synthesis seems too superficial

Include References

When enabled, Synthesis adds a "References" section at the end of the document with properly formatted citations for all papers mentioned in the text. This saves you from manually creating a bibliography and ensures all sources are properly attributed.

The reference format follows standard academic citation style (typically APA-like), with author names, year, title, journal/conference, and other bibliographic details extracted from LibrAIry's metadata.

Practical Usage Scenarios:

Thesis/Dissertation Literature Review: Select all papers relevant to your research topic (typically 30-80 papers for a PhD thesis chapter), configure synthesis for 5-6 sections covering different aspects of the field, use full text mode for depth, and generate a comprehensive literature review that serves as the foundation of your Chapter 2.

Research Paper Background Section: For a focused research paper, select 10-20 highly relevant papers, use 2-3 sections to cover background and key findings, and generate a concise literature review that contextualizes your study within existing research.

Grant Proposal Literature Review: Select papers demonstrating the importance and novelty of your proposed research, use 3-4 sections highlighting the problem, existing approaches, gaps, and the need for your work, and generate compelling justification for your project.

Systematic Review: For formal systematic reviews, select all papers meeting your inclusion criteria (potentially 50+ papers), use 6-8 sections organized by research questions, enable full text mode for comprehensive analysis, and generate the core of your systematic review manuscript.

Rapid Field Survey: When entering a new research area, select 15-25 foundational and recent papers, use abstract-only mode for speed, generate 3-4 sections covering fundamentals, current state, and open questions, and get oriented in the field within an hour.

Comparative Analysis: Select papers using different methodological approaches (e.g., 10 quantitative studies and 10 qualitative studies), configure sections to compare methodologies, findings, and limitations, and generate a synthesis that illuminates how different approaches yield different insights.

Customization And Control:

While Synthesis operates automatically once started, you maintain control through careful paper selection and configuration:

Paper Selection Strategy is crucial. Include only papers directly relevant to your synthesis goals. Too many tangentially related papers will dilute the focus. Aim for quality over quantity—20 highly relevant papers produce better synthesis than 50 loosely related ones.

Section Planning should align with your writing goals. Think about what organizational structure serves your readers best. If writing for a specialized audience, you might skip background sections and focus on recent advances. For a general audience, include more contextual sections.

Iterative Refinement is often effective. Generate an initial synthesis with abstract-only mode to see what themes emerge, then if needed, run a second synthesis with full text mode focusing on specific aspects that need deeper treatment.

Combining with Manual Writing works well. Use Synthesis to generate draft sections, then rewrite in your own voice, add critical analysis, or reorganize to fit your specific argument structure. Synthesis provides the raw material; you shape it into your final narrative.

Output Format And Structure:

Synthesis generates Microsoft Word (.docx) files with professional formatting:

Document Structure includes a title at the top (typically "Literature Review Synthesis" or similar), followed by sequential sections with clear headings. Each section contains multiple paragraphs of synthesized content, typically 300-800 words per section depending on the number of papers and depth of analysis.

Heading Hierarchy uses Heading 1 style for section titles (e.g., "Methodological Approaches in Climate Research") and optionally Heading 2 for subsections if the content naturally divides further.

Paragraph Style uses standard body text with proper spacing, justified or left-aligned depending on system defaults. Paragraphs typically contain 3-6 sentences, with smooth transitions between ideas.

Citations and Attributions appear in-text, typically mentioning authors and years when referencing specific findings. For example: "Smith et al. (2020) found that..." or "Recent studies have shown increased prevalence (Jones, 2019; Lee, 2021)."

Reference List (if enabled) appears as the final section with "References" as a Heading 1, followed by alphabetically ordered citations in standard academic format.

The document is immediately editable in Word, allowing you to adjust formatting, add comments, track changes, or integrate with larger documents.

Integration With Other Features:

Synthesis works seamlessly with LibrAIry's other capabilities:

Search and Filtering: Use LibrAIry's search to find papers on a topic, filter by year or keyword, then synthesize the filtered collection. This ensures your synthesis covers a well-defined subset of the literature.

Tags and Collections: Tag papers by theme or methodology, then synthesize papers with specific tags. For instance, synthesize all papers tagged "qualitative methods" to compare qualitative approaches across studies.

Metadata Quality: Better metadata from successful Grobid extraction improves synthesis quality. If abstracts are missing or poorly extracted, synthesis quality suffers. Running "Extract Metadata" before synthesis can help.

Chat Feature: Use Chat to explore your papers interactively first, identifying key themes and questions. Then run Synthesis to generate formal literature review sections on those themes.

Multiple Syntheses: Create separate syntheses for different aspects of your research. For example, one synthesis on theoretical frameworks, another on methodologies, and a third on empirical findings, then combine them into different chapters.

When To Use Synthesis Vs. Chat:

Use Synthesis when you want to:

• Generate formal literature review sections for writing
• Create structured, organized summaries of the field
• Produce publication-ready text for papers or theses
• Compare multiple studies systematically
• Create comprehensive overviews covering many papers
• Get properly formatted Word documents
• Have a reference list automatically generated

Use Chat when you want to:

• Ask specific questions about your papers
• Explore your collection interactively
• Find particular methodologies or findings quickly
• Understand relationships between studies
• Get quick answers without generating documents
• Iterate rapidly through different questions
• Work conversationally rather than generating final outputs

Limitations And Considerations:

Processing Time: Full text synthesis can take 15-30 minutes for 30 papers, sometimes longer with many/large papers. Abstract-only mode is faster but less detailed. Plan accordingly, especially for large collections.

Paper Selection Quality: Synthesis quality depends entirely on which papers you select. Irrelevant or low-quality papers will dilute the synthesis. Carefully curate your collection before synthesizing.

AI-Generated Content: While synthesis produces high-quality academic prose, it's AI-generated and should be reviewed, verified, and edited before publication. Always check that claims accurately represent the source papers.

Citation Accuracy: The AI strives to accurately attribute findings, but may occasionally misattribute or miss nuances. For critical research, verify key claims against the original papers.

Language and Voice: Synthesis writes in formal academic style, which may not match your personal voice. You'll likely want to rewrite some sections to achieve stylistic consistency with your other writing.

Scanned PDFs: Full text mode cannot extract text from scanned or image-based PDFs. These papers will only use their abstracts even in full text mode. The system will notify you if this occurs.

Requires AI Service: Synthesis requires either a working internet connection (for cloud AI services like Google Gemini) or a local AI service (Ollama) running on your computer. Configure in File → Network & AI Settings.

Quality Improvement Tips:

Select Cohesive Papers: Choose papers that genuinely relate to a unified research question. Random collections produce disjointed syntheses.

Use Consistent Scope: If synthesizing methodological papers, include only methodological papers. Mixing theoretical and empirical papers without clear organization confuses the synthesis.

Provide Good Metadata: Ensure papers have complete abstracts and conclusions. Run "Extract Metadata" on any papers showing incomplete information before synthesizing.

Start Small: For your first synthesis, try 10-15 papers with 3 sections and abstract-only mode. This gives quick results you can evaluate before investing in larger syntheses.

Iterate and Refine: Generate an initial synthesis, review it to see what works and what's missing, adjust your paper selection or configuration, and synthesize again if needed.

Edit Actively: Don't expect perfect output. Plan to spend time editing, reorganizing, adding your own analysis, and refining the AI's draft into your final text.

Verify Citations: Spot-check that specific findings are correctly attributed. If the synthesis claims "Johnson (2020) found X," verify that Johnson actually found X.

Combine Multiple Syntheses: For very large projects, create separate syntheses for different themes or time periods, then manually integrate them. This is often better than one massive synthesis.

What is AI Chat ?

OVERVIEW (Narrative):

LibrAIry's Chat feature transforms your PDF library into an intelligent research assistant. Instead of manually reading through dozens of articles to find specific information, you can simply ask questions in natural language and receive instant, context-aware answers drawn directly from your papers.

The Chat feature uses AI to understand your questions and search through your entire library—or specific selected articles—to provide accurate, cited responses. Whether you're looking for methodologies used across multiple studies, comparing findings from different papers, or trying to understand complex concepts, the Chat feature acts as your personal research assistant that has read every paper in your collection.

Think of it as having a knowledgeable colleague who has thoroughly reviewed all your papers and can instantly recall relevant information, synthesize findings across multiple sources, and help you discover connections you might have missed.

Two Modes Of Operation:

The Chat feature offers two distinct modes to match different research needs:

Questions on Articles Mode is the primary research mode where the AI acts as your library expert. In this mode, you can ask questions about your papers, and the AI will search through your selected articles to provide answers based on their content. The AI has access to all the metadata LibrAIry has extracted (titles, authors, abstracts, conclusions) and can optionally read the full text of PDFs when you need deeper analysis. This mode is perfect for literature reviews, finding methodologies, comparing results across studies, or understanding what your collection says about specific topics.

General Questions Mode switches the Chat to a standard AI assistant without access to your library. In this mode, you can ask general questions about research methods, statistics, writing advice, or any other topic. The AI responds based on its general knowledge rather than your specific papers. This mode is useful when you need help with concepts, want to understand terminology before searching your papers, or need general research guidance that doesn't require reading your library.

How It Works - Questions On Articles Mode:

When you ask a question in Articles mode, LibrAIry follows an intelligent process to find and present relevant information from your papers.

First, the system identifies which articles are relevant to your question. You control this selection in two ways: you can either select specific articles before opening Chat (by clicking them in the main library view to highlight them in blue, or using checkboxes), or you can reference specific articles within your question using the #number syntax. For example, typing "What methodology did #5 use?" will direct the AI to focus specifically on article number 5.

Once the relevant articles are identified, the AI analyzes their content to answer your question. By default, the system works with metadata—titles, authors, years, journals, abstracts, and conclusions—which provides fast responses and works even with scanned PDFs. However, when you enable "Read Full Text (PDF)" mode, the AI will extract and analyze the complete text of each article, allowing for much deeper analysis at the cost of longer processing time.

The AI then formulates an answer by synthesizing information across all selected papers. It doesn't just copy text from your articles; instead, it understands your question, identifies relevant information, and presents a coherent answer that may draw from multiple sources. When information comes from specific papers, the response will naturally reference them, helping you trace findings back to their sources.

Article Selection Methods:

LibrAIry provides flexible ways to choose which articles the Chat should analyze:

Visual Selection (Recommended): Click articles in the main library view to highlight them in blue. Selected articles remain highlighted when you open Chat, making it easy to see exactly which papers will be analyzed. You can select multiple articles by holding Ctrl (Windows/Linux) or Cmd (Mac) while clicking. This visual approach makes it clear which papers you're working with.

Checkbox Selection: Right-click articles and choose "Select for Synthesis" to mark them with checkboxes. These checkboxes persist across sessions and can be useful for building collections of related papers over time. However, the visual selection (blue highlighting) is generally more intuitive for Chat usage.

In-Chat References: Use the #number syntax within your questions to reference specific articles. For example, "Compare the methodology in #12 with #18" or "Summarize #7". This is perfect when you want to ask about specific papers without leaving the Chat window.

Combined Approach: All three methods work together. You can have some articles visually selected, others marked with checkboxes, and still reference additional specific articles using # syntax. The AI will consider all of them when formulating its answer.

Abstract-Only Vs Full Text Mode:

The Chat feature offers two levels of document analysis, each suited to different research scenarios.

Abstract-Only Mode (Default - Faster) analyzes titles, authors, abstracts, and conclusions from your papers. This mode provides quick responses because it processes less text, and it works reliably even with scanned PDFs since LibrAIry has already extracted these metadata fields. Abstract-only mode is ideal for getting quick overviews, finding papers on specific topics, checking what methods were used, or comparing high-level findings across multiple studies. Most research questions can be answered effectively using just abstracts and conclusions, making this the recommended starting point.

Full Text Mode (Slower but Comprehensive) extracts and analyzes the complete text of each PDF, including methodology sections, detailed results, tables, figures captions, and discussion sections. This deeper analysis takes significantly longer because the AI must read potentially dozens of pages per article. However, full text mode is essential when you need specific details that aren't in abstracts—like exact statistical values, detailed procedures, or nuanced arguments in the discussion section. Enable this mode by checking "Read Full Text (PDF) - Slower" at the bottom of the Chat window.

Important consideration: Full text extraction requires readable PDFs. Scanned articles (old photocopied papers) may not extract properly, and the system will fall back to using abstracts only. The AI will notify you if full text extraction fails for any articles.

Practical Usage Scenarios:

Literature Review Questions: Ask broad questions like "What are the main findings about climate change impacts on coral reefs?" across your entire selected collection. The AI will synthesize information from all relevant papers, helping you identify trends, consensus views, and conflicting findings.

Methodology Extraction: Questions like "What statistical methods were used in these studies?" or "How did researchers measure participant engagement?" help you quickly catalog methodologies across your collection without manually reading each paper's methods section.

Cross-Study Comparison: Ask the AI to compare findings: "How do the results in #3 and #7 differ?" or "Which studies found a positive effect and which found no effect?" This is particularly powerful for systematic reviews.

Concept Clarification: When you encounter unfamiliar terms in your reading, switch to General mode and ask "What is hierarchical linear modeling?" before switching back to Articles mode to find papers using that method.

Focused Deep Dives: Select a single article and enable Full Text mode to ask detailed questions: "What were the exact inclusion criteria?" or "What did the authors say about limitations?" This is faster than manually searching through a 30-page PDF.

Building Arguments: Use Chat to gather supporting evidence: "What papers discuss the relationship between X and Y?" or "Which studies support the hypothesis that...?" The AI helps you find relevant passages and papers for your own writing.

Conversation History And Context:

The Chat feature maintains a conversation history during each session, allowing for natural, contextual interactions. This means you can ask follow-up questions without repeating context. For example, after asking "What methodologies were used in these papers?", you can simply follow up with "Which of those would work for a small sample size?" and the AI understands you're still asking about the previously discussed methodologies.

This contextual awareness makes the Chat feel more like a discussion with a knowledgeable colleague than a series of isolated searches. You can refine questions, ask for clarification, or drill deeper into topics through a natural conversation flow.

The conversation history is displayed in the upper panel of the Chat window, showing your questions in blue and the AI's responses below them. This makes it easy to scroll back and review earlier parts of the conversation.

You can save your conversation at any time using the "Save Conversation" button in the menu. This creates a text file containing the entire chat history, which is useful for documentation, sharing findings with colleagues, or keeping a record of your research process.

When you want to start fresh, simply close and reopen the Chat window. Each new Chat session begins with a clean slate, though your article selections are preserved.

Tips For Effective Questions:

Be Specific but Natural: Ask questions as you would to a research assistant. Instead of keywords, use complete questions: "What statistical tests were used?" is better than "statistics tests".

Start Broad, Then Narrow: Begin with overview questions to understand what's in your collection, then ask increasingly specific follow-up questions to drill into details.

Use #References Strategically: When you know you want information from specific papers, reference them directly: "According to #12, what was the sample size?" This focuses the AI's attention and provides faster, more precise answers.

Enable Full Text When Needed: Start with abstract mode for speed. Only switch to full text when you need details that wouldn't be in an abstract—specific numbers, detailed procedures, or nuanced arguments.

Rephrase if Needed: If an answer isn't quite what you wanted, rephrase your question or add clarifying context. The AI maintains conversation history, so you can refine questions based on previous responses.

Verify Critical Information: While the AI is very reliable for finding and summarizing information, always verify critical facts by consulting the original papers. Use Chat to find relevant information quickly, then read the sources yourself for final verification.

Limitations And Considerations:

Scanned PDFs: The full text mode cannot extract text from scanned or image-based PDFs. These papers will only use their abstracts and metadata, even with full text mode enabled. The system will notify you when this occurs.

Response Time: Full text mode can take 10-30 seconds or more per question, depending on how many articles are selected and how long they are. Abstract-only mode typically responds in 3-10 seconds.

AI Service Dependency: The Chat feature requires either a working internet connection (for cloud AI services like Google Gemini) or a local AI service (Ollama) running on your computer. Check your Network & AI Settings if Chat isn't working.

Citation Accuracy: While the AI strives to accurately represent what's in your papers, it may occasionally misinterpret complex arguments or miss nuances. For critical research, always consult the original sources.

Language Support: The AI works best with English-language papers. Papers in other languages may have mixed results depending on the quality of extracted metadata.

What is LibrAIry?

LibrAIry is an AI-powered literature management tool for researchers who want to:

• Organize hundreds of PDF articles easily
• Automatically extract metadata (title, authors, year, journal, etc.)
• Generate BibTeX citations instantly
• Search and filter your papers
• Use AI to synthesize findings

NO programming knowledge required! Just install and use.

LibrAIry uses Grobid (a machine learning tool) to read your PDFs and extract information automatically. You can process papers in minutes instead of hours.

Who Should Use LibrAIry?

Perfect for:

• PhD students managing 100+ papers
• Researchers doing literature reviews
• Academics writing systematic reviews
• Anyone tired of organizing PDFs manually

You don't need to be a programmer - LibrAIry is designed for researchers, not developers!
