Document Processor

A modern desktop application for parsing and processing documents (PDF, DOCX, TXT) with intelligent image context extraction.

Built with Rust + Tauri + Svelte for maximum performance and minimal footprint.

Features

• Multi-format parsing: PDF, DOCX, DOC, TXT, RTF
• Image extraction with context: Images are extracted with surrounding text preserved
• Document classification: Automatic detection of document types (umowa, pozew, ustawa, etc.)
• Watch folder: Automatic processing of new documents
• SQLite database: Fast search and organization
• Modern UI: Dark theme, responsive design
• Cross-platform: Linux and Windows support

Installation

Prerequisites

Linux (Ubuntu/Debian)

sudo apt install -y libwebkit2gtk-4.1-dev libappindicator3-dev librsvg2-dev patchelf libssl-dev

Windows

• Install WebView2
• Install Visual Studio Build Tools

Build from source

# Install Rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# Clone and build
cd ~/projects/buildonai/document-processor
npm install
npm run tauri build

Development

npm run tauri dev

Usage

GUI Application

1. Launch the application
2. Drag & drop documents or click to browse
3. Set a "Watch Folder" for automatic processing
4. View processed documents with extracted text and images

Output Structure

Each processed document creates:

processed/<document-id>/
├── document.md        # Human-readable markdown
├── document.json      # Structured data for AI
├── images/
│   ├── img_001.png   # Extracted images
│   ├── img_001.json  # Image metadata + context
│   └── thumb_001.png # Thumbnails
└── original.pdf      # Original file copy

Image Context

Each image includes:

• context_before: 200 characters of text before the image
• context_after: 200 characters after
• position_marker: Page and position reference
• ocr_text: Text extracted from image (if applicable)
• ai_description: AI-generated description (when available)
