RAG Studio (ragctl) is a powerful command-line tool designed for efficient document processing tailored for Retrieval-Augmented Generation (RAG) systems. It simplifies document ingestion, utilizes advanced Optical Character Recognition (OCR), and performs intelligent chunking, all from the command line.

Key Features

• Universal Document Loading: Supports multiple formats including PDF, DOCX, ODT, TXT, HTML, Markdown, and various image types (JPEG, PNG).
• Advanced OCR Capabilities: Operates with a cascade of OCR engines — EasyOCR, PaddleOCR, and pytesseract — ensuring flexibility and accuracy in text extraction.
• Intelligent Chunking: Utilizes LangChain's recursive text splitter for context-aware chunking, offering different strategies such as semantic, sentence, and fixed token-based splitting.
• Production-Ready Processing: Facilitates batch processing with built-in retry mechanisms and customizable error handling modes, enabling robust workflows.
• Flexible Export Options: Enables output in multiple formats including JSON, JSONL, and CSV, as well as direct ingestion into Qdrant vector stores, ensuring compatibility with various data management systems.

Technical Specifications

Document Processing

• Supported Formats: Handles diverse document types, adapting to content seamlessly.
• OCR Engine Fallbacks: Automatically selects the most effective OCR engine while allowing for manual adjustments.
• Multilingual Support: Supports various languages ensuring global usability.

Chunking Strategies

• Semantic Chunking: Default mode focuses on preserving meaning, with options for sentence and token-based splitting.
• Metadata-Rich Output: Provides comprehensive metadata for each text chunk, including source file and timestamp information, enabling better tracking and usage optimization.

Batch Processing

• Error Handling Options: Includes several modes such as interactive, automatic continuation, auto-stop, and skip functionalities to manage processing efficiently.
• History Tracking: Maintains a detailed history of all operations for future reference and troubleshooting.

Configuration and Customization

• Hierarchical Configuration System: Allows settings to be defined via command line, environment variables, or YAML files, providing convenient management of individual preferences.

Usage Examples

1. Single Document Processing:

   ragctl chunk document.pdf --show
   

2. Batch Processing:

   ragctl batch ./documents --output ./chunks/
   

3. Retrying Failed Cases:

   ragctl retry
   

4. Evaluating Chunk Quality:

   ragctl eval document.pdf --strategies semantic sentence --metrics coverage overlap
