RAG Document Assistant

RAG Document Assistant

Upload documents and chat with them via retrieval-augmented generation; sources cited and cached.

About This Project

An intelligent document assistant powered by Retrieval-Augmented Generation (RAG) technology. Users can upload various document formats and interact with their content through natural language queries. The system employs advanced chunking and embedding techniques to process documents, stores them in Pinecone vector database for efficient retrieval, and uses LangChain orchestration to generate accurate, contextual responses. Every answer includes proper source citations, allowing users to verify information. The assistant features hybrid search capabilities combining semantic and keyword-based retrieval, with intelligent caching to optimize performance for frequently asked questions.
