Overview

An intelligent document chat application that allows users to interact with their documents through natural language queries. By implementing Retrieval-Augmented Generation (RAG), the system can accurately answer questions based on document content, making information retrieval more intuitive and efficient.

Key Features

  • Retrieval-Augmented Generation (RAG) — Combines retrieval-based methods with generative AI to provide accurate, context-aware answers grounded in document content.
  • LangChain Framework — Utilizes LangChain for building robust LLM applications with document loading, text splitting, embeddings, and vector stores.
  • Vector Database Integration — Uses Pinecone for efficient similarity search and semantic retrieval of relevant document chunks.
  • Natural Language Queries — Users can ask questions in plain language and receive accurate answers extracted from their documents.
  • Multi-Document Support — Handles various document formats (PDF, TXT, DOCX) and enables querying across multiple documents simultaneously.
  • Contextual Understanding — Leverages Hugging Face Transformers for embeddings and language understanding, ensuring high-quality retrieval.

Technical Architecture

  • Framework: LangChain for LLM application orchestration and RAG pipeline
  • Language: Python for backend processing and AI integration
  • Vector Store: Pinecone for scalable vector similarity search
  • Embeddings: Hugging Face Transformers for document and query embeddings
  • Document Processing: LangChain document loaders and text splitters
  • LLM: Integration with various language models for answer generation

Development Period

May 2024 - August 2024

Use Cases

  • Research paper analysis and summarization
  • Personal knowledge base management
  • Document Q&A for study and work materials
  • Information extraction from large document collections
