This project is an AI chatbot built on LangChain that allows users to ingest documents (PDFs) and ask questions about them in a conversational interface. It uses OpenAI embeddings and GPT models for language understanding, backed by vector databases (Pinecone and/or ChromaDB) for semantic search and retrieval over the ingested documents. The system supports configurable parameters like temperature and provides an interactive UI for file ingestion and chatting.
