About ai-pdf-chatbot-langchain
mayooear/ai-pdf-chatbot-langchain
AI PDF chatbot agent built with LangChain & LangGraph
Implements dual LangGraph state machines for document ingestion and retrieval—PDF uploads trigger vector embedding storage in Supabase, while queries route through a retrieval graph that decides whether to fetch relevant documents or respond directly. Provides streaming responses via Server-Sent Events from the backend to a Next.js frontend, with LangSmith integration for tracing and debugging each graph execution step.
