Cognito-LangGraph-RAG-Chatbot

This project implements an advanced Retrieval Augmented Generation (RAG) workflow to enhance question-answering accuracy and reduce LLM hallucinations. It leverages LangGraph to create a stateful, multi-step process that includes document retrieval, relevance grading, and web search fallback. Maintained by junfanz1 on GitHub, where it has earned 22 stars from the community.

It's actively developed around chromadb, langchain, langgraph, and is a solid reference for anyone building with these tools.
