ragbase

Completely local RAG. Chat with your PDF documents (with open LLM) and UI to that uses LangChain, Streamlit, Ollama (Llama 3.1), Qdrant and advanced methods like reranking and semantic chunking. Maintained by curiousily on GitHub, where it has earned 128 stars from the community.

It's actively developed around langchain, llama3, llm, and is a solid reference for anyone building with these tools.
