Docchat
Ask questions about your PDFs and get cited answers — no API key, no LLM required.
Docchat (FastAPI) ingests PDFs, splits them into chunks, and answers with a pure-Python BM25 retriever — returning extractive answers and their sources without calling any model. Prefer a real LLM? You can switch one on with a key. It comes with a few fictional sample documents.
