How it works

  • It searches my writing and checks whether the retrieved passages cover the question.
  • LangGraph handles questions, work reviews and follow-up questions when context is missing.
  • Python checks each quoted passage against the source.
  • FastAPI streams the response to a Streamlit interface.

Limits

The assistant can still misinterpret a source. Demo conversations are stored, so use public examples.
