Code is open source at GitHub - tevslin/meeting-reporter: Human-AI collaboration to produce a newstory about a meeting from minutes or transcript

Most examples of Langgraph use are in Jupyter notebooks so not really suitable for deployment to a broad audience. Streamlit solves the UI problem but mating the Streamlit and Langgraph state machines is an interesting problem.
