AI Support Agent with Cited Answers and Human Handoff

An AI support agent that answers only from a store’s help articles, cites the exact section behind each answer, and hands off to a person when it isn’t sure. Built with FastAPI, BM25 retrieval, SQLite, React and TypeScript. A support desk shows conversations and tickets, and a teammate’s reply appears live in the customer’s chat. Key decision: every answer must be backed by a quoted source, otherwise the agent opens a ticket, so it can’t invent policies. Sample data shown.
