AI Chatbot That Answers From a Shop's Own Guide (RAG)

View completed workalfredospizza.github.io
The problem
Small shops get the same questions every day. A normal AI chatbot can invent answers, and a wrong price or rule is a real problem.
What I built
A demo assistant for a fictional e-bike rental shop. It looks for the right part of the shop guide and answers only from that part. It shows the source under each answer and replies in the customer's language. If the guide does not have the answer, it says so and offers a human.
How it works
Python and FastAPI, BM25 search, Claude or Gemini for the answers. The same assistant works on the web and on Telegram. A limit per visitor and a daily limit keep the AI costs under control.
Result
A working demo with 15 automated tests that all pass. For a shop, the simple daily questions get an answer at any hour, and the hard ones still reach a person. This is a demo project, not a client project.
