AI Menu Chat & PDF

I need an end-to-end solution that lets diners interact with my menu through an AI chat interface and, on demand, download a polished PDF report of the same menu.

Here is what I have in mind:

• AI chat feature – The user types a question about any item on the menu and instantly receives a concise, friendly answer. Think of it as a waiter who never sleeps. You are free to use OpenAI, LangChain, or another framework as long as latency stays low and answers remain accurate.

• One-click PDF report – From the same interface, the user should be able to export the full menu to a neatly formatted PDF. All menu sections, names, prices, and descriptions must carry over exactly as stored in the database or file you connect to.

I will provide the raw menu data (CSV, JSON, or direct DB access) plus any brand assets you need. You handle the model prompts, backend logic, and front-end hook so the two functions work smoothly together.

Acceptance criteria:
1. Chat answers each menu question correctly in under 2 seconds.
2. Generated PDF matches the latest menu data and brand styling.
3. Code is clean, documented, and ready to deploy on my existing web host (Node or Python welcome).

Send a brief outline of your approach, preferred stack, and a timeline, and we can get started right away.
