I built you a starter AI chat app (React + Tailwind). It runs locally in the browser, with a simple chat interface and a dummy AI reply.

Next step options for you:

Hook it up to a real LLM API (like OpenAI, Anthropic, or a local model server).

Add document upload + Q&A.

Deploy as a web app (Vercel/Netlify) or mobile app (React Native).

Want me to wire this starter app to a real backend so it becomes a functioning AI assistant?
