A clean, Free-user-friendly AI chat interface with:

responsive desktop/mobile UI
conversation persistence in the browser
new/clear chat
dark mode
quick prompts
text-file context
backend API proxy so the API key is NOT exposed in browser code
configurable model
basic request/context limits

Run locally

Install Node.js 18+.
Open a terminal in this folder.
Run npm install.
Copy .env.example to .env.
Put your API key in .env.
Run npm start.
Open http://localhost:3000.

Production notes

Do not put the API key in app.js or HTML. Add authentication, server-side rate limiting, abuse protection, logging, and a database before public deployment.

The browser stores chat history locally. The backend receives only the recent messages sent with each request.
