LatikaMadankar/LexoAI-ChatBot ? reverse-engineered prompt

Build me a simple AI chat app called LexoAI ChatBot with a clean web interface and a backend that can handle the chat logic.

I want users to be able to open the site, type a message, and get a fast, helpful reply in a chat style conversation. Make it feel polished and easy to use, with a modern layout, a message history area, and a clear input box with a send button. Please wire up the frontend and backend so the chat actually works end to end, and keep the code organized so it is easy to run and extend later.

If you need current setup details for any libraries or API usage, look them up online and use the best current approach. Also add sensible error handling and a simple loading state so it does not feel broken while waiting for responses.
