SamTerces/AI-first-Builder ? reverse-engineered prompt

Build me a web app that lets someone type a simple idea and turn it into a polished React website in seconds.

I want a clean modern interface where a user can enter a prompt like a portfolio, SaaS landing page, restaurant site, or dashboard, then see the generated site in a live preview alongside the code. It should feel fast, production ready, and easy for founders to use without knowing how to code.

Use a contemporary design with Tailwind styling, nice gradients, responsive layouts, and reusable components. The experience should guide the user from prompt to preview to export, and it should be easy to customize later if I want to turn this into my own AI builder. If you need to check current docs for anything, go ahead and look them up online.

Also make sure the app is set up like a real product, with a workspace area, prompt input, code view, preview area, and a solid base for saving or extending features later.
