mendableai/open-lovable ? reverse-engineered prompt

Build me a web app where I can paste a website or describe an idea, then chat with AI to recreate it as a modern React app. I want the experience to feel fast and simple, like a clean landing page with a chat panel, a place to enter the target site, and a live preview of the app being generated. The app should support making edits through chat, so I can ask for changes like different colors, layout tweaks, text updates, or new sections, and see the result update quickly.

Please make it feel polished and production ready, with a nice UI, responsive design, and a smooth flow from starting a project to seeing the final app. If you need to check current docs or best practices for any APIs or services, look them up online.
