GraeLefix/GITVERSE ? reverse-engineered prompt

Build me a web app that lets someone paste in code files or a public GitHub repo link, then uses AI to reverse engineer it into a clean, copy ready build prompt for another coding agent.

I want the app to explain the codebase in plain language, show the overall architecture with a simple ASCII style diagram, and generate one detailed reconstruction prompt that includes the important files, dependencies, environment variables, APIs, and any deployment notes. It should also support an incremental mode where I can paste files one at a time and type GITVERSE_DONE when I am finished.

Make it feel polished and easy to use, with a simple home page, a results screen, and a small saved library if that fits naturally. Use current docs online if you need to, and keep the code privacy friendly so pasted code is not stored permanently. I also want it to work with a few different AI providers, with automatic fallback if one is unavailable.
