unique841426/AI-Code-Review-Platform ? reverse-engineered prompt

Build me a web app where people can sign up, log in, and paste in code or upload a file to get an AI code review.

I want it to feel like a modern coding tool, with a clean dark interface, a good code editor, syntax highlighting, and a dashboard where users can see their past reviews, search through them, filter them, and delete anything they do not need anymore. The app should do some basic static analysis too, so it can catch obvious bugs and code issues even before the AI review.

Please make the review results useful and easy to read, with suggestions for bugs, refactoring, and documentation improvements. Use secure authentication with hashed passwords and JWT based login. If there is no AI key set up, show a simple fallback response instead of breaking. Build it as a full stack app with a React frontend and a Node and Express backend with MongoDB, and make it responsive so it works well on desktop and mobile. If you need to look up current docs online, feel free to do that.
