airlanggapradana/uploadxam ? reverse-engineered prompt

Build me a web app for FKI UMS students called UploadXam that lets people share and find exam papers from UTS and UAS in a simple, modern way.

I want students to be able to log in with their NIM, browse exam papers by study program, course, and year, and upload PDF files easily. Please make the interface clean, responsive, and comfortable to use on mobile and desktop, with a polished look using modern UI components and a nice tailwind based design. The app should also have an AI assistant that can answer questions about academic info, curriculum, course lists, and how to use the platform, using the documents and knowledge already in the system.

Use a proper backend and database so the files and metadata are stored safely, and make the whole experience feel fast and reliable. If you need to look up current docs online for anything, go ahead and do that.
