HyDrSnic/Quiz-Generator ? reverse-engineered prompt

Build me a web app that lets someone upload a document and turn it into a quiz automatically.

It should accept PDF, DOCX, PPTX, and TXT files, then extract the text, generate multiple choice questions from it, and show the quiz in the browser. I want each question to include source citations so the user can see where the answer came from, plus explanations and a review screen for wrong answers.

The app should work without a login, use a simple session based flow, and keep each user’s uploads and quizzes separate. Add a progress indicator while the quiz is being generated, because that may take a bit. Also make the results page show the score, the correct answers, and the source quotes used for each question.

If you need current library details or best practices, look them up online and build it in a clean, modern way with a simple frontend and backend.
