NirajanBanjade/Kwizzy — reverse-engineered prompt

Build me a clean quiz practice app called Kwizzy. I want people to be able to sign up, log in, and then generate quizzes from any topic they type in. The app should use AI to create good multiple choice questions, let the user answer them one by one, show whether they were right or wrong, and give a final score at the end.

Please also save each user's quiz history so they can come back later and see what topics they practiced, their scores, and when they took each quiz. Keep the interface simple, modern, and easy to use, with a nice flow from login to topic entry to quiz results.

Use a React frontend, a Node backend, and PostgreSQL for storing users and quiz history. Authentication should be secure with JWT. Set it up so I can run everything locally, including the database, and include clear setup instructions. Look up current docs online if you need to.
