pranav14-1/StudySphere ? reverse-engineered prompt

Build me a study app called StudySphere that lets people upload PDFs and turn them into an interactive learning workspace. I want an AI teaching assistant that can answer questions from the uploaded material, show where the answer came from, and keep trying again if the first search is not good enough. The app should also support live collaboration, so multiple people can be in the same study space and see updates in real time.

Please include automatic study tools like quizzes, summaries, and study plans based on the documents, and make the answers feel streamed and responsive instead of waiting forever. If a question is not really about the uploaded files, it should be smart enough to look up general info online when needed. Make the UI feel clean and modern, and keep the whole thing focused on helping people learn faster from their own materials.
