Abhi-sheKkK/SmartLearn.AI ? reverse-engineered prompt

Build me a web app that turns long YouTube lecture videos into a smart study workspace.

I want to paste in a YouTube link and have the app pull the transcript, find important visual moments from the video, and then generate useful study materials from it. It should make clean notes with equations and diagrams, let me ask follow up questions in a chat, create quiz questions with instant grading, and run a viva style practice mode where the app asks me questions and gives feedback on my answers.

Please make it feel polished and easy to use, with a nice dashboard, a landing page, and a modern glassy look. The app should save sessions so I can come back to them later. If it helps, use AI for the explanations and make the results stream in gradually instead of waiting for everything at once. If you need current docs or examples for anything, look them up online first.
