sohan-05-info/project-IntelliPrep-study-assistant ? reverse-engineered prompt

Build me a simple study assistant web app that lets a student upload or keep textbook PDFs and ask questions about them in plain English. It should read the PDFs, split them into useful chunks, search the most relevant parts, and then give clear, conversational answers based on that content so it feels like studying with a helpful tutor instead of hunting through long documents.

I also want it to suggest a few related YouTube videos for the question the student asked, so the app combines text explanations and video help in one place. Make the interface clean and easy to use in Streamlit, with an upload area, a chat style question box, and an answer panel that shows the response and the recommended videos.

If you need to look up current library docs while building it, feel free to do that.
