anshulp2912/scrivener ? reverse-engineered prompt

Build me a simple web app that summarizes YouTube videos. I want to paste in a YouTube link, or upload a video file, or type in some text, and get back a clear summary of the transcript or content in a readable format.

Make the interface clean and easy to use, with a nice Streamlit style page and a result area that shows the summary after processing. If the video has captions, use them to generate the summary. If it’s a local mp4 file, handle that too. Keep the app focused on summarizing video transcripts well, and make it feel polished enough to run locally right away.

Please include everything needed so I can install the dependencies and launch it easily from the command line. If you need to look up current docs online for anything, go ahead.
