nimaman/notebooklm ? reverse-engineered prompt

Build me an open source, privacy focused app like Notebook LM where I can keep multiple notebooks for different topics, upload things like PDFs, docs, EPUBs, links, YouTube videos, audio, video, markdown, and pasted text, then ask questions about them and get answers with citations.

I want the app to help me turn source material into useful notes and insights, and also generate a podcast style summary from my content with customizable speakers and voices. It should let me choose which AI model to use, since I may want to switch between different providers, and it should keep good control over what content gets sent to the AI.

Make it feel like a clean research workspace, with search, notes, and a simple notebook view that is easy to use. If you need to look up any current docs online while building it, go ahead.
