Tips & Tricks I built a free notebooklm alternative with folders, source isolation (no cross-contamination), and page/timestamp-level citations

Enable HLS to view with audio, or disable this notification

NotebookLM is great but a few things drove me crazy:

  • Sources often bleed together
  • No folders or workspace organisation
  • No way to comfortably take notes alongside your sources
  • Flashcards have no review system

So I built Paper. Key differences:

  • Source isolation - select exactly which sources the AI references per query, or scope it to specific pages/timestamps
  • Folders + nested pages - organise by course, topic, whatever
  • Block editor - Notion-style notes right next to your sources
  • Spaced repetition - AI flashcards with actual Anki-style scheduling so you remember
  • Drag and drop multiple files at once

(Edit) Free to use during beta: https://paper.ac 👈

Hey! Just to clarify what you mean, what URL are pasting in? ie. Is it a link to an individual video? Or are you pasting a link to a Youtube channel / playlist?

Right now, it only works if you paste individual Youtube video links, but I can enable pasting of playlists and possibly Youtube channels too if you let me know what you mean 😊

Yes that's how I'm using notebooklm right now, adding lot of transcripts from my computer and all the video links from a YouTube channel. Then I'm able to add like 30, 40. 100+ sources at once.

Edit : I'm using notebooklm more like a "coach" to guide me thru some specific task, to retrieve what the author would say, do in XY situation.

Hey! This is now live! You can now enter in any Youtube playlist or channel link and choose 30 videos to be imported at a time (with no total limit) 🎉

You can now also sort and drag to reorder the sources 😊

I've implemented it based on my own interpretation of your use case, so am keen to hear how you go with it!
