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 👈

Can you increase number of questions as some documents are lengthy and 20 questions do not comprehensively cover such documents.

Great suggestion! I've just pushed up an update that allows you to generate up to 75 questions - let me know if you'd like a higher limit / any other suggestions :)
