What NotebookLM actually is

  • Grounded chat on your own sources (PDF, docs, URLs, YouTube), so answers come out of your material only
  • Audio Overviews turn your sources into a podcast-style summary
  • The most generous free limits on this list for serious research work

Limits and catches

  • 3 Audio and Video Overviews per day on Free, which runs short quickly for batch work
  • Google publishes these limits through support pages and adjusts them, so treat the numbers as current rather than fixed
  • Renamed in July 2026: Google now calls NotebookLM 'Gemini Notebook'. Same product, same free tier, and sources use both names interchangeably

What does NotebookLM cost?

Yes, permanently free with no time limit and no credit card: up to 100 notebooks, 50 sources per notebook, 50 chat questions per day, 3 Audio Overviews per day, 3 Video Overviews per day, 10 reports per day and 10 Deep Research sessions per month. Each source is capped at 500,000 words or 200 MB on every tier. Reconfirmed on 31 July 2026: you pay to raise limits, never to unlock a feature.

Free AI tools that are actually free (no trial tricks)

I checked 16 AI tools for a real free tier. Nine are actually free, two are trials in disguise. One question exposes the trick every time.
