The catch
Answers are grounded in what you upload, which is the point — but it will not go and fetch new material for you.
Why it made the list
Grounding to your own documents removes most of the hallucination problem that makes general chatbots risky for study.
How this was checked
The limits above were read directly from Google NotebookLM's own pricing or documentation pages on 2 Aug 2026 — not taken from a roundup article. That distinction matters more than it sounds: 11 tools were rejected from this site specifically because the widely-repeated free-tier numbers did not survive contact with the vendor's own page.
Free tiers change without announcement, and they usually shrink. If you are reading this well after 2 Aug 2026, open the pricing page yourself before committing to anything.
