How free80/100
Value7/10
How these scores work
Free Score (0–100) follows a fixed rubric: cards up front, auto-billing, hard time cutoffs, withheld core features, and paying with your data or attention all deduct points. 90–100 truly free · 70–89 free forever · 45–69 squeezed · 15–44 trial mechanics · under 15 fake or gone. Value (0–10) is editorial: real-world worth of the free offering measured against its paid equivalent. Full rubric on the methodology page.
Yes — Google's research notebook is free with a Google account: upload sources, ask questions, get cited answers, generate the podcast-style audio summaries. Plus mainly raises caps.
What it’s worth
The closest paid equivalents are $20/month research tools; the free tier does the core job.
What you get free
- Upload your documents and query them with citations
- Audio Overviews — the two-host podcast summaries
- Real source-grounded answers, not open-web guessing
In practice: a genuinely free grounded-research tool — your documents, cited answers, audio summaries.
Drawbacks
- Google account required
- Source and notebook caps
- Experiment-status product risk
Also paywalled
- Higher notebook/source caps and team features (Plus)
Free facts
| Verdict | Free Forever |
| Card required | No |
| Auto-bills | — |
| Account | Google account required |
| Limits | Caps on notebooks and sources per notebook; higher caps in the paid Plus tier |
| The real cost | Nothing at the free tier. |
The catch
Everything routes through your Google account, caps are real for heavy research use, and Google has a history of retiring experiments — don't make it your only archive.
The smart play
- Keep master copies of your sources elsewhere — treat it as a lens, not a library
- Audio Overviews are the standout: feed it a dense PDF before a commute

How is this different from ChatGPT?
It only answers from the sources you give it, with citations — which means far fewer invented facts, and it's actually checkable.
