Use one real document set with proprietary or time-sensitive content. Verify whether answers stay grounded in your sources rather than hallucinating from general knowledge. Check export quality for study guides and audio overviews. Compare against at least one alternative before relying on it for regular research.

Current official summary: NotebookLM is now Gemini Notebook (the official FAQ states the rename took effect in July 2026). The product remains free for individuals with standard usage limits and up to 50 sources per notebook. Gemini Notebook is also included in Google AI Plus (double the standard usage limits, up to 100 sources), Google AI Pro (four times the standard limits, up to 300 sources), and Google AI Ultra (5-20x the Pro limits, up to 600 sources). The plans page does not publish US-dollar prices; the paid tiers are billed through Google One and are available only in listed regions. Organizations, schools, and enterprise access route through Google Workspace or Google Cloud.
Open verification questions
- The Gemini Notebook plans page does not publish US-dollar prices; the Plus, Pro and Ultra tiers are billed through Google One and are region-limited.
- Google's general terms and policies govern use; no product-specific commercial-use or output-ownership clause was found on the Gemini Notebook pages.
- The rename from NotebookLM to Gemini Notebook may not be fully reflected across all Google surfaces.
Official about page checked 2026-09-01. The page states: 'We value your privacy and never use your organization's data to train Gemini Notebook.' When used as an individual, data is not used for training unless the user shares feedback. The product is powered by Gemini's multimodal capabilities. A support page (support.google.com/gemininotebook/answer/16179536) provides additional privacy details. Privacy and Terms are governed by Google's policies at policies.google.com. Re-verified 2026-10-01: Google now publishes a dedicated Gemini Notebook plans page, which the 2026-09-01 check on the about page did not surface. The plans page is entitlement-based and still publishes no dollar amounts; pricing sits with the Google One AI Plus/Pro/Ultra subscriptions. The privacy statement is unchanged: organization data is never used to train Gemini Notebook, and individual data is not used for training unless the user shares feedback.

The AIToolsEssentials rating is an editorial score—not an external benchmark. It summarizes job fit, likely output quality, ease of adoption, and operational cost using published product information, benchmark context where the exact model is identifiable, and the repeatable trial checklist above. Benchmarks never determine the final product rating by themselves. See our editorial methodology, evidence ledger, and benchmark evidence policy.
