NotebookLM Statistics
How Many People Use NotebookLM in 2026?
Google puts NotebookLM at more than 30 million people and over 600,000 organizations. Josh Woodward, VP of Google Labs, the Gemini app and AI Studio, shared both figures in the July 16, 2026 post that renamed the product.
The post does not say whether the 30 million count is monthly, weekly or cumulative.

What Is NotebookLM Called Now?
It is now called Gemini Notebook. Google kept it as a standalone research product, and notebooks now sync with the Gemini app.
Google’s help center now sends users to notebook.google.com. The company also said it would bring notebooks into AI Mode in Google Search.
Google said on August 11, 2026 that the Gemini app had passed 1 billion monthly users. That count uses a different definition, so the two figures are not like-for-like.

Limits for consumer accounts became compute-based on September 2, 2026. Prompt complexity, chat length, source count and the features used all draw on the quota.
The quota now refreshes every five hours until a user hits a weekly cap. Under the old system, limits reset daily.

Is NotebookLM Still Free?
Yes. The Standard plan costs nothing with a Google account.
Gemini Notebook is also included free in all Google Workspace for Education editions, for users of all ages. That places it inside the wider Google for Education user base.
US college students can claim one year of Google AI Pro at no cost, which Google values at $19.99 a month. Eligible students in 140+ other markets get a free year of Google AI Plus. Both offers must be redeemed by December 31, 2026.
