More on this

Both come from Google, and since July 16, 2026 the names overlap: Google renamed NotebookLM to Gemini Notebook. It is the same product with the same notebooks, so you may see either name. Gemini is a different app, the general assistant. Your notebooks now show up in both, and renaming one, adding sources or editing its instructions carries over to the other.

The practical difference is what an answer may draw on. In Gemini Notebook, Google says responses are grounded exclusively in your notebook sources. In Gemini they are grounded in the same sources but can also use web search and other tools. Video Overviews and infographics are Gemini Notebook features, while Gemini can also make Audio Overviews, quizzes and flashcards from chat or Canvas. Gemini's own addition is study notebooks in the web app: a diagnostic quiz, short lessons and progress tracking, with Keep Activity turned on.

On money it is a tie. Both are free with a Google account, and Google AI Plus ($4.99 a month) or AI Pro ($19.99) raises the limits in both. As of October 2026, eligible US college students can get AI Pro free for a year if they redeem by December 31, 2026. Both help you understand material you already have. Gemini also builds quizzes and, for set exams such as the SAT, full-length practice tests. A study-first tool such as StudyPDF is built to turn your own course files into practice exams and a score for every concept.

Questions and answers

Is Gemini the same as NotebookLM?

No, but they are linked. NotebookLM is now called Gemini Notebook, a separate app for working with your own sources. Gemini is Google's general assistant. Since 2026 your notebooks show up in both and stay in sync, but answers in Gemini Notebook come only from your sources, while Gemini can also use web search.

Is NotebookLM free?

Yes. As of October 2026, Gemini Notebook, the new name of NotebookLM, is free with a Google account: 100 notebooks with up to 50 sources each. Usage limits reset every five hours, with a weekly cap. Google AI Plus ($4.99 a month) allows 200 notebooks with 100 sources and twice the limits; AI Pro ($19.99) allows 500 notebooks with 300 sources and four times the limits.

What are the limitations of NotebookLM?

It stays inside the sources you add, so it cannot fill a gap in your notes. Usage limits depend on prompt length, sources and features, and reset every five hours with a weekly cap. A deleted notebook cannot be recovered. Google presents it first as a research tool; for timed practice exams and a score per concept across a course, look at a study-first tool such as StudyPDF.

Which is better for studying, NotebookLM or Gemini?

They do different jobs. Gemini Notebook is better for checking what your lecture says, because answers stay in your sources. Gemini is better when you need another explanation or context from the web. Its study notebooks add a diagnostic quiz and progress tracking. If you must pick one for exam prep on fixed files, start with Gemini Notebook.

Are Gemini and NotebookLM free for students?

Yes, for a year if you are eligible. As of October 2026, eligible US college students aged 18 and up can get Google AI Pro free for a year, with four times the Gemini Notebook limits. Eligible students in 140+ other markets get AI Plus free for a year, with twice the limits. Redeem by December 31, 2026; after that it costs $19.99 or $4.99 a month unless you cancel.
