Gemini Notebook - What's New, How to Use It, and Who Can Access It (2026)
Google spent September shipping changes to one of its quieter AI products. You may have opened the tool this month and found a different name. You may also have found a new home for it inside another app, with a book store attached.
You are not imagining any of it. Here is what changed, what it means for your work, and who gets access.
The name changed, and the old address still knows
Start with the part that confuses everyone. The product most people still call NotebookLM now answers to a different name.
Visit the old address and the browser lands on notebook.google.com. Google's own support site tells the same story. The help center path that used to read support.google.com/notebooklm now resolves to support.google.com/gemininotebook. The page that loads is headed "Gemini Notebook Help."
The tool underneath did not get replaced. You still add sources, and it still answers from those sources rather than from the open web. What moved is the branding and, this month, the surface area.
We covered the naming change in our roundup of NotebookLM alternatives, which still uses the older name because that is what people search for. This piece is about the September releases that came after.
What shipped in September 2026
Three announcements landed within four days of each other. Each is small on its own. Together they change where the product sits.
| Release | Date announced | What it does | Rollout |
|---|---|---|---|
| Notebooks in Gemini | September 17 | Notebooks become a dedicated space inside the Gemini app | Gradual, started September 14 |
| Expert Intelligence | September 17 | Published books can be added as sources | Available now |
| Back-to-school tools | September 18 | Learning features for students and educators | Staged |
The first is the structural change. The other two are content and audience plays built on top of it.
Notebooks inside the Gemini app
Google announced notebooks in Gemini back in April, as a focused space for individual users. This month it opened to students, educators, and organizations.
The mechanic is simple. Open the left side panel in the Gemini app and click "New notebook." Then start adding sources.
Each notebook holds one topic. Conversations about that topic stay together instead of scattering across chat history. Anyone who has lost a thread in a long chat log will recognize the problem being solved.
What makes this more than a folder is the handoff between two products. Google's announcement puts it plainly. The update "combines two of Google's most powerful AI tools, the Gemini app and Gemini Notebook."
Their worked example follows a student across two days. On day one, class notes go into a notebook and become a Cinematic Video Overview. On day two, the same notebook opens in the Gemini app, and the same material becomes a study guide.
For professionals, the announcement describes a different input. You upload "product information, project details, research reports, and strategy notes for a specific topic." What comes back is synthesized insight and drafted deliverables.
One limit to plan around: you can add up to 10 sources to a notebook in Gemini.
Expert Intelligence and the book problem
The second release is more unusual. Google describes Expert Intelligence as "a cross Google initiative." Its stated purpose is helping users engage with trusted sources through Google AI products, starting here.
In practice it means published books become sources. Google says the program features "more than 100,000 books from major publishers." Buy an eligible ebook from Google Play Books, add it to a notebook, and you can ask questions answered from its text.
Two details matter before you plan around it.
First, eligibility is per book. Google's guidance is to check the book's detail page on Play Books. If it qualifies, Gemini Notebook appears under the "Tools" badge.
Second, sharing does not transfer the book. Google states the rule directly. To interact with an ebook in a shared notebook, "recipients must also have purchased an eligible Play Book ebook."
That second rule is the one that will surprise teams. A shared notebook is not a shared library. If four people need to work from the same title, four people need the title.
There is an admin dimension too. End users need to sit in an organizational unit with three services switched on. Those are Gemini Notebook, Google Play, and Google Books. Schools on the Education Plus or Teaching and Learning tiers can buy books centrally and allocate them, without handing out broad Play access.
The back-to-school release
The September 18 announcement rounds out the education push. It adds learning tools aimed at students and teachers, and follows the same pattern as the other two releases.
Google's framing across all three is consistent. Educators upload "curriculum standards, assignment rubrics, and lesson templates," then get aligned coursework back. Students upload course material and get quizzes and study guides.
The output formats are worth noting, because they are not all text. Google lists Infographics, Audio Overviews, and Quizzes among the artifacts a notebook can generate from its sources.
Who can access Gemini Notebook
This is where most access problems get resolved. Google's FAQ lists the checks in order.
- Age verification. You need to verify your age in your Google Account before access opens.
- Region. The Gemini app is available in 180+ regions, and your country needs to be on that list.
- Account type. Work and school accounts depend on admin settings. The FAQ is blunt about the fix: "To turn on the Gemini Notebook app, work with your workspace admin."
- Notebooks in Gemini specifically. Access is on by default. Users still need to sit in a group or organizational unit with both Gemini Notebook and Gemini set to On.
For organizations, Google routes higher limits and enterprise-grade data protection through three products. Those are Google Workspace, Google Workspace for Education, and Google Cloud.
On price, the consumer tiers sit on Google's AI plans page. No pricing page is owned by the notebook product itself. Three plans are listed there. Google AI Plus is $4.99 per month, Google AI Pro is $19.99 per month, and Google AI Ultra starts at $99.99 per month, with a higher-access variant at $199.99.
Sharing, privacy, and what the icons mean
Sharing behavior is easy to get wrong, because the signal is a small icon rather than a sentence.
A lock icon means the notebook is private and shared with nobody. It changes to a shared icon once you share with named users. It becomes a globe icon when the notebook is public.
Check that icon before you paste anything sensitive into a notebook you inherited. The difference between the second and third state is the difference between a team document and a published one.
On data handling, Google's FAQ is a single line: "Your data will never be shared by Gemini Notebook." The company points to a separate page for how that protection works in practice.
Three source-handling rules round out the picture, and they matter for anyone building a repeatable workflow. Notes are used in a prompt only when you specifically select them. Sources are always used, either the full set or the subset you pick. Conversation history is used to generate responses.
That last rule is the one to remember in long sessions. Earlier turns in the conversation shape later answers, so a notebook that has drifted off topic will keep drifting until you start a fresh one.
Limits worth knowing before you upload
Google publishes hard numbers, which is more than most vendors do. These come from the official FAQ.
| Limit | Value |
|---|---|
| Words per source | 500,000 |
| File size per local upload | 200 MB |
| Page limit | None stated |
| Sources per notebook in Gemini | 10 |
Several behaviors are documented alongside those numbers. Copy-protected PDFs will not import. Deleted notes cannot be recovered. Duplicating a notebook is listed as not yet supported.
One retrieval behavior deserves attention. When a notebook holds many sources, the tool retrieves what it judges most relevant, then builds an answer from that subset. Google's own advice is to ask precisely, because "a specific question helps Gemini Notebook locate the most relevant pieces of information."
Citation behavior shifts with source length as well. Short sources get referenced as a whole rather than by passage. That matters if you plan to quote from them.
How to start, in the order that works
- Verify the account first. Age verification and region come before anything else. Work accounts need the admin switch flipped.
- Create the notebook from the side panel. Name it after the topic, not the task. Topics outlive tasks.
- Add sources in one pass. Ten is the ceiling in Gemini, so pick the ten that carry the argument.
- Ask narrow questions. Broad prompts across many sources return broad answers.
- Check the citations before you quote. Short sources get referenced whole, not by passage.
Where it sits next to the rest of your stack
Gemini Notebook is built around sources you hand it. That is both its strength and its boundary. It reads what you upload and answers from that material, with links back to the passage.
For a reading list, a policy set, or a stack of research papers, that is exactly right. The tool does not wander off into the open web and return something you then have to verify.
The shape of the work changes when the question does. "What do these documents say" is a retrieval problem. "What do these numbers do" is an analysis problem.
Spreadsheets, database tables, and exports need a tool that runs the analysis and shows which row produced which figure. That is a different job from summarizing a reading list. It is the one Powerdrill Bloom was built for, with answers that come back carrying the page, the row, and the figure behind every number.
Plenty of teams run both. The notebook holds the reading. The analysis workspace holds the data. If you are mapping that second half, our roundups of Gemini Deep Research alternatives and Jupyter Notebook alternatives cover the tools that do it.
