What Gemini Notebook is
Gemini Notebook is a free Google tool that answers your questions using only the documents you upload. You drop in your PDFs, spreadsheets, contracts, manuals, transcripts — then ask in plain language: "what's the termination notice in this contract?", "summarize the 40 pages of this report", "what did customers complain about most in these conversations?". It answers citing exactly where it got each piece of information.
Until July 16, 2026 it was called NotebookLM. Google renamed it to Gemini Notebook, but it's the same product — you don't need to recreate anything.
The new feature that came with it: a "cloud computer"
The rename came with a new, useful capability: every notebook now has a secure cloud computer that writes and runs code on its own. In practice, that means it went from just reading your documents to calculating on them — cross-referencing numbers in a spreadsheet, finding patterns, producing a data analysis from your own sources.
That code feature is rolling out in stages: it started with the higher paid plans (Google AI Ultra and Workspace customers) and reaches "in the coming weeks" all Pro users on the web. Reading and answering from documents — the core function — is already free.
Why it's different from regular ChatGPT
Here's the point that matters most for a business owner. ChatGPT answers from its "general knowledge," and sometimes makes things up with confidence. Gemini Notebook does the opposite: it answers only with what's in your documents, and shows the source citation.
That changes how much you can trust the answer. When it says "the notice is 30 days," you click the citation and see the exact sentence in the contract it came from. Less invention, more traceability — which is exactly what generic AI lacks when the subject is a serious document.
What you can do in a small business
- Find the needle in the haystack. "Which of my 12 contracts has an exclusivity clause?" — instead of rereading them all.
- Summarize what no one has time to read. Reports, e-books, meeting transcripts turn into a half-page summary.
- Turn a manual into a FAQ. Upload your product manual and ask for the 20 most likely customer questions, already answered.
- Analyze your own spreadsheet. With the new code feature: "which month sold the most?", "which product has the highest margin?" — and it calculates.
- Training material. Upload your procedures and generate an onboarding guide for a new employee.
What's free and what's paid
The core function — uploading documents and asking questions with citations — is available for free. The cloud computer that runs code (the heavier data analysis) is the feature arriving via paid plans, starting with the highest and moving down to Pro. For most uses in a small business, the free version already handles a lot.
The caution no one mentions: your data
Let's be candid. For Gemini Notebook to answer, you have to upload your documents to Google — and that often includes customer data, figures, contracts. Before dropping everything in, two precautions:
- Read how Google handles that data on the plan you use (the rules differ between the free account and paid Workspace accounts, which usually have stronger protections).
- Don't upload sensitive third-party data — customer personal information, health data, confidential documents — without a legal basis (GDPR/LGPD). To test what the tool does, start with your own documents, not your customer database.
The tool is excellent; the caution is about what you put inside it.
Frequently asked questions
Is Gemini Notebook the same as NotebookLM?
Yes. It's the same product, only the name changed on July 16, 2026. Your notebooks and sources stay where they were.
Does it make up answers like ChatGPT sometimes does?
Much less, because it answers only from the documents you uploaded and cites the source of each statement. Even so, check the citations for important decisions.
Do I have to pay to use it?
Not for the core function (reading documents and answering with citations), which is free. The new code-execution feature for data analysis is arriving via paid plans.
Is it safe to upload contracts and my business data?
It depends on what you upload and the plan you use. Read Google's data-handling rules and avoid uploading third-party personal data without a legal basis (GDPR/LGPD). Start by testing with your own documents.

Perguntas frequentes
Is Gemini Notebook the same as NotebookLM?
Yes. It is the same product under a new name since 16 July 2026. Notebooks, sources and history all stayed where they were.
Does it make things up the way ChatGPT sometimes does?
Far less, because it answers only with what is in your documents and shows the passage each fact came from. Even so, it is worth opening the citation and checking it before using the information for anything important.
Do I have to pay to use it?
The tool has a free tier that covers most uses. Paid plans raise the limits and unlock new features earlier.
Is it safe to upload contracts and business data?
It depends on what you upload and which plan you use. Read Google's data handling rules and avoid uploading third-party personal data without a legal basis. Start by testing with your own documents.
What is the Gemini notebook?
It is Google's tool that answers questions using only the files you upload, citing the source. It is not the Gemini chat and it is not a note-taking app: it is a space where you gather documents and talk to them. Each notebook is isolated from the others.
What happened to NotebookLM?
It was renamed on 16 July 2026, and that is all. Notebooks, sources and histories remain at the same address and in the same account. There is nothing to migrate, recreate or export.
Does it work in languages other than English?
It does, both for reading documents and for answering in the same language. An English document with a question in another language also works, and it will even translate the quoted passage.
How many documents can I upload?
The limit on sources per notebook and the size of each file vary by plan and change often, so checking inside the tool is safer than trusting any published number. In practice the limit is rarely the problem: notebooks with too many sources and mixed topics degrade the answers long before you hit the ceiling.
Can I share a notebook with my team?
Yes, the same way you share a Google file: by account, with view or edit permission. That is what turns the tool from personal use into a team knowledge base, and it is the step most companies never take.
Does it work on a phone?
It works in the phone browser and is good for looking things up. For building the notebook and organising sources, a computer is still more practical.
What is the difference between Gemini Notebook and ChatGPT?
ChatGPT answers from what it learned about the whole world, which is why it sometimes fills gaps with plausible invention. Gemini Notebook answers only from what is in your files and shows the passage it came from. One is for thinking and creating; the other for looking things up with traceability. A serious company usually needs both, at different moments.
