Gemini Notebook is Google’s AI-powered research assistant: you upload documents, slides, web pages, or videos, and it answers questions, writes summaries, and builds study aids using only that material — citing the exact passage each answer came from. Google renamed the tool, previously known as NotebookLM, to Gemini Notebook on July 16, 2026, tying it more closely to the wider Gemini brand while keeping it a separate, purpose-built product rather than folding it into the general-purpose chatbot.
What it actually does
Most chatbots answer from everything they were trained on, which is why they sometimes invent facts that sound plausible but aren’t true. Gemini Notebook works differently: it uses retrieval-augmented generation to search only the sources you’ve uploaded — PDFs, Google Docs and Slides, websites, and YouTube videos — and grounds every answer in a citation you can click to check.
Beyond a chat panel, a “Studio” panel turns your sources into other formats: podcast-style Audio Overviews (two AI hosts discussing your material), slide-style Video Overviews, study guides, flashcards, quizzes, mind maps, and infographics. The newest addition is code execution: each notebook can now spin up a sandboxed cloud computer to write and run code against your data — useful for turning a spreadsheet of sources into an actual chart or calculation instead of a text description of one.
From NotebookLM to Gemini Notebook
The tool has changed names twice. It launched in 2023 as an experimental project called Tailwind, was rebranded NotebookLM later that year, and dropped its experimental label in October 2024. On July 16, 2026, Google’s Josh Woodward (VP of Google Labs, the Gemini app, and AI Studio) announced the Gemini Notebook name, alongside code execution and a plan to sync notebooks into the Gemini app and Google Search. Existing notebooks, sources, and sharing settings carried over unchanged — only the name and logo changed. As of the rename, Google reported more than 30 million individual users and 600,000-plus organizations using the product.
How do you use it
You need a personal or work/school Google Account. From there:
- Go to Gemini Notebook and sign in.
- Select “Create new notebook.”
- Upload sources — documents, slides, web links, PDFs, audio files, or YouTube videos. A “Discover sources” option can search the web to suggest documents to add, but the assistant only answers from what’s actually in your notebook.
- Ask questions in the chat panel; each answer links back to the source passage it came from.
- Open the Studio panel to generate an Audio Overview, Video Overview, study guide, or the other output formats.
- If you’re on a paid tier, use the built-in code execution to run calculations or generate charts directly from your sources.
Each notebook is self-contained — Gemini Notebook won’t mix information across two separate notebooks — which makes it a natural fit for one notebook per project, class, or research topic.
What it costs
The core product is free with any Google Account. Paid Google AI subscriptions raise the usage limits and unlock features earlier: as of July 2026, per Google’s pricing page, Google AI Pro runs about $20/month, and Google AI Ultra comes in two tiers, roughly $100/month and $200/month, with the higher tiers getting first access to features like code execution before they reach free and Pro users. Prices vary by country, so check the pricing page for your region’s current numbers.
Why it matters
As AI tools multiply, a growing share of the useful ones aren’t general chatbots but assistants bound to a specific set of documents, with citations attached to every claim. That combination — grounded answers plus a visible source trail — is what makes a tool usable for the kind of work where being wrong has consequences: a student citing sources in an essay, a lawyer checking a filing, an analyst summarizing a stack of reports. Gemini Notebook’s scale (30 million-plus users) suggests that source-grounded, citation-first AI has become a mainstream way people actually work with AI, alongside open-ended chat rather than instead of it.

FAQ
Do I have to pay to use Gemini Notebook?
No. It’s free with a Google Account. Paid Google AI Pro and Ultra plans raise usage limits and give earlier access to new features.
What happened to my old NotebookLM notebooks?
Nothing structural — Google says existing notebooks, sources, and sharing settings carried over unchanged under the new name.
Can Gemini Notebook browse the open internet to answer questions?
No, not by default. It answers only from the sources you’ve added, though a source-discovery feature can search the web to suggest documents you might want to add.
Is Gemini Notebook the same product as the Gemini chatbot app?
No. Gemini is Google’s general-purpose assistant; Gemini Notebook is a separate, source-grounded research tool, though Google is starting to sync notebooks into the Gemini app and Google Search.
