NotebookLM is now Gemini Notebook — here's what actually changed

Google announced on July 16 that NotebookLM is now called Gemini Notebook. The name has changed, the logo is getting a blue/purple Gemini gradient refresh, and Google is using the moment to preview two things coming soon: integration with Google Search’s AI Mode, and the Gemini 3.5 + Antigravity upgrade rolling out to AI Pro subscribers.

That’s the short version. Here’s what it actually means if you use the product.

Same tool, cleaner brand story

If you have existing notebooks, nothing breaks. Shared links still work, your sources are still there, and the interface is the same product you already know. Google confirmed automatic redirects will handle any legacy URLs, and the updated name and logo will simply appear across different interfaces over the next several weeks.

The rebrand follows a well-worn Google playbook. Bard became Gemini. Duet AI became Gemini for Workspace. Now NotebookLM, which started life at Google I/O 2023 as “Project Tailwind,” completes the same journey. Folding everything under Gemini makes the product line easier to understand, and frankly “Gemini Notebook” is a more intuitive name than one that has “language model” buried in it.

Google also shared a usage milestone alongside the rebrand: over 30 million people and 600,000+ organisations are now actively using the product. That’s a meaningful number for a tool that, three years ago, was a research experiment.

The feature that matters more than the name

The more substantive news is the Gemini 3.5 + Antigravity upgrade coming to AI Pro subscribers. This isn’t new for everyone — it’s already live for AI Ultra subscribers and Workspace business accounts. The July 16 announcement confirmed it will reach AI Pro users on the web over the coming weeks.

So what does it actually do? Each notebook now gets a secure cloud computer that can write and execute code natively. The practical upshot is that Gemini Notebook moves from being a tool that reads and summarises your sources to one that can run analysis directly on them. Upload a spreadsheet or dataset and it can compute, not just describe.

Google says the upgrade includes access to more than 100 curated software skills, and in its own evaluations the system achieved a win rate above 65% across its top five core evaluation dimensions, with large document analysis hitting a 69.9% win rate. Take internal benchmarks with appropriate scepticism, but the direction of travel is clear: this is meant to handle serious research workloads, not just generate summaries.

Antigravity, for context, is Google’s Gemini 3-Pro-powered development environment. It was built to handle autonomous coding tasks across an editor, terminal, and browser. Bringing that infrastructure into Notebook means the code execution happening in your research environment is backed by something substantial, not bolted on.

Coming soon: your notebooks inside Google Search

Google also previewed integration with Search’s AI Mode. The specifics are limited for now, but the direction is significant: your notebooks will be usable as context when you run AI-assisted searches. That means the research you’ve already compiled, your PDFs, websites, YouTube transcripts, Google Docs, can inform what Search surfaces for you, rather than starting from scratch every time.

Notebooks are already accessible inside the Gemini app for chat and work organisation. Search is the next step in making Gemini Notebook less of a standalone destination and more of a layer that works across Google’s products.

What this means depending on how you use it

If you’re on the free tier: The rebrand is cosmetic. You still get up to 50 sources per notebook and the core summarisation and audio overview features. Nothing is being taken away.

If you’re an AI Pro subscriber: The Gemini 3.5 + Antigravity upgrade is coming to you on the web within the next few weeks. That means code execution and deeper data analysis will be available without upgrading to Ultra. Pro subscribers get up to 300 sources per notebook.

If you’re on AI Ultra: You already have this. The July announcement is largely confirmation that the rollout is widening.

If you use Gemini Notebook for work or research at scale: The Search AI Mode integration is the one to watch. Being able to use curated, source-grounded notebooks as context inside Search could meaningfully change how research workflows connect from discovery through to synthesis.

If you’re in Google Workspace: The rollout timeline may extend beyond 15 days for full feature visibility. The Workspace Updates blog has the specifics for admins.

The bigger picture

Google has been consistent about one thing over the past few years: anything that proves itself gets absorbed into Gemini. NotebookLM proved itself. Thirty million users and a growing enterprise base is not a product you leave with an awkward name.

The more interesting question is what Search integration eventually looks like in practice. Right now, AI Mode in Search is its own context window. Notebooks are their own context window. Connecting them could make both significantly more useful, particularly for anyone who does repeated research in a specific domain. The details will matter, but the intent is clearly to make your saved research portable across Google’s AI surface area rather than siloed in a single app.

For now: your notebooks are safe, your links work, and if you’re on AI Pro, more capable analysis is on its way shortly.
