Gemini Notebook vs Notebooks in Gemini: What's the Difference?

Short answer: they're two doors onto the same notebooks. Gemini Notebook is the standalone research app that was called NotebookLM until Google renamed it on July 16, 2026 — it lives at notebook.google.com (the old notebooklm.google.com now redirects there), with the full feature set. Notebooks in Gemini is a section inside the Gemini app for organizing your chats and files. The notebooks themselves sync across both, and a third surface — notebooks in Google Search's AI Mode — is on the way. For research work and studio outputs, the standalone Gemini Notebook is the one you want.

Even Google-watchers got confused the day the rename was announced — Forbes literally ran the headline "NotebookLM Is Now Gemini Notebook. I'm Confused." So here is the untangling, in one table and a few paragraphs.

The three "notebook" surfaces, side by side

What the standalone Gemini Notebook does that the app section doesn't

Google put it plainly when it launched notebooks in the Gemini app: you can "use unique features of each app, like Video Overviews and Infographics in NotebookLM, even if you started a notebook in the Gemini app." The standalone app is where the depth lives:

• The studio — Google names Video Overviews and Infographics as unique to this app, and it's the home of the full set: Audio Overviews (the podcast feature), Mind Maps, Flashcards, Quizzes, Reports, and Slide Decks
• The new "secure cloud computer" — code execution for data analysis, rolling out with the rename (what's new in the rename)
• The extension ecosystem — because it's a full web app, extensions can add what Google hasn't built yet: source folders, saved prompts with slash commands, cross-notebook search, bulk import, and audio downloads

The Gemini app's Notebooks section has its own trick, though: it can pull your Gemini chats in as sources, which the standalone app can't do. It's the chat-first door — a place to keep your chats and files organized while you talk to Gemini.

How the sync works

The notebooks are the same on both sides. Google's wording when the feature launched in April 2026: "any source you add in one place automatically appears in the other." The July 2026 rename announcement calls it "full cross-app syncing." Create a notebook in the Gemini app, and it's waiting in Gemini Notebook; add sources in Gemini Notebook, and the Gemini app sees them. One notebook store, two doors — a full-featured door and a chat-first one.

One thing that does not change between the doors: how many sources a notebook can hold. That follows your Google AI plan. When notebooks reached free Gemini users in April 2026, 9to5Google reported the limits as 50 sources per notebook on the free tier, 100 on AI Plus, 300 on Pro, and 600 on Ultra.

The third door, AI Mode in Search, was announced with the rename but hasn't arrived yet. Google says it will "bring notebooks directly into AI Mode in Search" soon.

Which one should you use?

• Students and researchers: the standalone Gemini Notebook. Studio outputs and the deepest feature set live there. If your notebook list is getting unwieldy, that's the gap NotebookLM Tools fills with tags, folders, and cross-notebook search.
• Chat-first work: Notebooks in the Gemini app — especially if you want your Gemini conversations themselves saved as sources. Anything you collect there is waiting in Gemini Notebook when the project grows.
• Content creators (podcast-style audio, video summaries): standalone. Video Overviews are among the features Google calls unique to it, and you can download your Audio and Video Overviews for offline use.

Frequently Asked Questions

Are Gemini Notebook and Notebooks in Gemini the same thing?

Not quite — but they hold the same notebooks. Gemini Notebook is the standalone research app formerly called NotebookLM, at notebook.google.com — until late July 2026 it lived at notebooklm.google.com, which now redirects there automatically. Notebooks in Gemini is a section inside the Gemini app that gives you a space to organize your chats and files. The notebooks sync across both. What differs is what each app can do with them: Google points to Video Overviews and Infographics as features unique to Gemini Notebook.

Do notebooks sync between the Gemini app and Gemini Notebook?

Yes, and they have since April 2026 — before the rename. Google's wording is that "any source you add in one place automatically appears in the other," and the July 2026 rename announcement describes "full cross-app syncing" between the Gemini app and the standalone Gemini Notebook.

Which should I use: Gemini Notebook or the Gemini app?

Since they share the same notebooks, it comes down to what you're doing. Use the standalone Gemini Notebook for research work and for studio outputs — Google names Video Overviews and Infographics as unique to that app. Use Notebooks in the Gemini app when you're working chat-first; it can also turn your Gemini chats into sources.

Was Gemini Notebook previously called NotebookLM?

Yes. Google renamed NotebookLM to Gemini Notebook on July 16, 2026. Same product, new name — here's everything that changed. The rename itself did not change the address; that changed separately in late July 2026, when the app moved to notebook.google.com and the old notebooklm.google.com began redirecting there automatically. The Notebooks section in the Gemini app is a separate, earlier feature that launched in April 2026.

How many sources can a notebook hold?

That depends on your Google AI plan, not on which app you open the notebook in. As reported when notebooks reached free Gemini users in April 2026, the free tier allows up to 50 sources per notebook, AI Plus 100, Pro 300, and Ultra 600.
