Gemini Notebooks Officially Launch on Android & iOS

Gemini Notebooks Officially Launch on Android & iOS

We’ve all had that lightbulb moment while standing in line for coffee or sitting on a train an idea that needs a place to live, or a research thread that needs organizing. Until now, the deep, source-heavy research of Gemini Notebooks was mostly a desktop experience.

Google officially brought that power to your pocket. Gemini Notebooks are now rolling out to both Android and iOS, turning your smartphone from a simple chat interface into a mobile command center for your most complex projects.

A Story of Research on the Go

Imagine you’re a researcher or a student. You’ve spent weeks building a massive knowledge base in NotebookLM on your laptop uploading PDFs, links, and notes for a big project. Previously, if you wanted to check a fact while away from your desk, you’d have to dig through your files manually.

Now, you just open the Gemini app on your phone. Tucked into the side panel is your "Notebooks" section. All your desktop research is synced and ready. You can ask, "In that 50-page report I uploaded yesterday, what was the specific finding on renewable energy costs?" and get an answer instantly while walking to your next meeting. It’s no longer just a "chat" with an AI; it’s a conversation with your own curated library.

What’s New for Mobile Users?

1. Seamless Sync: Everything you do in the Gemini app's notebooks section syncs directly with NotebookLM, keeping your research consistent across every device you own.
2. Organized Intelligence: Use notebooks as "smart folders." You can group related conversations and files into a single space, making it easy to manage separate projects like "Home Renovation," "Q3 Marketing Strategy," or "Biology Finals."
3. Tiered Source Limits: Depending on your Google AI plan, you can pack your notebooks with a massive amount of data:
   • Free Users: Up to 50 sources per notebook.
   • AI Plus/Pro: 100 to 300 sources.
   • Ultra Subscribers: A massive 600 sources per notebook.
4. Modern Mobile Design: iPhone users are getting an extra visual treat with the update to Liquid Glass—a new design language for iOS 26 that features slicker menus and a more modern, transparent keyboard interface.

Why It’s a Game-Changer

The move to mobile signals that Google doesn't view AI as just a website you visit, but as a persistent layer of your digital life. By putting "Notebooks" on Android and iOS, they are acknowledging that the most important work often happens in the "in-between" moments.

Whether you’re a professional synthesizing years of client data or a hobbyist organizing a deep-dive into a new topic, you now have a high-context, high-fidelity research tool that goes everywhere you do. The rollout is live now in the U.S., with a European expansion "coming soon."

We used to carry notebooks to write things down so we wouldn't forget them. Now, we carry Gemini Notebooks so the AI can remember everything for us. By bringing this deep research capability to mobile, Google is ensuring that your best ideas always have a home no matter where you are. What's the first project you're taking mobile?
