Is there a Gemini Notebook app to download?
Yes, on mobile. Gemini Notebook (formerly NotebookLM) has apps for Android on Google Play and for iOS on the App Store. On a computer there is nothing to download: you use it in a web browser at notebook.google.com.
In more detail
On phones and tablets, install the Gemini Notebook app from Google Play or the App Store and sign in with the same Google account you use on the web. Your notebooks sync between devices. The September 2026 study features, including the lecture audio recorder and real-time voice conversations with a notebook (for users 18 and over), are in the mobile apps. On Windows, macOS, ChromeOS and Linux, open notebook.google.com in your browser; old notebooklm.google.com bookmarks redirect there. To log in, use a Google account; on a work or school account, your administrator has to turn Gemini Notebook on. Browser extensions, such as Gemini Notebook Toolkit, are third-party add-ons that work alongside the web version and are not made by Google.
