Understand anything with a personalized AI research assistant
By Hafiz Rahman
Editor, tools and utilities
Gemini Notebook is an AI assistant organised around notebooks. Each notebook holds a set of sources, and the assistant works from those sources rather than from general chat. The developer's listing aims it at students, researchers, creators and professionals.
The listing presents it as a way to make long or dense material easier to work through, such as a stack of reports or a set of lectures.
The build we hold is Gemini Notebook 1.63.1.1002728510 (APKS split bundle) for Android 10 and up.

You can upload long or complex PDFs, websites, YouTube videos and plain text into a notebook. Each notebook can hold several of these at once, so related material sits together.
Once the sources are loaded, the app summarises them and makes connections between them, according to the listing. Those summaries and connections are built from the material you added.
You can ask questions at any point, as they occur to you, instead of preparing them in advance. The questions are put to the sources in the notebook.
Answers cite the sources they draw on inline, so each point can be traced back to the document, web page or video it came from.
Audio Overviews are podcast-style audio versions of a notebook's material. The listing says they keep playing with background playback, so you can listen while using other apps.
The listing also says offline support is available for these overviews, which means they can be played without a connection once they are on the device.
