Introducing Video Overviews and upgrades to the Studio panel in NotebookLM

What’s changing 

Since introducing Audio Overviews last year, NotebookLM users have created podcast-like, detailed summaries of key topics from their uploaded sources. To build upon this functionality and provide users with a more educational and visual experience, we’re excited to introduce Video Overviews.

Users can now turn documents, slides, charts and more into engaging explainer videos that are narrated by an AI voice. Video Overviews are expertly-crafted visual walkthroughs of the content you provide, pulling in images, diagrams, quotes, and numbers from your source material. Similar to Audio Overviews, you’ll also have the option to customize your Video Overview by specifying topics to focus on, indicating your learning goals, describing the target audience, and much more. At this time, Video Overviews are only available to users over the age of 18. 

We’re also introducing upgrades to the Studio panel where you would create things such as audio overviews and notes in NotebookLM, which includes multiple audio overviews and content sharing. Specifically, users can now:
  • Generate multiple Audio Overviews in a single notebook. This means you can now create versions in different languages from the same source material, or generate a set of Audio Overviews that each focus on different subsections of your sources.
  • Generate shareable links for content like Audio Overviews and Video Overviews, which cannot be shared outside of your domain. 


Additional details

  • Video Overviews are now rolling out to all users in English, with support for more languages coming soon. 
  • Only users with access to your Notebook can view content you share via a shareable link.

Getting started 

  • Admins: There is no admin control for this feature. 
  • End users: Visit the Help Center to learn more about Video Overviews and NotebookLM.

Rollout pace 

  • This has already started to roll out targeting 100% the week of August 4, 2025.

Security Fixes and Rewards

Note: Access to bug details and links may be kept restricted until a majority of users are updated with a fix. We will also retain restrictions if the bug exists in a third party library that other projects similarly depend on, but haven’t yet fixed

This update includes 4 security fixes. Below, we highlight fixes that were contributed by external researchers. Please see the Chrome Security Page for more information.

We would also like to thank all security researchers that worked with us during the development cycle to prevent security bugs from ever reaching the stable channel.

As usual, our ongoing internal security work was responsible for a wide range of fixes:
