Today we're announcing two key updates to NotebookLM: Video Overviews are now available in 80 languages globally, and we're significantly upgrading all Audio Overviews to be more comprehensive and in-depth. Non-English Audio Overviews will now mirror the rich, detailed experience of the English version, providing a more thorough discussion of your sources in all of the supported languages.

Overviews in NotebookLM are summaries of your notebook’s contents, and a great way to more deeply understand them. They help you quickly grasp the key concepts from your sources, so you can spend less time sifting through information and more time learning and creating.

Understand your sources in more languages with Video Overviews

Last month, we introduced Video Overviews in NotebookLM, a powerful way to get a video presentation of a notebook's content. Now, this feature is rolling out to more than 80 new languages.

Whether you're a student reviewing hours of lecture footage to prepare for a final exam, a researcher sifting through a dense academic presentation for key findings, or a curious mind trying to learn a new skill from a complex DIY tutorial, Video Overviews provides a concise, easy-to-understand video in your preferred language.

Listen to longer, more engaging Audio Overviews

Starting today, Audio Overviews in over 80 languages move from short-form to full-length, delivering the same depth, structure, and nuance as our English Audio Overviews. You’ll hear complete, connected discussions that synthesize ideas across your sources, not just quick highlights, so your language choice no longer limits the quality of insight.

And for those moments when you're in a hurry, you can still generate a shorter overview to get the highlights. These updates are available to all users starting today, and rolling out globally over the coming week.
