Google expands NotebookLM video overviews to 80 languages: What's new

Google now offers support for 80 languages in NotebookLM's video overviews and richer Audio overviews, making study materials and research summaries more accessible to learners worldwide

Google has expanded accessibility on its AI-powered note-taking platform, NotebookLM, with the rollout of video overviews in 80 languages, including French, German, Spanish, and Japanese. Alongside, audio overviews in non-English languages have been upgraded to match the richness and detail of their English counterparts, offering fuller discussions across all supported sources.

 

Overviews in NotebookLM serve as smart summaries of notebook content, helping users grasp key concepts without sifting through dense material. They are designed to support students, researchers, and professionals by providing quick insights and context.

Video overviews in multiple languages

Introduced last month, video overviews transform notebook sources into AI-narrated slides, combining images, diagrams, quotes, and numbers from documents into concise video explainers. With the latest expansion, users can now generate these presentations in over 80 languages.

 

The feature caters to a wide audience, from students preparing for exams to professionals analysing research papers. By offering visual and spoken explanations in local languages, NotebookLM aims to make complex material more approachable and engaging.

Comprehensive audio overviews

Non-English audio overviews have also been upgraded to deliver the same depth as English ones, said Google. While earlier versions offered only shorter summaries, the new update provides full-length discussions that synthesise ideas across multiple sources for deeper insights.

 

For users who prefer brevity, shorter summary options remain available, giving flexibility between in-depth exploration and quick overviews.

Global rollout

The updates – video overviews in 80+ languages and richer audio overviews – are rolling out globally starting today and will reach all users within a week.
