Google NotebookLM Expands Video and Audio Overviews to 80 Languages, Enhancing Global AI-Powered Research Tools

Google NotebookLM goes global with multilingual AI video summaries of your notes

NotebookLM creates its summaries from actual uploaded documents Google's NotebookLM first debuted its AI-powered research tool with Audio Overviews capable of making AI-produced 'podcasts' with digital hosts. The logical extension into Video Overviews followed, with a synthetic voice accompanied by a series of slides that include text and illustrations. However, that capability was only available in English until now. NotebookLM Video Overviews are now available in more than 80 languages. For most people, that translates to translatable versions of video walkthroughs based on your uploaded notes and linked source materials. The AI professor is already there and is now a multilingual expert as they present your own content in everything from Tamil to Polish and beyond. These aren't AI summaries scraped from the web or hallucinated based on a vague prompt. NotebookLM is grounded in the actual material you upload. Everything the AI says, in video or audio, is pulled directly from your documents, not from generic training data. Of course, the video in this context isn't a cinematic masterpiece. The slides are not fully animated explainers. This isn't TikTok for term papers; it's more like PowerPoint for people who don't want to make PowerPoints. The goal is clarity, not spectacle. That's not the only global upgrade to NotebookLM, though. While Audio Overviews had been available in many languages recently, they were limited to brief highlights. Now, everyone gets the complete audio AI experience as an alternative to the video option. For those who might want to read a white paper while driving or cooking, this is enormously practical. It won't win a Grammy, but it might just help you understand a textbook or complex report. Professionals working internationally could use it to summarize a week's worth of meeting transcripts as shareable videos or audio recaps from Catalan to Portuguese. No need to rely on a colleague's English comprehension. If you want to see how AI can digest and explain your collection of academic papers, blog posts, and YouTube videos, you can produce a narrated video by uploading your sources as usual, then clicking on the Video Overview button. Shortly, a video of approximately seven minutes will be ready for you to share, download, or use as you wish. That's not to say this solves everything. The AI can still struggle with nuance, for instance. But the reliability of the presentations is valuable on its own. Now, they just look good too.

You Can Now Watch NotebookLM's Video Overviews in All These Languages

The slides are accompanied by an AI audio summary of the topic Google's NotebookLM introduced Video Overviews last month, which can generate narrative-based visual slides based on the selected sources. On Monday, the Mountain View-based tech giant announced that the feature is now available in 80 languages globally. The expansion will now allow users to select sources that are not in the English language and then generate an AI-powered visual summary of the topic. Alongside, the company also announced that it is upgrading Audio Overviews so that it can handle more complex topics. NotebookLM's Video Overviews Now Accessible to Global Users In a blog post, the tech giant announced that Video Overviews will support a total of 80 languages, the same number which is currently supported by the Audio Overviews. With this, the artificial intelligence (AI) tool now supports international languages such as Arabic, Chinese (Traditional and Simplified), Dutch, French, German, Hebrew, Indonesian, Japanese, Korean, Malay, Portuguese, Russian, Spanish, and Vietnamese. Additionally, it is also available in multiple regional Indian languages such as Bengali, Gujarati, Hindi, Kannada, Malayalam, Marathi, Oriya, Tamil, and Telugu. Notably, Google describes Video Overviews as an AI-powered tool that uses slides containing images, diagrams, quotes, and numbers to simplify complex information into an easy-to-understand and engaging format. At the time of launch, Gadgets 360 staff members tested the feature and found that Video Overviews does a decent job of capturing the key takeaways from the given source and presents them with static slides. The slides are narrated by an AI-generated female voice. Unlike Audio Overviews, the feature only offers a single voice-led narration. Google says the feature is useful for students reviewing lectures for a test, researchers sifting through long documents for key insights, or a hobbyist trying to learn a new skill. Alongside, the tech giant is also upgrading Audio Overviews and making them more comprehensive. This will mainly impact the non-English language Overviews, which were only available in short form so far. Google is now allowing users to select sources in any of the 80 supported languages to generate full-length audio discussions that feature the "same depth, structure, and nuance as our English Audio Overviews." Both features are available to all NotebookLM users globally.
