NotebookLM (Google NotebookLM) is a research and note-taking online tool developed by Google Labs that uses artificial Intelligence (AI), specifically Google Gemini, to assist users in interacting with their documents.

In today’s world information moves fast and across many languages. Staying on top of research, lectures or even your own notes can feel overwhelming. Google’s NotebookLM has been quietly changing that by offering Overviews of your notebooks. These Overviews pull together the important parts so you spend less time searching and more time learning. Now the experience is getting even better with a new update that takes it global.

NotebookLM has introduced Video Overviews in more than 80 languages. Imagine opening your notebook and instead of scrolling through pages of content you watch a short video that highlights the key points. The words and visuals come to you in your own language whether you are studying in English, preparing research in Arabic or revising notes in Turkish. It makes learning feel smoother and much more inclusive.

This change is not only for students. A researcher diving into a dense academic presentation can now receive a clear and engaging summary in the language that makes them most comfortable. A professional catching up on a detailed industry report can now grasp the essentials without spending hours decoding every line. Even someone learning a new skill through a DIY tutorial can benefit because the concepts are explained concisely and in a format that is easy to watch and understand.

Alongside the expansion of Video Overviews, Google is also upgrading Audio Overviews. These have been available in many languages but until now the experience varied. Non-English versions were often shorter or less detailed which limited their usefulness. With the new update every Audio Overview in all supported languages will have the same depth as the English ones. That means you can listen to a connected discussion that pulls ideas together across your sources instead of only hearing quick highlights. It turns a simple audio clip into a more thoughtful conversation with your material.

There is also flexibility built in. Sometimes you need the full picture and want to hear everything the system can offer. At other times you might be in a rush and only want the essentials. NotebookLM lets you choose. You can generate a shorter highlight overview when time is tight or a longer version when you are ready to explore.
