Google talks up NotebookLM upgrades by making it talk up Google I/O 2025

Google used news from its I/O developer conference this year to show what NotebookLM can do. The AI-powered research and note-taking tool has been around for years, but the company has infused it with more and more features as its AI tech improved. To demonstrate those features, Google created a notebook filled with news from I/O 2025, including a YouTube video of the keynote (complete with a transcript of the whole event), press releases, blog posts and even product demonstrations. You can visit all of those one by one, since the company uploaded them as sources to the notebook, but you can also use the AI tool to digest all the information for you.

You can ask NotebookLM anything you want about the event in the chat box, so that you can quickly find details for whatever it is you want to know. When I asked it what is NotebookLM, for instance, it gave me a response that aligned with what was announced during the event. "According to Google's announcements at I/O," the tool responded, "...NotebookLM becomes an 'expert' by grounding its responses in the provided material and offering creative ways to transform information."

Under the Studio section of its interface, you'll be able to generate audio overviews that can give you a quick or a more comprehensive spoken summary of the information you've uploaded. You can also create a Mind Map, which visually summarizes uploaded sources, showing one main topic branching towards several smaller topics and relevant ideas. Mind Maps are meant to structure information in a way that's easier to understand and remember. Google added a reminder to its announcement, however, that "like all AI, NotebookLM can generate inaccuracies," which is something to keep in mind while using the tool.

Google has released an official app for the tool in time for I/O 2025, which you can now download on Android or iOS. To see the company's I/O 2025 notebook, you'll have to be signed into a Google account.

Google's annual I/O developer conference kicked off on Tuesday, May 20. See everything Google has announced at I/O 2025 so far, including an AI-powered movie creation tool called Flow, real-time translation in Google Meet, virtual clothing try-ons based on uploaded photos, AI enhancements to Project Astra computer vision and more.
