Google has released new NotebookLM apps for Android and iOS, giving users access to AI note-taking on the go. The apps bring smart summaries and audio overviews to phones and tablets. Users can add new sources from websites and videos with a tap and listen to AI-generated overviews offline. These mobile apps mirror the desktop experience and come just before Google I/O 2025.
New Mobile NotebookLM Apps
Google made the NotebookLM service available only on desktops since it launched in 2023. On May 19th, Google announced that the Android and iOS versions are live a day ahead of schedule. The launch meets high user demand for a native app experience instead of a web-based interface.
Key Features in the Apps
The mobile apps let users upload PDFs, websites, and YouTube links as new sources with the system’s share feature. The Audio Overview feature creates podcast-style summaries that play in the background or offline. Users can start new notebooks, view existing ones, and review uploaded sources at any time. The app adapts to light or dark mode based on device settings for a seamless look.
How to Use the Mobile App
When viewing a website document or video, tap the share icon, then select NotebookLM to add it as a source. In the app, users see all their notebooks on a home screen with filters for recent shared and downloaded items. Users can then ask the AI to summarize, explain, or answer questions about their sources. Audio Overviews appear as playable items in each notebook for easy listening.
Why This Matters
NotebookLM helps people understand complex information quickly by using AI summaries and insights. The mobile app puts research tools in users’ pockets, letting them learn anywhere and anytime. With offline support, professionals, students, and casual readers can review content without a network connection. This launch underscores Google’s push to make AI more useful and available across devices. Google may share more details about these apps during the I/O keynote on May 20th, showing how AI will shape future tools. The arrival of these apps marks a step forward for NotebookLM and for mobile AI research assistants.
