Google has officially announced the release of the iOS version of its AI-powered note-taking and research assistant tool, NotebookLM, which is now available simultaneously with the Android version. This announcement comes just ahead of the Google I/O 2025 Developers Conference, marking a significant expansion for NotebookLM from desktop to mobile platforms, providing users with a more convenient cross-platform research experience. Below is the latest information curated by AIbase to help you gain a deeper understanding of the highlights and features of this new mobile application.
Since its initial launch in 2023, NotebookLM has become an invaluable assistant for students, researchers, and professionals thanks to its intelligent summarization, semantic search, and audio overview (Audio Overviews) functionalities. However, until now, the tool was limited to desktop browsers only, making the absence of a mobile app one of the most frequently requested features from users. In response to user demand, Google has officially released the NotebookLM mobile app on both the iOS App Store and Google Play Store. The iOS version supports iPhones and iPads running iOS17 or higher, while the Android version is compatible with devices running Android10 and above.
The newly launched mobile app retains the core functionalities of the desktop version, allowing users to create and browse notebooks anytime, anywhere, and upload diverse sources such as websites, PDFs, or YouTube videos. Thanks to cross-platform synchronization, notebooks and resources created on the desktop can seamlessly transition to the mobile device, ensuring uninterrupted workflow.
Core Functionality Optimization, Enhanced Mobile Experience
Convenient Sharing and Uploading
The design of the NotebookLM mobile app fully considers mobile usage scenarios. Users can easily add content from other applications (such as browsers or YouTube) directly into NotebookLM as research material via the sharing feature on iOS and Android devices. This significantly simplifies the process of collecting information, making it ideal for conducting research during commutes or fragmented time periods.
Audio Summaries Anytime, Anywhere
NotebookLM’s signature feature—audio summaries (Audio Overviews)—is also fully supported on mobile. This function converts complex documents into audio summaries similar to podcasts, taking only 10-20 seconds to generate, with complete playback control options including double-speed playback. Whether during commutes or in between meetings, users can efficiently digest research materials.
Tablet Optimization and Interface Design
To enhance the tablet experience, NotebookLM adopts a two-column layout on iPads and Android tablets, enabling users to view sources and interact with AI simultaneously, improving productivity. Additionally, the app automatically switches between light and dark modes based on the device's system settings, offering a friendly and adaptable interface.
Technical Upgrade, Powered by Gemini2.5Flash
The launch of the NotebookLM mobile app accompanies technical upgrades. Google confirmed that NotebookLM has fully integrated the Gemini2.5Flash model, significantly enhancing its ability to handle complex multi-step reasoning problems. Although the audio summary functionality remains unaffected by this upgrade, the overall text interaction capabilities have been further optimized in terms of comprehensiveness and accuracy.
It is worth noting that Google also introduced the NotebookLM Plus advanced subscription service, accessible through Google One AI Premium or Google Workspace plans, unlocking additional premium features such as higher quotas and exclusive support. According to AIbase, Google offers free NotebookLM Plus and Gemini Advanced subscription services to U.S. college students until the end of the spring semester in 2026.
A Future-Oriented Mobile Research Ecosystem
While launching the NotebookLM mobile app, Google clearly stated that it will continue to iterate over the next few months, adding more features and optimizations. Based on the latest developments at Google I/O 2025, AIbase predicts that NotebookLM may further integrate AI technologies within the Google ecosystem, such as the Gemini series models, to provide users with a more intelligent research experience.
Currently, the NotebookLM iOS version is already available on the App Store, where users can download and experience it directly; the Android version is also live on Google Play Store, though some devices may need to retry installation later due to compatibility issues or consider side-loading via APKMirror.
