The 2025 Google I/O conference marked a significant milestone with the launch of the NotebookLM mobile app, bringing the company’s powerful AI-driven note-taking and research assistant to Android and iOS devices. Previously limited to desktop access since its debut in mid-2023, NotebookLM now enables users to interact with their documents, PDFs, and online content on the move, leveraging Google’s Cloud and AI technologies. This shift caters to growing demand for greater flexibility and multitasking capabilities, reflecting evolving user expectations for seamless mobile experiences in productivity tools.
Key features transforming NotebookLM’s user experience on mobile
Google designed the NotebookLM mobile app to address several specific use cases faced by professionals and knowledge workers, delivering a user experience optimized for mobility and offline accessibility.
- Audio Overviews with offline playback: Users can download AI-generated podcast-style summaries of their documents for listening without an internet connection, unlocking productivity during commutes or low-connectivity environments.
- Background audio support: Playback continues uninterrupted while multitasking across other apps, crucial for maintaining workflow flexibility on mobile devices.
- Content sharing integration: Directly add web pages, PDFs, and YouTube videos into NotebookLM via the native share menu, simplifying the research and note aggregation process.
- Interactive AI hosts: Live questions and conversational redirection during audio sessions empower users to dive deeper into content with contextual AI assistance.
| Feature | Description | Benefit |
|---|---|---|
| Audio Overviews | AI-generated spoken summaries of uploaded content | Enables learning on-the-go without needing internet connectivity |
| Background Playback | Continuous audio playback while using other apps | Supports multitasking during commutes or workflows |
| Content Sharing | Direct import of URLs, PDFs, and YouTube links | Simplifies the capture of relevant data for research purposes |
| Interactive AI Hosts | Real-time conversational control over audio summaries | Personalizes comprehension through contextual engagement |
Performance insights and initial limitations on mobile platforms
While the mobile app’s user interface aligns well with Google’s Material Design philosophy, delivering a clean and intuitive experience, early testing revealed certain performance inconsistencies. Users may encounter difficulties adding URLs as sources, often receiving ambiguous error messages such as “Could not add source.” These unexplained failures limit troubleshooting capabilities and potentially hinder content ingestion workflows.
Additionally, switching between notebooks may occasionally trigger loading delays with persistent messages like “Could not load notebooks” or extended wait times without clear resolution. Such hiccups affect the app’s real-time responsiveness, particularly for users accustomed to the desktop version’s faster operation.
- Inconsistent URL content addition and lack of detailed error feedback
- Delayed notebook loading and occasional failure to switch contexts smoothly
- Suboptimal responsiveness during summary generation and UI transitions
- Reliable offline playback does confirm robustness of audio features
