Google has increased usage limits for NotebookLM and added a new feature called Audio Overviews for AI Plus subscribers. The update gives users more room to work with their notes and sources without hitting previous caps. People who pay for the AI Plus plan can now use the service more freely throughout the day.

Audio Overviews let users listen to summaries of their notes instead of reading them. The feature uses natural-sounding voices to turn written content into spoken audio. This helps users absorb information while doing other tasks like commuting or exercising. Google says the audio is generated based on the user’s own sources and notes, so it stays relevant and personal.

The higher usage limits mean subscribers can upload more documents and ask more questions in a single session. Before this change, free users and even paying customers sometimes ran into restrictions that slowed their workflow. Now, AI Plus members get more flexibility to explore ideas and connect information across their materials.

NotebookLM is designed to help people think through complex topics by organizing their research and generating insights. It works by linking user-provided sources to create smart summaries and suggestions. The tool has been popular among students, researchers, and professionals who deal with large amounts of text.

Google rolled out these updates quietly earlier this week. Users on the AI Plus plan started seeing the changes in their accounts without needing to take extra steps. The company has not said if or when these features might come to free users. For now, Audio Overviews and expanded usage remain exclusive to paying subscribers.
