Limits overview
NotebookLM applies usage limits to notebooks, sources, chats, and generated outputs based on your Google Workspace edition or AI add-on. These caps determine how many notebooks you can create, the number of sources per notebook, and daily limits for features like Audio Overviews and Deep Research.
Universal for all users with a work or school account, though limits vary. Business Starter and Frontline editions receive standard access, while Business Standard, Enterprise, and Gemini add-on users get higher capacity. AI Expanded and Ultra Access tiers provide the highest available limits.
Check your current limit tier by opening NotebookLM in a browser and looking for a Pro, Plus, Expanded, or Ultra badge next to your profile image. Detailed limit breakdowns for each tier are available in the Google Help Centre.
