NotebookLM is one of Google’s best AI tools. The company keeps making it better and recently added support for more sources, interactive images, the ability to generate infographics and Slide Decks from the added sources, and more. Now, Google is giving its most serious users an extra boost by making NotebookLM a part of its AI Ultra plan.
If you pay for Google’s AI Ultra tier, you’ll now be entitled to extra benefits in NotebookLM. Besides priority and highest access to the latest Gemini models, NotebookLM in Ultra tier expands the usage limit to 50x more generations vs. the regular plan.
Notebook size gets a major upgrade, too, with support for up to 600 sources per notebook, compared to just 50 on the free plan and 300 on Pro. Limits for features like Audio and Video Overviews and Slide Decks have also been increased.
More importantly, Google says AI Ultra subscribers will get priority access to features such as watermark removal on Slide Decks and Infographics, along with the return of the Long option for Slide Decks.
Previously, NotebookLM offered the same limits and features for AI Pro and Ultra users. That never quite made sense, given the Ultra plan costs a steep $200 per month — about 10x more than AI Pro.
If you already pay for Google AI Ultra, you can now enjoy the Ultra experience in NotebookLM as well, at no extra cost.
The AI Ultra plan comes with several other perks to justify its high subscription price. It’s primarily meant for power users and provides priority and highest access to Gemini models in the Gemini app, Google Search, Jules, Gemini Code Assist, and Google Antigravity.
Other perks include early access to Project Mariner, ad-free YouTube viewing with the Premium individual plan, 25,000 monthly credits for use across Flow and Whisk, and 30TB of Google account storage with family sharing support.
Given its usefulness, Google should consider offering standalone plans for NotebookLM that are not linked to its AI plans. Or, it should allow users to upgrade their limits in NotebookLM and unlock additional features through a paid add-on.
