Google's AI note-taking tool NotebookLM has received a major update, significantly expanding the permissions for Ultra members. This move highlights the growing trend of AI-assisted productivity tools focusing on high-end users. As an intelligent note-generation platform, NotebookLM's latest upgrade not only enhances its generation capabilities but also improves the user experience, helping professionals and creators efficiently handle complex information.

 Generation limit increased 50 times, bidding farewell to bottlenecks

Compared to the free version, the generation limit for Ultra members has been increased to 50 times the original. This adjustment directly addresses the limitations faced by free users in high-intensity usage scenarios, such as batch generating reports or analysis documents without frequent interruptions. After the upgrade, users can process large volumes of data more smoothly, significantly improving work efficiency, especially for researchers and content creators.

 Access to top-tier Gemini model, smart upgrade

Ultra members now have access to the highest-level Gemini model for the first time. This advanced AI core brings more accurate semantic understanding and generation capabilities, such as providing deeper insights and personalized outputs in note summaries or creative brainstorming. The powerful computing power of Gemini will transform NotebookLM from a simple tool into an intelligent assistant, comparable to professional AI workstations.

 Notes sources expanded to 600, greatly increasing data inclusiveness

The permission to add up to 600 note sources allows Ultra users to integrate more diverse inputs, such as PDFs, web clips, or multimedia files. This expansion greatly enriches the knowledge-building process, enabling users to easily create cross-disciplinary, large-scale note systems, suitable for academic research, corporate reports, or personal knowledge management.

 PPT generation optimized, long format options unlocked

The PPT generation feature now includes a "long" setting option, supporting the creation of more detailed multi-page presentations. This improvement is designed for scenarios requiring in-depth content presentation, such as business proposals or academic lectures, allowing users to instantly generate structured, logically clear long PPTs and save hours of manual editing time.

 Watermark removal, output with a professional touch

Ultra members can now freely remove watermarks from PPTs and infographics, ensuring the output content is clean and professional. This feature is particularly suitable for commercial and publishing needs, avoiding brand logos interfering and enhancing the quality of the final product.

This expansion of NotebookLM's permissions reflects Google's strategic intent in building its AI ecosystem: by adopting a tiered subscription model, it aims to boost loyalty among high-end users and drive the tool toward enterprise-level applications. AIbase analysts point out that this update may further widen the gap between free and paid versions, likely attracting more professional users to the Ultra plan.
