Google Rebrands NotebookLM to Gemini Notebook

Google has officially rebranded its AI-powered research assistant, NotebookLM, as Gemini Notebook. This transition marks the latest step in Google’s strategy to consolidate its experimental AI projects under the primary Gemini brand. The tool, which first debuted at Google I/O 2023 under the codename “Project Tailwind,” has evolved from an experimental offering from Google Labs into a widely utilized platform. According to company reports, the service now supports over 30 million people and more than 600,000 organizations, ranging from students converting notes into audio and video summaries to business owners creating interactive onboarding materials.

While the service is being integrated more deeply across Google Search and the broader Gemini ecosystem, the company confirms that Gemini Notebook will remain a standalone product. To reflect this new identity, the application’s logo is being updated to feature a blue/purple Gemini gradient. The product was originally launched three years ago to help users “understand anything” by serving as a collaborative knowledge and research partner that helps organize thinking and identify connections across documents.

Alongside the name change, Google is rolling out significant under-the-hood performance improvements. The platform has been upgraded to run on the Gemini 3.5 model, which Google claims provides “even more accurate and reliable information along with better visibility into the thinking process.” A major addition to the tool’s capabilities is the integration of “Antigravity,” Google’s coding tool. This technology allows each notebook to utilize a “secure cloud computer,” enabling the AI to write and execute code natively to perform complex data analysis.

These new agentic capabilities allow the tool to handle more advanced reasoning tasks. By leveraging the secure cloud computer, the platform can now generate PDFs, spreadsheets, presentations, charts, and images directly. This update is designed to make complex research projects easier to complete by allowing the AI to perform deeper research and more intricate calculations that were previously unavailable. While these features are rolling out globally, specific access to the cloud-based code execution is currently designated for Google AI Ultra and Workspace business customers.

The update also includes support for more file types and streamlined web source integration. By infusing coding execution for data analysis, Google aims to make the tool more interactive. The shift to the Gemini 3.5 model is intended to provide users with a more robust research assistant that can synthesize and summarize documents more effectively. As stated in the official announcement, these upgrades deliver “new agentic capabilities in chat” to tackle increasingly complex research projects and tasks.

Google’s move to rename the product is part of a trend where the company launches AI products under experimental names before eventually tying them to the Gemini brand. Despite the transition, the core objective remains consistent with the original goals set during the Project Tailwind phase: to provide a space where users can organize information and spark new ideas. The update is currently being deployed globally, ensuring that the millions of users who rely on the platform for studying and data organization have access to the latest reasoning and agentic tools.
