Google is rebranding its AI-powered research tool NotebookLM to Gemini Notebook. The update, announced Thursday, integrates the tool more deeply into the Google ecosystem while introducing advanced coding and data analysis capabilities powered by the Gemini 3.5 model and the Antigravity agentic platform for both individual and enterprise users.
From Project Tailwind to Gemini Notebook
What began at Google I/O 2023 as an experimental project under the name Project Tailwind
has officially shed its original branding. Google is renaming its research assistant NotebookLM to Gemini Notebook, a move designed to align the product with the company’s primary AI brand, according to reporting from 9to5google.
Despite the name change and a refreshed blue-purple gradient logo, the core mission remains the same. Google states that the product will continue as a standalone product focused on being your premier research tool,
but it is now being woven more tightly into the broader Google ecosystem. Users can expect their notebooks to appear within the Gemini app for better organization, with plans to integrate the tool into Google Search’s AI Mode in the near future.
Gemini 3.5 and the Secure Cloud Computer
The rebranding coincides with a significant technical overhaul. As Google detailed in its official announcement, every notebook is now equipped with a secure cloud computer.
This infrastructure allows the AI to move beyond simple text summarization by writing and executing code natively, enabling more complex data analysis grounded directly in a user’s uploaded sources.
This functionality is driven by the integration of Gemini 3.5 and Antigravity, which The Verge notes provides better visibility into the AI’s reasoning process. According to internal evaluations cited by Arstechnica, this upgraded system achieved an average win rate of 65 percent across five core evaluation dimensions, including document creation and advanced research, when compared to previous models.
Tiered Rollout and Subscription Access
Access to these advanced features is currently being staged based on subscription tiers. The cloud computer update is available immediately to Google AI Ultra subscribers and Workspace business customers who hold AI Ultra Access or AI Expanded Access.
For users on the standard Pro plans—priced at $19.99 a month—the wait will be short. Google confirmed that these upgrades will roll out to Pro users on the web over the coming weeks.
This tiered approach mirrors Google’s strategy for other high-end AI features, such as those previously restricted to the $99.99 or $199.99 Ultra plan tiers.
New Output Capabilities and Research Workflows
The upgrade introduces significant flexibility in how users export their research. Users can generate data visualizations and charts in PNG or SVG formats, compile work into PDFs, DOCX, or Markdown files, and even create structured data like CSV or JSON.
The tool’s ability to act as an agentic research companion
is perhaps the most notable shift in utility. As CNET reported, users no longer need a pre-existing repository of documents to start a project. The AI can now guide users through the discovery phase, crawling the web to find relevant sources with the user’s permission. This change aims to solve common research hurdles, such as normalizing conflicting data formats or transforming dense technical specifications into simplified slide decks and roadmaps.
With over 30 million users and 600,000 organizations already utilizing the platform, the transition to Gemini Notebook marks a pivotal attempt by Google to standardize its AI research tooling. Whether these agentic capabilities will sufficiently differentiate the product from the standard Gemini chatbot remains the primary question for power users, especially as both tools now leverage the same underlying model architecture.
