Google Rebrands NotebookLM to Gemini Notebook, Brings Gemini 3.5 and Antigravity to AI Pro

Google renamed its NotebookLM research tool to Gemini Notebook and announced an upgrade bringing Gemini 3.5 with Antigravity code execution to AI Pro subscribers.

The Gemini 3.5 and Antigravity combination, which began rolling out to AI Ultra users last month, will arrive for AI Pro subscribers "over the coming weeks." According to Google, the Antigravity feature provides each notebook with a secure cloud computer to write and execute code natively for "complex data analysis grounded in your sources."

What Changes with the Rebrand

The new Gemini Notebook name replaces "NotebookLM," eliminating the "language model" terminology. Google updated the logo to feature a blue/purple Gemini gradient, explicitly tying the product to its main Gemini brand.

Gemini Notebook remains a standalone research tool but will "do more across the Google ecosystem." Notebooks are already available in the Gemini app for chat organization. Google announced they will soon appear in Google Search's AI Mode.

Usage Numbers

Google claims Gemini Notebook now has over 30 million users and more than 600,000 organizations using the platform. The tool originated as Project Tailwind at Google I/O 2023 before launching as NotebookLM.

Technical Capabilities

The Gemini 3.5 upgrade with Antigravity enables what Google describes as "entirely new output formats and deeper analysis." The code execution capability allows the system to perform data analysis tasks directly within the notebook environment, grounded in user-provided sources.

AI Ultra subscribers received access to these capabilities starting last month. The expansion to AI Pro subscribers represents a broader rollout of the code execution functionality.

What This Means

The rebrand signals Google's consolidation strategy around the Gemini name, moving away from product-specific AI branding. The 30 million user claim, if accurate, positions Gemini Notebook as one of Google's more successful AI products. The staggered rollout of Gemini 3.5 with Antigravity to AI Pro (after AI Ultra) suggests Google is testing the code execution infrastructure at scale before full deployment. The upcoming integration with Google Search's AI Mode indicates Google plans to make research capabilities available across more of its product surface area.
