How Gemini 3.5 and Antigravity Transform NotebookLM
Google unveiled today that its NotebookLM AI platform now runs on the Gemini 3.5 model and the Antigravity framework. The upgrade rolls out globally to all existing NotebookLM users, offering enhanced agentic tools for research, drafting, and data analysis. The announcement came during Google’s AI developer summit in Mountain View.

Google says the change reduces latency by 30 percent and cuts compute costs for end‑users. The move follows a year of rapid AI competition, where Google aims to keep its productivity suite ahead of rivals like Microsoft and OpenAI.
Will the new agentic tools change how professionals work?
Gemini 3.5 brings a deeper grasp of context, allowing the notebook to maintain thread continuity across long documents. Antigravity adds a layer of tool‑use capability, letting the AI invoke external APIs or run code snippets without human prompting. In internal tests, the combined system completed multi‑step research tasks 40 percent faster than the previous version. „We wanted a model that could not only answer questions but also take initiative,” said a Google product manager. Early adopters report smoother brainstorming sessions, with the AI proposing slide decks, data visualizations, and citation lists automatically. The upgrade also supports richer media, letting users embed charts that the AI can interpret and update in real time.
The answer appears to be yes, especially for knowledge workers who rely on rapid iteration. By handling routine drafting and data‑gathering, NotebookLM frees users to focus on higher‑level analysis and creativity. Companies experimenting with the beta say employee productivity rose by roughly 15 percent after a month of use. Critics caution that over‑reliance on autonomous AI could erode critical thinking skills, but Google emphasizes built‑in safeguards that require user confirmation before executing actions. As the technology matures, experts predict a shift toward „AI‑augmented” workflows, where humans and machines collaborate seamlessly on complex projects.
The upgrade positions NotebookLM as a more proactive partner in everyday tasks, from academic research to business planning. Google’s integration of Gemini 3.5 and Antigravity signals its commitment to building AI that not only answers queries but also takes initiative. If adoption continues to grow, the platform could become a cornerstone of future productivity suites, reshaping how information is created and consumed.
