Google is Rolling Out a Major Update to NotebookLM

Google’s innovative NotebookLM is being updated with Gemini 3.5, Antigravity, and new chat-based agentic and advanced reasoning capabilities.

“Three years ago we launched NotebookLM as an experimental AI product from Google Labs to help you understand anything,” NotebookLM Director of Product Management Trond Wuellner and NotebookLM Software Engineer Usama Bin Shafqat write in the announcement post. “Millions of people and organizations turn to NotebookLM as a collaborative knowledge and research partner because it helps them organize their thinking, identify deeper connections across their documents and spark new ideas.”

Here’s what’s new in NotebookLM.

Gemini 3.5 and Antigravity. NotebookLM is now powered by Gemini 3.5 and Antigravity, its agent-first AI-powered integrated development environment (IDE). Google says it will now provide “even more accurate and reliable information along with better visibility into the thinking process” as a result.

Secure cloud computer. Each notebook in NotebookLM is now equipped with a secure cloud computer so it can write and run code related to performing deeper research and more complex analysis. “The system includes more than 100 curated software skills, unlocking a wide range of new capabilities to help you more deeply understand the sources in your notebook,” Google notes.

More output formats. NotebookLM can now output to data visualizations, charts, documents (PDF, Word, Markdown, text), Nano Banana-based images, structured data (csv, json), Microsoft Excel, or Microsoft PowerPoint. And Google plans to add more formats in the future.

Easier research. Until today, NotebookLM worked best when you came to it with a strong idea for the research you wanted and had source materials. But now, you can start research with vaguer ideas and questions, and NotebookLM will help you build a source repository in chat. “Perhaps you want to find primary sources in other languages to better understand new perspectives, or you’re seeking related works by an author you recently discovered,” Google notes. “It can even use Google Search to find relevant, high-quality sources from the web and add them to your notebook.”

These improvements enable new workflows, Google says. For example, researchers can use NotebookLM to combine data from different countries with conflicting formatting, and it can conduct web-based research to find additional context, analyze the data, and create charts and other documents to explain the results. Technical professionals might use NotebookLM to transform specifications and documentation into a simple guide, slide deck, or roadmap. And small business owners can use it for media campaigns, analyzing sales data, and plotting business strategies.

The NotebookLM updates are rolling out globally on the web starting today to individuals with a Google AI Ultra subscription and Workspace business customers with AI Ultra Access and AI Expanded Access. They will expand to other users soon.
