Three years ago we launched NotebookLM as an experimental AI product from Google Labs to help you understand anything. 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. Today we’re introducing across the board upgrades to NotebookLM that deliver new agentic capabilities in chat and more advanced reasoning to tackle the most complex research projects.
An upgraded, more thoughtful chat experience
First, we’re upgrading NotebookLM to run on Gemini 3.5 and Antigravity providing even more accurate and reliable information along with better visibility into the thinking process.
Each notebook is now equipped with a secure cloud computer, enabling NotebookLM to write and run code useful for helping you perform 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.
In our side-by-side evaluations against our prior system, the upgraded NotebookLM achieved an average win rate of over 65% (a 15% point margin above parity) across our top five core evaluation dimensions. The system demonstrated substantial improvements in large document analysis, securing a 69.9% win rate and achieved exceptional performance in advanced web research and source discovery reaching a 78.2% win rate against our prior baseline.
