Do Better Research with NotebookLM (blog.google)

Google has enhanced its experimental AI research tool, NotebookLM, with significant upgrades aimed at improving user experience and research capabilities. Now powered by Gemini 3.5 and Antigravity, NotebookLM offers a more thoughtful chat interface and boasts over 100 curated software skills, enabling it to perform complex analyses and assist in deeper research. The update resulted in a notable performance boost, with an average win rate of over 65% in core evaluation dimensions, including a 78.2% win rate in advanced web research compared to its predecessor. Importantly, users can now begin their projects with loose ideas rather than needing established sources. This includes features like generating comprehensive outputs in various formats—such as PDFs, Excel sheets, and data visualizations—tailored to user instructions. NotebookLM can even assist in sourcing relevant information from the web, providing researchers, technical professionals, and small business owners with valuable tools to streamline their workflows. Available globally for Google AI Ultra and Workspace business customers, these upgrades represent a significant step forward in empowering users to leverage AI for effective, data-driven decision-making.
