Google is expanding NotebookLM with a set of upgrades aimed at turning the product into a more capable research assistant. The company said the latest version adds stronger reasoning, an agentic chat experience, and a secure cloud computer that can run code inside each notebook.
NotebookLM, which Google introduced as an experimental project, has been used by millions of people and organizations to organize information, compare documents, and generate ideas. With the new changes, Google says the tool can now help users tackle more complicated research tasks, especially when the work involves analyzing data or finding supporting sources on the web.
At the center of the update is a new reasoning system built on Gemini 3.5 and Antigravity, according to Google. The company says the upgrade is meant to improve accuracy and reliability while also making the model’s thinking process easier to follow.
Google is also adding a secure cloud computer for each notebook. That environment lets NotebookLM write and run code, which can be used for data analysis and other research tasks. The system includes more than 100 curated software skills, widening the kinds of work the product can handle.
Google said internal comparisons showed the new system outperforming its previous version across core evaluation areas. The company reported particularly strong results for large document analysis and web research and source discovery, though those figures were based on Google’s own testing.
The update also broadens the types of outputs NotebookLM can create. Users can now ask the service to generate more polished deliverables, including reports with charts and tables, spreadsheets, worksheets, and slide decks.
The available export formats now include PDFs, Word documents, markdown and text files, images, structured data files such as CSV and JSON, Excel spreadsheets and PowerPoint presentations. Google says the content can be downloaded directly from the studio panel, and users can make edits after generation.
The company said it plans to add more formats later.
Another change is designed to lower the barrier to entry for people who do not already have a stack of source documents. Previously, NotebookLM was most useful when users arrived with prepared material. Now, Google says people can begin with a general question or loose idea and let the tool help them find relevant sources.
NotebookLM can search the web for relevant, high-quality material and add it to a notebook. Google says users still control what gets included, and that sources remain clearly attributed so projects stay grounded in material they trust.
Google highlighted several examples of how the new capabilities could be used. A data analyst could combine conflicting datasets from different countries, use the system to locate more context online, then generate charts and a report. A technical program manager could turn dense specifications into a simpler guide and presentation. A small business owner could compare campaign spending with sales data to help judge whether a marketing push is paying off.
The updated NotebookLM features are rolling out globally on the web starting today for Google AI Ultra users and certain Workspace business customers with AI Ultra Access and AI Expanded Access. Google says it plans to bring the changes to additional users over time.
