Google has announced an update to its NotebookLM research tool, which includes new features and the shift to Gemini 3.5 as the default model. The update allows users to start a chat about a project and build a knowledge base by suggesting different sources using its research skills and Google Search.
The feature could help users get primary sources in other languages or find new material from related authors. Previously, NotebookLM required users to bring their own sources to start building a knowledge base.

The updates are available to Google AI Ultra users and all Workspace business customers with AI Ultra Access and AI Expanded Access, with the aim of expanding them to others.
