NotebookLM evolves: Google rolls out a major update, here is what changes

▤ Summary

Google is rolling out a major web update for NotebookLM that changes how users start and complete research projects. The tool can now suggest and gather sources on its own through Google Search, including sources in other languages. It also adds export options for multiple output formats such as PDF, DOCX, Markdown, CSV, JSON, and PowerPoint, with editing available afterward. Google says the update also adds step-by-step reasoning visibility and defaults to Gemini 3.5 Flash and Antigravity for more accurate responses. The rollout starts now for Google AI Ultra and eligible Workspace Business customers, with wider availability planned later.
