What’s happened? Google is turning NotebookLM into a more serious research tool. The latest update adds Deep Research plus support for the kinds of files that usually live in your Drive instead of your downloads folder. According to a Google blog post, Deep Research can browse hundreds of sites, follow a plan based on your question, then return a structured, source-grounded report.
You can drop that report and its sources straight into a notebook, then use features like Audio or Video overviews to pull out big ideas.
NotebookLM now accepts Google Sheets, Drive files via URL, images, PDFs stored in Drive, and Microsoft Word (.docx) documents, with the rollout hitting all users over the next week.
