Overview
- Deep Research creates a plan, browses the web on the user's behalf, and returns a source-grounded report that can be added to a notebook.
- Users can select Fast Research for quick lookups or Deep Research for in-depth analysis, with a research plan shown before the search begins.
- Reports generate in the background so users can continue working and add more sources while results are compiled.
- NotebookLM now supports Google Sheets, Drive URLs, PDFs from Google Drive, and Microsoft Word (.docx) files, with image uploads coming in the next few weeks.
- The agent is tied to Google's Gemini and can draw context from Workspace surfaces such as Gmail, Drive, and Google Chat.
