NotebookLM

Developed by Google Labs, built on Gemini; lets users turn uploaded documents into summaries, study guides, mind maps, and audio/video "overviews" grounded in cited sources rather than open-ended generation. Sourcing during research found Google's own product page now referring to it as "Gemini Notebook (formerly NotebookLM)" — flagging this brand transition since the NotebookLM name is still the dominant search term as of this sourcing pass. Shares Google's Workspace-wide status dashboard, same surface already used for the Gemini catalog entry. No standalone public developer API.
