NotebookLM

Overview

NotebookLM lets you collect documents, web pages and other sources into a notebook, then ask questions that are answered from those sources with citations back to the original text. It can also produce summaries, study guides and audio overviews that narrate the material in a conversational format. It is built for students, researchers and writers who have a defined body of material and want to query it closely. Because answers come from what you uploaded, it is less useful for open-ended general knowledge. Source and usage limits apply, and features and availability have changed over time, so check Google's current details.
