NotebookLM's standout feature is audio overviews

NotebookLM introduced audio overviews to convert note content into podcast-style summaries. The feature allows users to listen to condensed, spoken versions of their notes. Google enhanced the functionality to improve clarity and context retention. Audio overviews now support multiple note types and are accessible within the NotebookLM app. The feature improves user engagement by enabling hands-free review of learning content.
