A little-known AI notebook tool from Google is going viral for its Audio Overviews that mimic the speech cadence of podcasters. Here’s how to try it out.

A Google research tool called NotebookLM has been going viral thanks to a feature that transforms text documents into lively podcast-style conversations. Why it matters: Businesses see AI's future in its power to streamline work processes — but the public keeps getting hooked by its ability to impersonate humans.

Google NotebookLM product leader Raiza Martin says her team will be adding new updates to allow users to control more of the Audio Overviews.
