Google just fused NotebookLM's coolest trick right into Search
Google Search now has audio recaps for you

NotebookLM might be one of Google’s smartest tools you’ve barely used. It first made waves—not for its research chops—but for its Audio Overviews feature. Instead of dumping information at you, it turns your source material into podcast-style recaps that actually sound like real people talking, not robots reading a script. After popping up in the Gemini app and Discover’s Daily Listen, Google is now testing these AI-driven audio recaps right on the front page of mobile Search.
