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.

It’s a sad, funny, and often unnerving listen, especially when the male presenter talks about phoning his wife after learning that he’s only an AI, to find that she didn’t exist and the number he was phoning wasn’t even real. There are shades of a Black Mirror episode to the whole thing!

NotebookLM from Google can use AI to summarize and query multiple documents on one topic—and you can even turn your notes into Audio Overviews, customized podcasts.
