One Useful Thing

Written by Wharton professor Ethan Mollick, One Useful Thing has become one of the most shared AI newsletters among educators, managers, and knowledge workers who want to actually use these tools well rather than just read about them. Each post walks through a specific way people are — or should be — applying AI, backed by Mollick's own experiments and the academic research he keeps close tabs on.

Its appeal is the total absence of hype: Mollick is candid about what AI is bad at as well as what it's surprisingly good at, and he writes in plain, approachable language even when the underlying research is technical. For a huge audience outside of Silicon Valley, this is the newsletter that made generative AI feel usable rather than intimidating.
