One Useful Thing
Wharton professor Ethan Mollick on how to actually use generative AI in work, education, and everyday life.
One Useful Thing is the newsletter of Ethan Mollick, an associate professor at the Wharton School who has become one of the most widely read voices on practical generative AI. Each issue documents his hands-on experiments with frontier models — GPT, Claude, Gemini, and others — and translates what they can and can't do into concrete advice for workers, managers, students, and educators.
Mollick mixes academic research with reproducible prompts and screenshots, helping readers build accurate intuitions about LLMs without the hype or doom that dominates much AI coverage. The newsletter is essential reading for anyone trying to figure out how to integrate AI into their work, and pairs naturally with his bestselling book Co-Intelligence.
