It all started on a long drive from south Florida to North Carolina last holiday season. As Robert Levine drove, he asked his wife in the passenger seat to prompt ChatGPT with questions they had about the home-selling process. “Are we capable of doing this?” they asked. “What’s the realistic timeline tactically?”

The conversation started as a way to pass time on the long trip. But it soon ballooned into a comprehensive endeavor, with the AI taking over the marketing, planning, pricing, and negotiating. Through simple prompts throughout the home-selling journey, Levine and his wife clinched a signed contract to sell their Cooper City, Fla., home for $954,800—or $100,000 more than what real estate agents estimated the home’s value to be.

“When we met with real estate agents they lacked confidence in pricing,” Levine told Fortune. “ChatGPT gave us more confidence in price points of where the market was going.”

AI models are growing more capable of completing even the most complex tasks, surpassing benchmarks that the world’s smartest mathematicians and lawyers deemed onerous hurdles.

It’s not just businesses that are leveraging the technology. Everyday Americans are using AI to serve themselves, some for selling their homes, and others for more questionable practices like completing their schoolwork. Some AI experts and business leaders think the technology could wipe out swaths of white-collar workers, and real estate agents may not be spared.
