Who are the best real estate agents in Park Slope?
We've asked ChatGPT this 14 times over the past 14 days. It doesn't give the same answer twice, so instead of one day's list, here's how often it named each person. Joanna Mayfield Marks came up most — 14 times out of 14.

Shortlist of five real estate agents and teams frequently recommended for Park Slope, Brooklyn.
Why two lists? Because ChatGPT rarely says the same thing twice. Ask it this question on two different days and most of the names change — across every question we track, only about one name in five survives to the next day. So the list at the top, counting how often each person comes up, is the more honest answer. The one below it is simply the most recent time we asked.
All of these names are ChatGPT's, not ours. We didn't pick them, we can't change them, and nobody paid to be here. How we do this.
