Meta will use your AI chats to target ads — here’s what to do before December 16

Meta’s AI assistant is about to get a little more personal, and probably not in the way you're expecting.

Beginning December 16, 2025, the company will use conversations you’ve had with its chatbot to personalize ads across Facebook, Instagram and other Meta apps. This means that if you ask Meta AI about the best running shoes, don’t be surprised if those running shoes and running apparel show up in your feed later.
