Meta to tune Facebook and Instagram ads with AI conversations

Mexico’s El Universal reports that Meta is starting to use people’s interactions with its Meta AI tools to refine both content recommendations and ad targeting across Facebook and Instagram. Beginning December 16, 2025, posts, Reels and sponsored messages will be increasingly aligned with the topics users explore in AI chats, effectively turning assistant prompts into an additional signal for the recommendation engines. Meta says it has been notifying users since October via in‑app alerts and email, and stresses that more than a billion people already use Meta AI each month. The company is pitching the move as a way to make AI features feel more relevant, but it also blurs the line between “assistant” and adtech in a way some users may find uncomfortable. As platforms race to monetize chat‑based AI, this kind of quiet data‑fusion is likely to become a flashpoint in future privacy and competition debates.
