Meta has introduced AI-powered tools that let users directly shape what they see on Facebook.
The update lets people describe, in their own words, what they want to see in Feed and Reels, and Meta says the recommendations respond right away. That is a meaningful product shift because it moves personalization from hidden ranking signals to explicit natural-language control.
For creators and platform watchers, the practical takeaway is that recommendation systems are becoming more conversational and potentially more tunable. For users, it may reduce the gap between what they expect from the feed and what the algorithm actually serves.
This is also a notable consumer AI development because it puts generative-style interaction directly into a mass-market social product. The change is less about model novelty than about a widely deployed interface pattern that could spread across other platforms.
