Meta has launched AI Mode on Facebookan AI-powered search tool that pulls answers from public posts across Groups, Reels, and Marketplace listings. The feature is now live on the Facebook mobile app for US users and uses Meta AI to generate conversational answers instead of returning traditional link-based search results.
How AI Mode works
AI Mode sits inside Facebook’s existing search bar, appearing as a toggle next to familiar tabs like People, Posts, and Marketplace. When users ask questions in natural language, Meta AI synthesizes responses from public content rather than returning a list of links. The system can recommend products from Marketplace, surface advice from Group discussions, and pull clips from Reels that match the query.
Powered by Muse Spark model
AI Mode runs on Meta’s Muse Spark modelwhich synthesizes responses from what real Facebook users have written—think forum-style advice, event recommendations, or product tips surfaced from public posts. Meta positions this as an advantage: answers rooted in lived experience rather than generic web results.
Sources and content
The feature draws specifically from user-generated content that is publicly posted, such as Group discussions, short-form video captions in Reels, and public posts from Facebook, Instagram, and Threads. Meta’s AI can cite public posts to provide richer responses rooted in what people are talking about now.
Rollout and availability
AI Mode is rolling out now to users in the United States on the Facebook mobile app. A UK launch timeline and any web or desktop version have not been confirmed by Meta. The rollout is described as global and immediate, with no phased launch or beta testing period mentioned—it’s live now for anyone who searches on Facebook.
Privacy and concerns
The feature raises immediate questions about reliability, as it draws from whatever users have publicly written—including misinformation. Unlike search engines that weight authoritative sources, AI Mode draws from everyday user posts rather than vetted sources. Additionally, there is no opt-out mentioned for excluding your public posts from AI indexing, meaning every public post you’ve made can now fuel AI responses served to millions of other users.
