Meta launches AI Mode in Facebook, an AI search across posts, Groups, and Reels

Meta has announced the launch of AI Mode in Facebook, an AI-powered search mode that generates answers by analyzing users' public posts, including posts from groups and short-form Reels videos.

How AI Mode works in Facebook

Instead of the usual keyword-based list of links and posts, AI Mode analyzes the content of the platform's public posts and assembles a coherent answer to the user's query. Its sources include not only personal posts but also community (group) content and the Reels feed — formats that were previously indexed and surfaced far less readily than the regular feed.

• The feature is called AI Mode and launches inside Facebook search
• Answers draw on public posts, group posts, and Reels videos
• The goal of the update is to change how people find information and engage with content on the platform
• The feature is developed by Meta

Why Meta is changing Facebook search

Facebook is one of the few major social networks where full content search has long been a weak spot: users more often turned to third-party search engines to find what they needed, or failed to find relevant posts and group discussions at all. Bringing generative AI into search is meant to fix this — instead of sifting through links, users get a ready-made answer assembled from scattered posts.

This is part of Meta's broader strategy to bring its own AI assistant, Meta AI, built on the Llama model family, into all of its products — from Facebook and Instagram to WhatsApp and Ray-Ban Meta glasses. Other major players are already testing similar AI search features for platform content: Google is building AI Mode and AI Overviews into its search results, while OpenAI and Perplexity are developing their own search products based on large language models.

What problem Meta is solving

Groups remain one of the most active yet least searchable parts of Facebook: millions of discussions, tips, and recommendations inside private and public communities were effectively not indexed by regular search and got lost in the stream of new posts. The same goes for Reels — short videos are hard to find through text search on their descriptions. AI Mode is supposed to learn to "read" content in these formats and turn scattered mentions into a concrete answer — for example, gathering product recommendations or community opinion from dozens of posts across different groups into a single coherent text.

Facebook has tried to improve search before: for years the platform offered basic full-text search across friends' posts and public Pages, but it fell noticeably short of dedicated search engines in quality and usability, and couldn't handle tasks like "what do people think about X" or "what recommendations were given in this group." The move to generative AI Mode is an attempt to close that gap using the same approach Google and Perplexity already use: instead of returning a list of links, deliver a substantive answer right away.

What this means

Generative search is steadily becoming a standard feature of major platforms — not just in standalone search engines but inside social networks themselves, where users previously had to settle for a chronological feed or simple keyword matching. For Facebook, it's an attempt to revive users' interest in searching groups and communities, which have long been the least visible part of the platform.
