Meta is rolling out its AI assistant across 41 European countries and 21 overseas territories, marking its largest global expansion to date. The service, already used by over 700 million monthly active users worldwide, will initially offer chat functionality in six European languages through Facebook, Instagram, WhatsApp, and Messenger. Users can access Meta AI via a new blue circle icon and utilize '@MetaAI' in group chats. The platform integrates web information, content discovery, and social features, enabling users to find relevant posts, reels, and general information within a single interface.
