Meta's new Muse AI agent app reached #1 on both iOS and Android free charts in the US within days of launch (2.5M downloads in 13 days), significantly outpacing Claude and Grok. Unlike conversational AI assistants, Muse is positioned as an agentic tool for task automation (form-filling, email management) with cross-platform integration (WhatsApp, Gmail, Instagram Marketplace). The momentum triggered an 11% Meta stock surge. For Thai SMEs, this signals accelerating AI agent adoption in consumer and enterprise workflows—a shift from generative chat to autonomous task execution.
