Meta's AI Agent 'Muse' Tops US App Store Free Chart, Surpassing ChatGPT

Meta's new AI agent application, Muse, reached the number one spot on the US App Store free apps chart approximately ten days after its September 8, 2026, launch. Unlike traditional chatbots, Muse is designed to perform tasks such as research, form filling, and online booking by integrating with third-party services like email and calendars. The app operates within a secure virtual machine and offers both free and subscription-based tiers. While its initial growth was steady rather than explosive, its rise to the top indicates strong consumer demand for task-oriented AI agents.
