Meta’s new Muse AI agent app overtakes ChatGPT as top iPhone app

AI-summarised brief · reviewed before publication

Meta’s newly released Muse AI agent app has climbed to the top of the free iPhone charts in the U.S. App Store, surpassing OpenAI’s ChatGPT. Launched earlier this month, Muse has gained traction beyond its initial release, with recent installs driving it to number one. Meta extended Muse’s availability to Mac the day before, though the desktop version does not affect App Store rankings. The app’s agentic design mirrors SpaceXAI’s Grok Bot, offering a conversational interface with personified agents.

💡 Why It Matters

  • · The shift signals a competitive edge for Meta’s AI strategy, positioning Muse as a leading alternative to established chatbots.
  • · It underscores the growing importance of agentic AI experiences in consumer app ecosystems.
