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

Meta’s Muse AI agent app reaching the top of the U.S. iPhone App Store underscores how quickly AI assistants are becoming mainstream consumer platforms, intensifying competition among Meta, OpenAI, Apple, and others. For CIOs and technology leaders, this signals a shift from standalone chatbots to agentic, cross-device workflows that could influence employee expectations, productivity tooling, and the vendor landscape IT must support and govern. The rise of more conversational, personalized agent interfaces also raises the stakes for integration, data privacy, and policy controls as AI assistants move closer to everyday business use.
