Meta's Muse AI Tops iOS Free Apps, Outselling ChatGPT in Early Downloads

Meta’s Muse AI personal agent quickly vaulted to the top of the U.S. iOS free-app charts, outpacing OpenAI’s ChatGPT with about 730,000 downloads in five days and more than 2.5 million total since its Sept. 8 launch. Powered by Meta’s Muse Spark models, Muse competes with Claude and Grok and is offered with optional paid tiers as Meta pushes into the AI-agent market. The rollout has drawn attention to safety and privacy debates, with Amazon blocking Muse’s access to its shopping site while Shopify teams up to enable agentic checkout.
