Meta's Muse AI Agent Tops Apple App Store, Outranking ChatGPT in First Week
Key Takeaways
- •Meta's Muse app claimed the No. 1 position on Apple's U.S. App Store free chart one week after launch, overtaking ChatGPT, Gemini, Claude, Grok, and Microsoft Copilot.
- •Unlike conventional chatbots, Muse autonomously executes tasks such as sending emails, booking travel, filling out forms, and completing purchases, checking with users before sensitive actions.
- •The app integrates with third-party services including Spotify, Instagram, OpenTable, and users' email and calendar applications.
- •Meta Chief AI Officer Alexandr Wang confirmed the milestone on X and said the team intends to build on the momentum.
- •Because free-chart placement reflects download volume, the top ranking measures first-week reach rather than sustained engagement, leaving retention and competitor response as open questions.
Meta's personal AI agent, Muse, has climbed to the top of Apple's U.S. App Store free chart just one week after its launch, overtaking a lineup of the most prominent AI applications, including OpenAI's ChatGPT, Google's Gemini, and Anthropic's Claude.

The app outperformed several of the best-known names in artificial intelligence in the rankings. OpenAI's ChatGPT sits at No. 2, Google Gemini ranks No. 8, and Anthropic's Claude comes in at No. 13. SpaceXAI's Grok lands at No. 32, while Microsoft Copilot ranks No. 64.
Meta Chief AI Officer Alexandr Wang confirmed the milestone in a post on X on Friday. “A week after launch, Muse is now the No. 1 app in the App Store!” he wrote.
What Makes Muse Different From a Chatbot
Unlike a standard chatbot, Muse is built to take action on a user's behalf. It can send emails, book travel, fill out forms, complete online purchases, and even find a dog sitter. Meta says the app can be used by anyone, with no technical experience required.
Once a user sets a goal, Muse builds a plan and begins working toward it independently. The app can keep running in the background even after it has been closed, and before carrying out any sensitive actions, it checks in with the user for approval.
Muse also remembers user preferences over time, allowing it to become more personalized with repeated use.
Services and Integrations
Muse connects to a range of third-party services, including Spotify, Instagram, OpenTable, and a user's email and calendar applications.
According to Meta, the app can negotiate on a user's behalf, open a browser, and coordinate time and resources to help achieve larger objectives. The company describes Muse as capable of handling both everyday tasks and what it calls “big audacious goals.”
Early Signal for Consumer AI Agents
The No. 1 ranking is an early indication that consumer interest in AI agents is growing. Agents go beyond answering questions by actually doing things for users. Because free-chart placement is driven by download volume, the standing is best read as a measure of first-week reach — one of the few public, real-time signals available in a market where AI companies rarely disclose usage figures.
Meta's frontier AI models have lagged behind those of OpenAI and Anthropic on some key benchmarks, but Muse's App Store performance suggests the company is making progress in the consumer AI space.
The app's ascent to the top of the charts within a week of launch puts pressure on competitors such as OpenAI, Google, and Microsoft to keep pace in the personal AI agent market. What remains to be seen is whether the early download surge converts into sustained engagement, a metric that chart position alone does not capture, and how quickly rivals respond in a category that is still taking shape.
Wang said the team is looking forward to building on the momentum, noting how quickly users have found ways to put the app to work.
