Meta's Muse AI Agent Hits No. 1 on Apple App Store, Passes 900,000 Downloads
News Summary
Meta's new personal AI agent app, Muse, has climbed to the No. 1 spot on the free-app chart of the US Apple App Store, overtaking OpenAI's ChatGPT roughly two weeks after its launch. The app was downloaded more than 902,000 times in its first six days, according to data cited by Bloomberg, and Meta's stock jumped more than 10% on the news, putting the company on pace for its best month in over a decade.
What Muse Is
Muse is described by Meta as "the world's first personal AI agent built for everyone." Unlike a conventional chatbot that only answers questions, Muse is designed to carry out multi-step tasks on a user's behalf: sending emails, booking travel, filling out web forms, comparing and lowering bills, drafting plans, converting recipe videos into grocery lists, and sending invitations. The agent operates inside a dedicated environment called Muse Secure VM, a sandboxed virtual computer with its own browser that lets it open pages, click through forms, and complete purchases while the user is away from the app. The underlying model is referred to internally as Muse Spark, and the project comes out of Meta Superintelligence Labs, the research group Meta formed earlier this year to accelerate its AI roadmap.
Launch Timeline
Meta introduced Muse on September 8, 2026 (Pacific Time), initially rolling it out to US users 18 years of age and older. Within two days, the app had already climbed to No. 2 on the US App Store free chart, according to TechCrunch. By September 21 (Eastern Time), multiple outlets including Bloomberg, CNBC, and 9to5Mac confirmed Muse had reached the No. 1 position, pushing ChatGPT to second place. Download totals reported at that point exceeded 900,000, ahead of the roughly 773,000 downloads Meta's earlier general-purpose Meta AI app recorded over a comparable post-launch window.
Availability and Pricing
Muse is available as a standalone app for iOS and Android, through a web client at muse.ai, and inside WhatsApp. Meta has said support for its AI-enabled glasses hardware is coming in a future update. The rollout is currently limited to the United States, with the company indicating additional countries will be added over time. Muse offers a free tier alongside two subscription plans: a $20-per-month "Power" tier and a $100-per-month "Maximum" tier, both aimed at users who want higher usage limits or faster task completion for more complex, multi-step agent work.
Market and Industry Reaction
The chart-topping debut arrived at a moment when investors have been closely watching whether Meta's heavy AI infrastructure spending would translate into consumer traction. Meta shares rose more than 10% in the days following the App Store milestone, with several analysts pointing to Muse's download numbers as early evidence that the company's AI investments are starting to resonate with everyday users rather than only enterprise or advertising customers. Coverage from CNBC compared Muse's early download trajectory favorably against rival agent-style products from OpenAI, xAI's Grok, and Anthropic's Claude, though analysts cautioned that chart position after a high-profile launch does not guarantee sustained daily engagement, and that agentic features handling payments and personal data will face continued scrutiny over trust, privacy, and reliability as the user base grows.
What Comes Next
Meta has signaled it plans to widen Muse's availability beyond the US and to expand integration with its hardware line, including smart glasses. Analysts and reporters covering the launch say the next signals to watch will be retention and daily active usage figures rather than download counts alone, since agentic assistants that complete real-world tasks such as purchases and bookings carry a higher bar for user trust than conversational chatbots.
