Meta’s Muse AI has reached an estimated 5 million U.S. downloads within 22 days of its September 8 launch, according to market intelligence firm Sensor Tower. The milestone highlights strong early interest in Meta’s new personal AI agent, which is designed to perform tasks rather than simply answer questions.
The figure is an estimate from Sensor Tower rather than an official download number released by Meta. Muse is currently available in the United States and Canada, with both iOS and Android supported.
Muse AI Reaches the 5 Million Mark
Sensor Tower estimates that Muse reached 5 million U.S. downloads 22 days after its launch.
The firm estimates that ChatGPT took 56 days to reach the same milestone, compared with 103 days for Grok and 492 days for Claude. However, these comparisons need context because the applications had different launch conditions and platform availability. Claude and Grok, for example, were initially more restricted by platform availability, while Muse launched on both iOS and Android.
The numbers therefore demonstrate rapid early adoption for Muse, but they should not be interpreted as proof that Muse has more users or greater overall engagement than competing AI services.
What Makes Muse Different?
Muse is designed as an AI agent, meaning it can take actions on behalf of a user.
Depending on the task and available access, the assistant can browse the web, send emails, complete online forms, assist with shopping and help arrange travel. This gives Muse a different role from a conventional chatbot that primarily generates answers or recommendations.
The broader idea behind agentic AI is to allow software to handle several steps of a task after a user provides an objective.
For Meta, Muse represents an attempt to bring that type of AI interaction into a consumer-facing application.
App Store Performance Adds to the Momentum
Muse has also performed strongly in U.S. app-store rankings.
9to5Mac reported that the app had maintained the top position on the U.S. App Store for 12 consecutive days by September 30. Muse has also reached the top of Google Play in the U.S. during its early rollout.
App-store rankings, however, are a snapshot of demand and do not reveal how many people continue using an application after downloading it.
Long-term active users and retention will therefore be more useful indicators of whether Muse’s initial popularity continues.
Meta Is Promoting Muse Across Its Platforms
Meta’s own promotional activity has also played a role in Muse’s visibility.
Sensor Tower reported that Meta increased its advertising activity around Muse from September 16. The firm estimated that downloads increased 73% from the previous day as advertising activity increased.
Sensor Tower also said Muse received as much as 50% of Meta’s daily in-house advertising impressions during the September 14–27 period.
However, the data does not establish that advertising alone caused Muse’s download growth. TechCrunch reported that Meta’s advertising was one factor behind the app’s expansion, while noting that the majority of Muse’s early growth was not necessarily attributable to paid promotion.
The 5 Million Figure Needs Some Context
Sensor Tower estimates that only 23 apps have surpassed 5 million U.S. downloads within 22 days of launch.
Around 85% of those apps were games, including titles such as Fortnite and Pokémon GO. Sensor Tower identified only a small number of non-gaming applications in that group, including Disney+, HBO Max and Threads.
That comparison makes Muse’s early download performance notable, but it does not establish a ranking of the world’s fastest-growing apps.
Downloads also cannot show whether people actively use the service after installation or whether they eventually become paying customers.
Third-Party Access Creates Challenges
Muse’s ability to perform actions on external websites has already created friction.
Amazon blocked Muse from accessing its retail website in September. Bloomberg reported that Amazon prohibits other companies from deploying automated tools to shop on its platform and had asked Meta to remove the agent before blocking its access.
The situation illustrates one of the broader challenges facing AI agents. An agent may be technically capable of navigating a website, but that does not automatically mean the website operator will permit automated access.
As more AI systems attempt to make purchases, book services or complete forms, agreements between AI providers and third-party platforms could become increasingly important.
Muse Has a Paid Tier
Meta offers Muse as a free application while also developing paid options for heavier users.
Reuters reported that Meta planned pricing of approximately $20 per month for some services, with a higher tier around $100 for heavier users. These figures should be treated as reported pricing plans rather than assuming that every Muse user will pay those amounts.
The commercial model could become more significant if Meta can convert some of its early users into regular subscribers.
Competition in AI Agents Is Growing
Meta is not developing consumer AI agents in isolation.
Other major technology companies are also working on systems that can perform tasks rather than simply generate text. OpenAI has introduced its own agent-related products, while other companies are exploring ways to connect AI systems with websites, software and online services.
This means Muse’s early download performance is only one part of a much larger shift toward agent-based computing.
What Comes Next for Muse AI?
The 5 million-download milestone gives Meta evidence of strong initial interest, but the longer-term picture remains unclear.
The key questions will involve retention, reliability, paid subscriptions and access to third-party services. Muse will need to turn downloads into continued usage while ensuring that users are comfortable allowing an AI agent to interact with personal information and online accounts.
The Amazon restriction also demonstrates that the development of agentic AI depends partly on cooperation from other platforms.
FAQs
What is Muse AI?

No. Muse is currently available in the United States and Canada.
Has Muse reached 5 million downloads faster than ChatGPT?
According to Sensor Tower’s estimates, yes. Muse reached the milestone in 22 days compared with 56 days for ChatGPT. However, differences in platform availability and launch conditions make the comparison imperfect.

Muse is designed to assist with shopping, but access depends on individual platforms. Amazon has blocked Muse from its retail site.
Conclusion
Muse AI has achieved an estimated 5 million U.S. downloads in just 22 days, giving Meta a strong start for its personal AI agent.
The milestone is notable, but download estimates should not be confused with active users, retention or commercial success. Muse has benefited from strong app-store visibility and substantial promotion from Meta, while its ability to interact with external platforms has already encountered restrictions.
The next stage for Muse will depend on whether Meta can maintain user engagement, expand the agent’s capabilities and build a sustainable business around AI-powered task automation.
