Key Notes
- Sensor Tower estimates show growing adoption of Muse alongside a decline in new US downloads for ChatGPT, with different measurement periods requiring care.
- Early retention figures suggest that strong initial interest does not automatically translate into a lasting advantage over established assistants.
- Meta is expanding Muse into connected business workflows, making dependable task execution and clear user permissions central to its appeal.
Meta’s Muse has passed 10.9 million downloads since its September 8 launch, giving Mark Zuckerberg a growing foothold in the market for personal AI agents. Sensor Tower estimates, reported by Yahoo Finance on October 20, put more than 10.2 million of those downloads in the United States.
ChatGPT’s US downloads fell 25% over the latest 30 days compared with the preceding 30 days. Muse also reached an estimated 2.5 million daily active users on October 16. Those figures point to momentum for Meta, while measuring different aspects of the two products’ performance.
The AI Race Moves Beyond the Chat Box
Muse’s appeal rests on a different promise from simply producing a useful answer. In its launch announcement, Meta described an assistant that can browse websites, complete forms and keep working after someone closes the app. People communicate with it through a dedicated app or WhatsApp, while a separate cloud computer holds the agent and its connected data.
That design makes the product a test of delegation: will someone trust an assistant to advance a task between conversations? Meta says sensitive actions, including sending an email or making a purchase, require approval. Users can choose connected services and change the access they grant, rather than handing over unrestricted control.
We examined those practical boundaries in our coverage of Muse shopping. They matter because a successful demonstration and a dependable daily assistant are different achievements. An agent has to get the details right repeatedly, especially when a mistake affects a booking, a payment or another person.
Downloads Are an Opening, Retention Is the Test
The comparison with ChatGPT needs care. Cumulative installations since a product launch and a month-on-month change in US downloads are not equivalent measures of audience size. A slower flow of installs does not establish that existing users have stopped using ChatGPT, canceled subscriptions or moved to Muse.
Nor do downloads identify how much useful work an agent completes. Someone can try both services, keep both installed and use each for a different purpose. The commercially important question is whether repeated use becomes a habit strong enough to support a paid plan.
Earlier Sensor Tower figures published by Yahoo Finance on October 12 showed Muse bringing back 73% of new users the following day, nearly twice ChatGPT’s rate. But that early advantage weakened: ChatGPT overtook Muse’s retention between days eight and nine. The initial return visit and the lasting habit can tell different stories.
Meta Is Building More Reasons to Come Back
Meta’s business expansion shows how it wants to make Muse part of recurring work. The company added connections to services including Shopify, Slack, Stripe and QuickBooks, alongside Facebook Pages, Instagram professional analytics and Meta advertising accounts. Its pitch is that an assistant becomes more useful when it can work with the tools and records a business already uses.
That could give Muse a broader role than an occasional consumer experiment. It also raises the standard for reliability: remembering a preference is useful, but preparing customer communications or examining business records requires accuracy and clear permissions. Meta says publishing, sending and spending remain subject to approval.
The competitive stakes extend beyond this month’s app charts. Our analysis of Muse Wonder explored Meta’s position against other leading model developers. This download milestone tests a separate part of that strategy: whether people choose the product built around the technology. Model rankings alone cannot answer that question.
OpenAI’s Dots agents put the same broader contest into focus: assistants are competing to become the place where people delegate ongoing work. For Muse, the next persuasive evidence will be sustained usage, dependable task completion and paying customers. Its launch has earned attention; keeping that attention will determine how much it changes the AI race.
