Less than two weeks after launch, Meta’s personal AI agent Muse climbed to first place in the U.S. App Store, overtaking ChatGPT, Claude and Grok. We break down what exactly happened and why it matters for the AI assistant market.
What Is Meta Muse
Muse is a personal AI agent from Meta, launched on September 8, 2026. Unlike ordinary chatbots that only answer questions, Muse is designed to perform tasks on behalf of the user: send emails, book travel, make purchases — after connecting to the relevant apps and personal accounts. The service runs on the Muse Spark family of models and is available in the U.S. on iOS, Android, WhatsApp and through a web version.
Muse is free for basic use, with paid plans priced at $20 and $100 per month.
How Fast Downloads Are Growing

On September 18, 10 days after launch, Muse became the No. 1 app in the free category of the U.S. iOS App Store, overtaking ChatGPT — according to analytics company Sensor Tower, the app recorded more than 730,000 downloads in roughly its first five days. As of Monday, September 21, total downloads had exceeded 2.5 million.
Over the same 13-day period after launch, Muse also surpassed Claude (400,000) and Grok (200,000) in cumulative downloads. ChatGPT received 3.1 million downloads over a comparable period — Sensor Tower notes that the apps launched on iOS and Google Play at different times, so a direct comparison of the figures is not entirely precise.
Why Amazon Restricted Muse Access

Amazon blocked the Muse bot from accessing its website, citing privacy and security concerns about third-party AI agents acting on behalf of shoppers. This is more of a warning about the broader risks of autonomous agents operating with access to users’ personal accounts than a dispute specifically between the two companies.
Market Reaction and Meta’s Next Plans

JPMorgan upgraded Meta shares from “Hold” to “Buy,” raising its price target from $640 to $820. Meta shares rose more than 8% to their highest level since February. On September 17, Mark Zuckerberg announced a Mac version of Muse.
Analysts warn against drawing premature conclusions: some AI apps, including OpenAI’s Sora and Meta’s own Vibes video feature, also showed sharp download spikes immediately after launch that later faded. Whether Muse can retain its audience over the long term remains to be seen.
