Meta’s new artificial intelligence companion, Muse, surged past 10.2 million U.S. downloads within forty days of its launch, joining a rare tier of mobile releases while logging retention rates that outpace established rivals like ChatGPT.
Meta Pushes Muse Past 10 Million U.S. Downloads in Forty Days
The newly launched artificial intelligence agent Muse has crossed an adoption threshold. Developed by Meta, the application accumulated 10.9 million downloads since its September debut, with the vast majority—10.2 million installations—occurring inside the United States.
That velocity places the conversational assistant into an exclusive tier. According to data from market intelligence firm Sensor Tower, Muse became just the twelfth application in history to reach 10 million U.S. downloads within forty days of release since the firm began tracking mobile metrics in October 2015. The previous non-game application to clear that bar was Meta’s Threads, which achieved the milestone following its release in July 2023.
Most applications that reach this milestone so quickly are mobile games. The elite group includes titles such as Fortnite, PUBG Mobile, and Pokémon GO, alongside streaming service Disney+.
Meta Boosts Muse Growth Through Heavy Advertising Spend
Muse’s rapid ascension is not simply a product story. It reflects a distribution strategy that uses Meta’s existing ecosystem.
The company promotes the assistant across a family of social platforms that reaches 3.6 billion daily active users, creating a massive launch surface similar to the network effects that lifted Threads through its Instagram integration. Beyond organic cross-promotion, Meta backed the release with paid media.
Data shows that Muse accounted for 39% of Meta’s total U.S. advertising spend in October, an increase from 23% the previous month. Over that same window, the application climbed from 73rd to 21st place among U.S. brands ranked by advertising impressions.
Meta's, $META, Muse has surpassed 10.9 million downloads since its launch on Sept. 8, according to Sensor Tower. In contrast, ChatGPT downloads have declined by more than 25% over the last 30 days in the US
Retention Metrics Outpace Competing AI Assistants
While initial downloads capture public attention, user retention offers a measure of engagement. Here, Meta’s agent demonstrates an early advantage over competing conversational tools.
U.S. users are returning to the platform at higher rates than those observed for comparable artificial intelligence applications. Muse logged a 30% retention rate after seven days, which dipped to 23% after fourteen days. By comparison, rival services including ChatGPT, Claude, and Grok averaged 19% retention at the seven-day mark and 16% after two weeks.
Daily active users reached 2.5 million on October 16, representing a 15% increase compared to the previous week. The assistant also held the top spot on the U.S. App Store for nearly every day since its release, save for a brief interruption when streaming platform Kick edged ahead.
Geographic Limits Shape Global Comparison With ChatGPT
Comparing download figures across different artificial intelligence tools requires accounting for regional availability. While ChatGPT recorded roughly 15 million global downloads during its first forty days—surpassing Muse’s worldwide total—the two applications rolled out under different geographic constraints.
Muse remained restricted to the United States and Canada during its initial tracking period. ChatGPT enjoyed an international rollout from the outset, capturing users across markets including Brazil, Germany, and Japan, with Japanese users alone accounting for 25% of its global downloads during its first forty days.
| Application | U.S. Downloads (First 40 Days) | 7-Day Retention Rate | 14-Day Retention Rate |
|---|---|---|---|
| Muse | 10.2 million | 30% | 23% |
| ChatGPT | 3.7 million | 19% (average across peers) | 16% (average across peers) |
| Grok | 500,000 | 19% (average across peers) | 16% (average across peers) |
| Claude | 200,000 | 19% (average across peers) | 16% (average across peers) |
Privacy Concerns Emerge During Rapid Growth
Even as user acquisition numbers climb, the rapid deployment of autonomous AI agents has brought data protection challenges to the forefront. Security researchers recently discovered that shared user conversations could expose sensitive personal and business information, prompting Meta to suspend the sharing feature while investigating the flaw.
The incident points to operational hurdles facing developers of digital assistants designed to execute complex tasks on a user’s behalf. As competition intensifies among major technology firms, Muse faces the test of converting its early marketing-driven momentum into sustained, secure utility.
