Meta's Muse Is Beating ChatGPT on Downloads. It Won't Say How Much You Can Use It.
Meta's Muse AI agent outpaces ChatGPT's early downloads and daily users, per third-party data. Usage caps stay undisclosed on all three pricing tiers.
Published: September 22, 2026 Impact: High. Affects anyone considering an autonomous AI agent that can spend money, send messages, or browse on their behalf.
What Happened (This Week)
Meta launched Muse, a "personal AI agent," on September 8, 2026, US-only on iOS, Android, web, and WhatsApp. It runs on a virtual machine, sending emails, booking travel, filling forms, buying things via one-time-use Stripe cards.
Three tiers exist: free, $20/month Power, $100/month Maximum. None of Meta's materials say how many tasks any of them allows.
In its first 12 days, Muse logged 1.8 million US/Canada iOS downloads to ChatGPT's 1.3 million, and 642,000 daily US users to ChatGPT's 231,000, per Apptopia, cited by TechCrunch, not Meta.
What This Means
Muse runs on a model Meta calls "Muse Spark," its "most capable model to date, built for real-world agentic work." Separately, Sentinel asks permission "when needed" for "sensitive actions like sending an email or making a purchase."
I read Meta's own wording twice, looking for what triggers "when needed." It isn't there: no threshold, no example of what needs approval. An agent that buys things for you is only as trustworthy as that rule.
Caveat: Sensor Tower clocked a slower two-day pace: 83,000 US iOS downloads, with ChatGPT ahead. Appfigures puts Muse at #1 overall, past 1 million downloads. None of these figures come from Meta.
What This Costs You
Muse can message, fill forms, and spend money without you doing each step, and none of its three tiers discloses what a subscription buys. A card is reportedly required even for the free tier (DataCamp, unconfirmed).
Verdict: an agent that can spend your money, sold at three prices with none disclosing what you get, isn't a problem you can shop around. It's one Meta hasn't fixed yet.
On August 26, 2026, a federal judge approved Meta's settlement with 47 states, DC, and other territories, over claims it engineered Facebook and Instagram to maximize teen engagement while concealing harms. The $18 billion, ten-year deal isn't guaranteed: 70% fixed, 30% contingent on rivals like TikTok and YouTube adopting comparable safety measures. Meta separately settled Texas for $1 billion; neither involves Muse: the 13-day gap is timing, not conduct.
Consumer Protection Q&A
Q: What can Muse do without asking first? A: Not published: Sentinel "asks when needed," undefined.
Q: How many tasks does each tier include? A: None published: Free, Power ($20), or Maximum ($100).
Q: Do I need a card for the free tier? A: Reportedly yes, per DataCamp, not confirmed elsewhere.
Q: Is Muse really beating ChatGPT? A: Yes, on Apptopia's 12-day numbers, but Sensor Tower's two-day snapshot showed ChatGPT faster. Different windows.
Q: Is Muse tied to the $18B settlement? A: Not in substance: that deal covers Facebook and Instagram, not Muse. The 13-day gap is timing, not allegation.
What Happens Next
30 days: whether Meta publishes a usage cap. 90 days: whether Sentinel's rules get detailed enough to predict. 6-12 months: whether Muse's lead holds once novelty fades and Meta's own numbers, once released, replace third-party estimates.
What to Do Next
- Budget assuming no tier has a published ceiling; track usage yourself, not by tier name.
- Before linking a card, check Sentinel's purchase authority and confirmation rules.
- If autonomous purchasing is the draw, ask what happens when Muse errs before trusting it with anything costly.
- Muse isn't yet on OneHuman's Compare Page. It'll be evaluated in the next scheduled update.
Bottom Line
Muse does something ChatGPT, Claude, and Gemini aren't doing: autonomous action with a payment method attached. What's missing is a number: how much $0, $20, or $100 buys. Launching undisclosed spending authority 13 days after an unrelated $18 billion settlement invites scrutiny regardless of intent.
