Meta Muse Explained: The No. 1 AI Agent App — Features, Pricing, and Whether You Should Trust It
Within a week of its September 8 launch, Meta’s Muse became the top free app on Apple’s U.S. App Store. Unlike a chatbot, Muse acts for you — buying groceries, sending emails, booking appointments, even calling customer service. It’s also the most controversial consumer AI product of the month. Here’s what you need to know before giving it access to your life.

What Muse Actually Does
Muse is a personal AI agent that completes tasks on your behalf. Meta says it can read and send email, book travel, fill in web forms, negotiate for you, and complete purchases. Early users have reported using it to cancel subscriptions, negotiate bills, process product returns, and even deal with parking tickets. It can place outbound calls to businesses and keep working in the background while you continue a conversation.
Muse runs on iOS and Android apps, on the web at muse.ai, and inside WhatsApp. It’s powered by Meta’s Muse Spark model family, whose latest version (1.3) is designed to finish tasks with fewer steps and tokens.
Pricing and Availability
| Plan | Price | What you get |
|---|---|---|
| Free | $0 | Up to 100 million tokens per week |
| Power | $20/month | Higher usage limits |
| Maximum | $100/month | Highest usage limits |
Muse is currently available only in the United States, for adults 18+. Meta says more countries will follow but hasn’t given dates, including for Europe.
Muse Charm and New Features From Connect
At Meta Connect this week, the company announced Muse Charm, a palm-sized device about the size of an AirPods case with a roughly 2-inch touchscreen, a microphone, and built-in 5G — deliberately without a camera. It’s meant to let you use Muse without taking out your phone. Charm ships in December 2026; Meta hasn’t announced a price. Muse is also coming to Meta’s smart glasses in the coming months, and a Muse Realtime Avatar feature enables live conversations with an AI avatar.
The Security Flaw
Security researcher Patrick Wardle found a zero-day vulnerability in how Muse handles authentication: another application or terminal command could potentially access the token used to sign in to a user’s Muse account. With that token, an attacker could piggyback on the agent’s broad permissions instead of writing their own malware.
There’s no evidence that Muse users have been broadly hacked. But the finding shows the core problem with powerful agents: the more access you give one, the more valuable it becomes to an attacker. Meta says passwords and payment details are kept in a secure credential store that Muse itself can’t read, and it has promised an even stricter setup where “even Meta” can’t access what’s in your agent.
Why Amazon Blocked It
Amazon has blocked Muse from shopping on Amazon.com. Users now see a message saying continued access by an unauthorized AI agent violates Amazon’s Conditions of Use. Amazon says it never authorized the integration, that Muse doesn’t identify itself as an agent, and that it appears to capture and store customer credentials — which Meta disputes.
Critics point out that Amazon runs its own shopping agents — Alexa for Shopping and Buy for Me — and that this mirrors its ongoing legal fight with Perplexity over the Comet browser agent. In practice, the dispute shows that agentic shopping will depend on which sites agree to let agents in. Muse purchases elsewhere go through Link by Stripe, which adds buyer protections.
Pros and Cons
Pros
Does real tasks, not just answers. Handles annoying chores like calls and cancellations. Generous free tier. Works in apps people already use, like WhatsApp.
Cons
Needs deep access to email, accounts, and payments. A disclosed zero-day. Blocked by Amazon. U.S.-only for now. Meta’s privacy track record makes some users wary.
Should You Use It?
- Try it for low-risk chores first: research, drafting emails you review, booking with confirmation.
- Be careful with financial access: use a separate card with a low limit if you let it make purchases.
- Review permissions: connect only the accounts it needs, and revoke access you’re not using.
- Keep the app updated, so you get security fixes as soon as Meta ships them.
FAQ
Is Meta Muse free?
Yes, there’s a free tier with a weekly usage cap. Paid plans cost $20 or $100 per month.
Can I use Muse outside the U.S.?
Not yet. It’s U.S.-only for adults, with other countries promised later.
Can Muse shop on Amazon?
Not currently. Amazon has blocked it, though it can still buy from other retailers.

Muse is the clearest sign yet that AI agents are going mainstream — it does things people actually want done. But it asks for a lot of trust at a time when its security and its relationships with major retailers are still being worked out. Start small, limit what it can touch, and expand only when it proves itself.
