Meta Muse Explained: What It Does, Who Can Get It, and What It Costs

Meta launched a personal AI agent called Muse on September 8, 2026, and the pitch is not "a better chatbot." In Meta's words, "it doesn't just answer questions, it actually does the work." Muse gets its own computer in Meta's cloud, its own browser, and permission to act on your accounts: sending email, filling in forms, booking travel and buying things. Meta's own product FAQ puts it in the US and Canada for people 18 and over, there is a free tier with a usage cap, and the two paid plans cost $20 and $100 a month.

Key Takeaways

• It is in the US and Canada, and you have to be 18. Muse's product FAQ, read October 2, 2026: "Available today to people in the US and Canada who are 18 and over." Meta's launch post has not been updated and still says "rolling out in the US."
• No third country, and Meta says so directly. "We're working to bring Muse to more markets, and we're taking a measured approach in each one. We don't have additional timing to share now."
• You can use it inside WhatsApp, which is the detail that decides how many people meet it. Meta says talking to Muse "works just like messaging another person, in the Muse app or directly in WhatsApp."
• The free tier is capped, and the paid plans are priced. Meta: "Muse is available for free with a usage limit." Above it, on Meta's own help page: Power plan ($20/month), "500M Muse tokens per week", and Maximum plan ($100/month), "3B Muse tokens per week."
• It can spend money, through Link built by Stripe, using a one-time-use card so your real details stay hidden. Meta says Muse is the first AI agent covered by Link's purchase protections.
• Nothing it does reaches the internet unopposed. A separate Sentinel agent runs alongside it: "Nothing Muse does reaches the internet unless the Sentinel approves it."
• It keeps working when you close the app, and comes back "when something changes or when it needs approval, like before it sends an email or makes a purchase."
• Training is opt-out, not opt-in. Meta says "people can also opt out of their interactions being used to train Meta's AI models."
• Meta says it will still get things wrong: "Muse can and will still make mistakes."
• Full encryption is not here yet. Meta says Muse Confidential VM, where only you hold the key, arrives "later this year."

What Muse Actually Does

It carries out multi-step tasks on your behalf rather than telling you how to do them. Meta's examples are ordinary errands, not demos: selling a car for more than you would have got, lowering a bill, adjusting a training plan when your week changes, turning a recipe reel you saved on Instagram into a grocery list and remembering your friends' dietary restrictions before it sends the dinner invites.

The mechanics behind that are what separate it from a chatbot. Meta says Muse "can open a browser, fill out forms, and negotiate on their behalf," and that for longer jobs "Muse keeps working after people close the app, and comes back when something changes or when it needs approval." If you want the general version of this idea, our guide to what an AI agent actually is covers how the same pattern shows up in ChatGPT, Gemini and Claude.

The model underneath is Muse Spark, which Meta calls "Meta's most capable model to date, built for real-world agentic work."

Where You Can Get It

The US and Canada, if you are 18 or over. Meta's two surfaces do not say the same thing, and the newer one is the product's own. Muse's small-business FAQ, read October 2, 2026, answers the question directly: "Available today to people in the US and Canada who are 18 and over." Meta's September 8 launch post still reads "rolling out in the US" and has not been amended, so Canada and the age gate appear on the product site and nowhere else we could find.

One caveat Meta attaches itself, on the subscriptions page: "Muse and Muse subscriptions are in limited testing and aren't available in all locations yet," and "benefits and availability may vary by region and account."

What It Costs

There is a free tier with a cap, and two paid plans at $20 and $100 a month. The numbers are on Meta's own help page, About Muse subscriptions, which the product FAQ links to and which the launch post does not.

Meta's framing of the free tier is the part that matters most: "Muse is available for free with a usage limit. If you reach your free usage limit and want more usage, you can upgrade to a paid subscription or wait until your free usage limit refreshes." So the free tier is not time-limited, it is volume-limited, and hitting the ceiling costs you a wait rather than access.

Two things Meta does not publish. It gives no conversion from "Muse tokens" to anything a person can picture -- no messages, no tasks, no hours -- so the step from 500M to 3B tells you the ratio and nothing about whether either is enough for you. And it names no currency, though the prices are written with a dollar sign on a US and Canada product.

Billing is month to month: "Muse subscription renews automatically each month unless you cancel your subscription. You're charged on the same date each month as your original purchase date." You must be "18 or the age of majority in your country to subscribe."

What you can act on today: start free. The cap resets, so the cost of finding out whether Muse is useful to you is a wait rather than $20. If you already pay for ChatGPT Plus or Google AI Pro, note that Power is the same $20 and Maximum is the same $100 as ChatGPT's Plus and Pro entry prices, which makes this a straight substitution question rather than an extra subscription.

The Money and Email Question

This is the part worth reading slowly, because Muse is asking for more access than a chatbot ever has. Meta's own descriptions of the limits are specific, which is a good sign, and they are worth knowing before you connect anything.

Two of those rows deserve emphasis because they cut the other way. Training is opt-out. Meta offers the control but does not say it is off by default, so if you care, go and find that setting rather than assuming. And end-to-end encryption is a promise, not a feature: until Muse Confidential VM ships, the VM holding your data and conversations is Meta's to reach.

How Much Should You Trust It

Meta's own answer is the honest one: "Muse can and will still make mistakes, but we expect they'll be much less frequent and cause much less damage due to the safety systems we've built in." That is a fair description of where agents are in September 2026, and it is more candid than most launch posts manage.

The structural protection is the Sentinel: a separate agent running on the same machine, "kept apart from Muse at the system level," that every outbound action has to pass and that Muse cannot override. Credentials go into secure storage rather than to the agent, "including passwords a person types into the browser themselves."

Meta has also put a price on finding holes in it. Its security post opens the Muse bug bounty to anyone and "awards up to $300,000 for valid reports, including up to $130,000 for successful prompt injection attempts that affect one user." A six-figure bounty specifically for prompt injection is a company telling you which attack it expects, and prompt injection is exactly the risk that comes with letting software browse the web on your behalf. It is the same warning OpenAI attaches to ChatGPT's Computer History.

Should You Use It

Try it if you are in the US or Canada, you are 18 or over, you already use WhatsApp, and there is a specific errand you keep putting off. The free tier costs nothing and the WhatsApp route means no new app. Start with something reversible.

Connect the minimum. Give it read access before send access on email, and add services one at a time. Meta lets you set this per app, so use that rather than accepting a default.

Turn off training first if that matters to you. Meta says the control exists; it does not say it is on your side by default.

Wait if you want the encryption. Muse Confidential VM is the version where Meta genuinely cannot see your data, and it is not out. "Later this year" is a save-the-date.

Do not pay on day one. The free tier is volume-capped, not time-capped, so the limit refreshes and you lose nothing by waiting. Meta publishes no translation from "Muse tokens" into messages or tasks, so until you have hit the free ceiling yourself you have no way to judge whether $20 buys you a lot or a little.

Ignore it entirely if you are outside the US and Canada. Meta names no third country and no timeline: "We don't have additional timing to share now."

Sources, all re-read on October 2, 2026: Meta's announcement, Introducing Muse: The World's First Personal AI Agent Built for Everyone, published September 8, 2026; its security and safety post; the product site muse.ai and its small-business FAQ, which is the only Meta surface that names Canada and the age gate; and Meta's help page About Muse subscriptions, which is where the $20 and $100 prices are published. Every quotation on this page comes from one of those five.

Corrections and Updates

October 2, 2026: this page said Meta had not priced the paid plans, and Meta had priced them within three days of launch. The page said "Meta has published one sentence about money and no numbers" and told readers that any price they saw elsewhere was unconfirmed. Meta's help page About Muse subscriptions publishes Power plan ($20/month), "500M Muse tokens per week" and Maximum plan ($100/month), "3B Muse tokens per week", and the earliest archived copy carrying those figures is dated September 11, 2026 -- two days after this page was published. The original claim rested on muse.ai not loading on September 9; that was a failed read, not a Meta silence, and this page should not have turned it into one.

October 2, 2026: this page said Muse was US-only, and Meta's product FAQ says the US and Canada. Muse's small-business FAQ states "Available today to people in the US and Canada who are 18 and over." The 18 and over gate was not on this page at all. Meta's September 8 launch post still reads "rolling out in the US" and has not been amended, so the two surfaces disagree and the product site is the newer one; both readings are now published above.

October 2, 2026: muse.ai reads normally now. The page previously recorded that it "did not return a readable page on September 9, 2026." Re-checked today it answers 200 at 107,540 bytes, and it names a Mac app that the launch post does not mention, plus "1Password integration coming soon." A muse.ai/pricing URL returns 401, which says only that there is no such page to read.
