Muse is Meta's personal AI agent, launched in the US on September 8, 2026 and in Canada about ten days later. You message it like a person through the iPhone or Android app, muse.ai, WhatsApp or the Mac app, and it does the work in its own persistent cloud computer with a full browser. It keeps working after you close the app and asks for approval before it sends a message, buys something or shares data.

What is Meta Muse actually good at?

Tedious, multi-step errands that get you money back or save hours: chasing airline delay compensation, cancelling forgotten subscriptions, data-broker opt-outs, watching booked travel for price drops, re-shopping insurance and waiting on hold. Reported results include a $250 Delta credit in five minutes, 90 data-broker opt-outs, $600 saved on travel and $3,500 a year on auto insurance.

Does Meta Muse work on iPhone and Windows?

Yes, almost everything does, because tasks run in Muse's cloud VM rather than on your device. Use the iPhone app ('Muse from Meta' on the App Store), WhatsApp, or muse.ai in a browser on the PC. A native Windows app was announced by Microsoft on October 7, 2026 with no release date. Avoid Microsoft Store listings that use the Muse name; as of October 23, 2026 none of them is Meta's.

How much does Meta Muse cost?

There is a free tier with a weekly allowance of roughly 100 million tokens, Power at $20 a month with 500 million Muse tokens a week, and Maximum at $100 a month with 3 billion. Meta does not say how many tokens a typical task uses; the app shows a meter. Meta makes money from a small fee on transactions rather than ads.

Is Meta Muse safe to use?

It is reasonably safe with approvals left on, but it has failed when acting unsupervised: on September 28, 2026 it accepted a low Marketplace offer and shared a user's home address without telling him. A Mac app zero-day disclosed on September 22 was patched. Keep anything that sends messages, shares personal information or spends money on 'allow once', connect one service at a time, and start email read-only.

Meta Muse — What It's Actually Good For

What Muse actually is #

The thing that makes Muse different from ChatGPT-style apps isn't the model. It's that every user gets a computer of their own in Meta's cloud, and Muse is allowed to keep using it while you're gone.

Figure 1 · The pieces Meta announced on Sep 8, 2026, and how a task moves through them

Piece	What it means for you
Muse Secure VM	A persistent, isolated Linux computer in the cloud with a full browser. You can watch Muse click through sites and take over at any point.
Sentinel agent	A separate program on the same VM that has to approve anything Muse sends to the internet, and asks you when needed.
Vault + Link by Stripe	Muse uses your logins but can't read them. At checkout it gets a one-time card number, and eligible purchases carry Link's buyer protections, a first for agents. 1Password and Shop Pay support is coming.
Approvals + audit	Before sending email, buying or sharing data it asks: allow once, always allow, or deny. A complete log shows what it did and what it plans to do.
Long-running tasks	It keeps working in the background and comes back when something changes or it needs a yes. This is the main difference from chat apps.
Memory	It remembers details you mentioned once (a friend's allergies, your preferred airline) and makes suggestions unprompted. You can tell it to “forget.”
Mac app · Sep 17	A direct DMG download, not from the App Store. It reads Messages, Calendar, Notes and files, and since Connect (Sep 24) it has computer use, so it can drive any app on the Mac.
Model	Muse Spark. The larger Muse Wonder line (Oct 12) goes to subscribers first.

Ten jobs it does well — with receipts #

These are the cases where people reported a measurable win. Each card ends with a prompt you can paste in as-is. Fill in the brackets.

Figure 2 · Individual results reported by users and reviewers, Sep–Oct 2026 · not averages

01 · Money back$250 in 5 min

Flight delay compensation

After a 7-hour delay, Muse filed the claim and got a $250 Delta credit. It also rebooked onto preferred airlines and answered the support email.

My flight [#] on [date] was delayed [X hrs]. Check if I qualify for compensation, a refund or a credit, prepare the claim for my review, and find alternatives on [airlines]. Ask before submitting or rebooking.

02 · Time backHours of hold

Waiting on hold for you

Muse called Southwest, waited on hold, and called the user back when a human picked up. “You had the rep wait for you.” Calling is in beta and not on every account.

Call [company] about [issue], wait on hold, and call me at [number] when a person is on. Tell me upfront if calling isn't enabled.

03 · Money back$200+ saved

Subscription audit & cancellations

Several users had Muse find recurring charges and cancel services they'd forgotten about.

Review my statements for recurring subscriptions. List amount and renewal date, flag duplicates, and ask which to cancel.

04 · Privacy90 opt-outs

Data-broker removal

One user had Muse complete 90 data-broker opt-outs, a job most people give up on after about four sites.

Find data-broker sites listing my info and request removal. Show matches first, ask before sharing more personal data, and track submitted, confirmed and needs-follow-up.

05 · Money back$600 saved

Price-drop watch on booked travel

Muse keeps checking booked flights and hotels and alerts you when a lower rate is worth taking once change fees are counted.

Monitor my booked flights/hotels for price drops. Factor in change and cancel fees, alert me only on a real saving, and ask before changing anything.

06 · Money back$3,500/yr

Insurance re-shopping

A founder switched auto insurance through Muse. The key is comparing coverage line by line, not just price.

Compare my auto policy with quotes for equivalent coverage: premium, deductibles, limits, exclusions side by side. Ask before submitting my info, and never switch without approval.

07 · DiscoveryIG on steroids

Instagram-powered local discovery

Find bars or restaurants with a specific vibe, see the Reels, then check hours and reservations for a group.

Search Instagram for cocktail bars in [area] like [favorite]. For [N] people on [date]: show reels, check hours and reservation availability, and let me pick before booking.

08 · HomeReel → action

Saved recipes → groceries

Meta's own example: turn a saved recipe reel into a grocery list (Instacart connector), plan a menu, and remember guests' dietary restrictions before sending invites.

Turn my saved recipe reels from this month into a cookbook doc and a grocery list for [store]. Plan a dinner for 6 and account for [friend]'s allergy.

09 · PlanningPlans that work

Planning under constraints

CNN found it strong here: a day-by-day packing schedule in short sessions with time estimates and a first-night bag. The same pattern works for training and study plans.

I move on [date], still need to pack [rooms]. Daily schedule, sessions ≤ [N] min, least-needed items first, plus a first-night checklist.

10 · WorkInbox triage

“I'm underwater” triage

With email and calendar connected, Muse flags what needs a reply, writes first drafts, and offers to take items off your plate.

I'm underwater. What needs my attention across email, calendar and news? What can you take off my plate? Draft replies but don't send.

On iPhone and a Windows PC #

Most Muse coverage assumes a Mac. Good news if you don't have one: almost every use case above works fully on an iPhone plus a Windows PC, because the work happens in Muse's cloud VM, not on your device.

Surface	Status	Use it for
iPhone app	Available “Muse from Meta,” 18+, US & Canada	The main way in: start tasks, approve actions, get pinged when a background task needs a yes. Hold-and-call-back (beta) works here.
WhatsApp	Available	Nothing to install. Chat with Muse next to your other chats, on the phone or WhatsApp for Windows/Web.
muse.ai in the browser	Available	Long tasks on a big screen; watch or take over the cloud browser, e.g. for checkouts. It cannot see files or apps on the PC.
Native Windows app	Coming soon Announced Oct 7, no date	Should bring local file and app access, sandboxed by Microsoft Execution Containers (MXC).
Mac app	Mac only	—

What changes without a Mac

No local reach yet. On a Mac, Muse can read Messages, Calendar, Notes and local files and drive any app. Windows users get none of that until the native app ships. To work on a document, put it in a cloud connector (Dropbox, Box and Notion are supported; OneDrive isn't listed yet) or upload it in chat.
iMessage stays private. Muse only reaches iMessage through the Mac app, so iPhone + Windows users don't expose their text history at all.
Email and calendar go through Muse's own connectors, not Windows or the iPhone's apps. Check the list in settings for your provider, and start read-only.
Smaller attack surface. The September Mac zero-day doesn't apply. The exposure is the cloud VM and the connectors you choose.
Work PCs: Muse is for personal accounts. Don't connect corporate mailboxes; Intune/Entra controls for agents on Windows are announced but not shipped.

Watch out for fake “Muse” apps in the Microsoft Store. A listing called “Muse AI for personal AI agent” is a Llama-4 chat app with a “5 free conversations” paywall, and it is not Meta's. There are also GitHub wrappers and “MuseWork” lookalikes. Until Meta publishes an official Windows installer, use muse.ai in the browser.

Daily pattern

Start on the phone, review on the PC

Kick off or approve tasks on the iPhone, then read long results at muse.ai on the big screen. Everything in section 02 works this way today.

Muse for Small Business #

Launched Sep 29, 2026

Connect your Instagram professional analytics, Facebook Pages and Meta ad accounts, and Muse starts out knowing what you sell, how your brand sounds, and what customers keep asking.

Third-party connectors cover most of a one-person shop's stack, and custom connectors are supported. Nothing publishes, sends or spends without approval.

Where it falls down #

Every one of these is a reason to keep approvals on, not a reason to stay away.

Acting unsupervised can go badly. Sep 28A user let Muse sell a keyboard on Marketplace. It accepted a low offer and shared his home address without telling him. Don't give it “always allow” for messaging strangers or selling.
Mac zero-day, since patched. Sep 22Patrick Wardle showed that malware already on a Mac could hijack the Muse app's auth material, and with it Muse's broad permissions, without any special macOS permissions. Meta patched it, but Messages, Notes and computer use is a lot of reach for one app.
Stale facts.CNN got two date-night suggestions for places that had been closed for years. Treat recommendations from its memory as leads to check.
Walled gardens.Amazon blocks Muse outright, and Target blocked its automated checkout clicks. It shops best at connector partners: Shopify stores (Shop Pay), Walmart, Best Buy, Sephora, Ulta, Wayfair, Gap, Instacart and PayPal merchants. Expedia is coming.
Advertised ≠ delivered.The Ideas tab said it could haggle with Marketplace sellers; in CNN's test it only vetted listings and drafted the message.
Meta can still reach your VMuntil Muse Confidential VM (user-held key) ships “later this year.” Conversations aren't shared with ad systems, and you can opt out of training.

Cost and availability #

Figure 3 · Free figure is Zuckerberg's estimate; a card may be required at signup

Meta doesn't say how many tokens a typical task uses; the app shows a meter with what's left. The business model is a small fee on transactions, not ads. Muse is 18+, passed 2.5 million downloads in its first 13 days, and hit #1 on the US App Store.

Usefulness scorecard #

Scored on payoff, risk with approvals on, and how much of the job it actually finishes.

Figure 4 · Desktop computer use is Mac-only today and not yet available on Windows

Category	Why
Money recovery	Refunds, credits, subscriptions, insurance, price drops. Clear payoff, low risk with approvals on, and exactly the chore people put off.
Bureaucratic grind	Opt-outs, forms, hold queues. Background persistence is the killer feature here.
Planning & goals	Strong at turning constraints into schedules, and it keeps adjusting them.
Instagram discovery	Something only Meta can do well. Check that places are still open.
Small-business ops	Native access to Meta ad and Page data is a real advantage. Output is drafts, and you decide.
Shopping	Good at partner stores, blocked at Amazon. Link protections help.
Selling / negotiating	The Marketplace incident shows what happens. Keep it to drafting.
Desktop computer use	Powerful on the Mac, but the zero-day history and the breadth of access argue for caution. Expect the same with the Windows app.

A safe setup, in this order #

Start with one low-stakes job and nothing connected, like a packing list or a price watch.
Connect one service at a time. Start email as read-only.
Choose allow once for anything that sends a message, shares personal info or spends money.
Read the activity log after each task, and disconnect services you stop using.
Opt out of model training if you want to, and use “forget” for sensitive details.
Install only “Muse from Meta” from the App Store on iPhone. On Windows, use muse.ai in the browser until Meta or Microsoft officially ship the native app.

Meta Muse, honestly.
