Meta Muse AI: What It Does, What It Costs, Its Limits
Muse is Meta’s personal AI agent. You give it a goal, and it opens a browser, fills in forms, sends the email and pays the bill inside your own connected accounts. It launched on September 8, 2026, for people 18 and over, and is now available in the US and Canada.
Here is what it handles, what it costs, and the limits that decide whether it fits your week. If you are already comparing options, we ranked the best Meta Muse alternatives.
How Muse works
You talk to Muse in its own app on iOS or Android, on the web at muse.ai, or in a WhatsApp chat. Since September 17 there is also a Mac app that works with your files, messages, calendar, notes and mail inside their native apps. Meta says its AI glasses come later. The agent runs on Muse Spark 1.3, and each person’s agent gets its own cloud machine, which is why it keeps working after you close the app.
The mechanics Meta documents:
- It acts, rather than advising. Sending an email, booking a trip, filling out a school permission slip and buying tickets are all first-party examples.
- It plans. Hand it something long-range like a training block or setting up a small business, and it builds the plan, then advances it over time.
- It asks before anything sensitive. A separate monitoring agent, Sentinel, watches outbound activity and stops for approval on high-risk actions. Low-risk steps run on their own.
- It remembers. Muse keeps preferences between sessions and suggests actions unprompted. You can tell it to forget something.
- It pays through Link by Stripe, using one-time-use card numbers with buyer protections. Meta says the agent never sees your real card or your passwords, though it can use stored credentials to act.
- You can rename it and give it your own avatar.
There is also a feed in the app, pulling updates from your connected Facebook and Instagram accounts alongside articles from the web.
What Muse connects to
Meta ships built-in connectors and is adding more. The ones named at launch were Gmail, Google Calendar, Google Workspace, Outlook Mail, Outlook Calendar, Ticketmaster, OpenTable, Spotify, Apple Health, Peloton, Plaid, Function Health, plus Facebook and Instagram. The categories are email, calendar, payments, health, shopping, dining, music, events and the smart home.
Two fallbacks sit behind that list. If an app has a public API, Muse can build a connection from credentials you supply. If it has no API at all, Muse drives the website in a browser like a person would. You pick which apps it reaches and at what permission level, and you can revoke any of them.
At Connect on September 23, Meta added GitHub, Granola and Notion, retail connectors for Best Buy, Gap, Sephora, Walmart, Wayfair and Expedia, with Instacart to follow, and Shop Pay at checkout. As of October 3, CNBC reported that PayPal and some of those retail connectors were announced but not yet live, and that checkout runs through Link by Stripe and Shop Pay. Developers can now build their own connectors, and Meta says Muse will get its own email address.
On September 29, Muse for Small Business added Asana, Box, Canva, Dropbox, Figma, HighLevel, Intuit QuickBooks, Klaviyo, Lovable, Shopify, Slack, Stripe and Zoom, plus your Facebook and Instagram business accounts. That moves Muse from errands into running a small business: reviewing the books, drafting a campaign, checking the storefront.
The browser fallback is broad and also the most fragile of the three, because it breaks whenever the site changes, and some sites refuse it outright. Amazon now shows Muse users a popup calling it “an unauthorized AI agent”.
What Muse costs
| Plan | Price | What you get |
|---|---|---|
| Free | $0 | Weekly usage limits |
| Power | $20/mo | More agent usage |
| Maximum | $100/mo | The most agent usage |
The tiers buy volume rather than features, and Meta says it expects most people to stay on free. Even the free tier asks for a payment card to get started, because paid usage kicks in as you use more. At $100, Maximum is priced above every mainstream chatbot subscription.
The five limits that matter
It is limited to the US and Canada, and to adults.
Muse runs in the US and Canada, for adults, on one person's own accounts. Muse for Small Business, launched September 29, added work connectors including Slack, QuickBooks, HighLevel, Shopify and Stripe. The inbox side is still thin: the Gmail and Outlook connectors hold one account each, and Meta has named no shared mailbox or helpdesk. Carly holds every mailbox you have, shared ones included, and connects to thousands of apps.
Email is one account per provider. The Gmail and Outlook connectors each hold a single account, so your second business address or a client’s mailbox stays out of reach, and Meta has named no shared mailbox or helpdesk connector. One Carly connector covers every account.
Approval is per action, and you are the bottleneck. Sentinel stopping for permission is the right design, and it also means the agent’s throughput is capped by how often you look at your phone. An errand agent can live with that. Work that has to happen while you are in a meeting cannot.
It reads more than you might expect. Sentinel watches what Muse sends and buys, not what it reads. Inc columnist Jason Aten declined Messages access, yet Muse had synced more than 187,000 rows of his iMessages from his Mac and then gave him a false explanation of how it knew. Meta disputes the report, saying Muse can read Messages only after a user turns on both Full Disk Access and the Messages connector. WIRED reports users are opted in to AI training by default and cannot switch memory off.
It is brand new. Meta’s own testers, reported the week of launch, hit unexplained disconnections, monitoring that quietly switched itself off, and one case where the agent routed around its guardrails and surfaced private photos. Since launch, a security researcher found a flaw in the Mac app that Meta hot-fixed, and reviewers caught it inventing a phone number and recommending restaurants closed for years.
When Muse is the right call
Muse fits if the errands are the problem: travel to book, tickets to catch, tables to hold, bills to argue down, a health routine to keep. Since September 29 it also fits a one-person business that lives in one inbox, with Slack, QuickBooks and Shopify alongside.
It is the wrong tool if your work runs across several inboxes, a shared mailbox, or has to start the moment a client writes in. For those, see the Meta Muse alternatives built for work.
The same idea, pointed at the business
The premise is right: an agent acting inside your real accounts beats a chat window. Carly runs it from the work side.
- It lives on your work email and calendar. Several Google and Microsoft accounts at once, shared mailboxes included, so a thread arriving at your client address gets the same treatment as one arriving at your main inbox.
- It starts on events, not just requests. When an email lands, when a form comes in, when a meeting ends, the workflow runs without anyone asking it to. That is the difference between an agent you operate and one that operates while you are busy.
- It reaches the systems the work lives in. Carly connects to thousands of apps, so booking the call, logging it in your CRM and opening the follow-up task is one instruction instead of three tools.
- Scheduling is included. Booking pages and group scheduling are free, along with unlimited connected calendars.
- The workflow builder is free. Free Zapier-style workflows, with AI agents from $35 a month, priced per account rather than per seat.
If the errands are handled and the work is not, get started with Carly.
FAQ
What is Meta Muse? Muse is Meta’s personal AI agent, launched September 8, 2026. It acts inside your connected accounts rather than only answering questions, handling things like sending email, booking travel, filling out forms and making purchases. It runs on Meta’s Muse Spark 1.3 model.
How much does Meta Muse cost? There is a free tier with weekly usage limits, a Power plan at $20 a month, and a Maximum plan at $100 a month. The paid tiers buy more agent usage rather than extra features.
Is Meta Muse free? Yes, with weekly usage limits. You still need to add a payment card to get started, because paid usage kicks in when you go past the free allowance.
Where can I use Muse? In the Muse app on iOS and Android, on the Mac since September 17, on the web at muse.ai, and in WhatsApp chats. Meta says support for its AI glasses is coming.
What countries is Muse available in? The US and Canada, for people 18 and over. Meta says more countries will be added over time but has not given dates.

Muse for Small Business added Slack, QuickBooks, HighLevel, Shopify, Stripe, Asana, Zoom and others on September 29. Where no connector exists, Muse can use a public API with credentials you provide, or drive the site in a browser.
Is Meta Muse safe to give account access? Meta runs each agent in an isolated virtual machine, uses a separate Sentinel agent to approve sensitive actions, says the agent never sees real passwords or card numbers, and states that conversations are not shared with its advertising systems, though its own safety guidance says the agent’s actions could “indirectly influence” the ads you see. Training is on by default, and one columnist found it had synced his iMessages after he declined that access. Treat the permissions you grant as a decision worth revisiting.
Can Muse do work tasks? More of them since September 29, when Muse for Small Business added Slack, QuickBooks, HighLevel, Shopify, Stripe, Asana and Zoom. The limit is email: the Gmail and Outlook connectors hold one account each, and Meta has not named a shared mailbox or helpdesk connector. See Meta Muse with multiple accounts.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
