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, in the US, for people 18 and over.
Here is what it handles, what it costs, and the four limits that decide whether it fits your week.
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. 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 so far are Gmail, Google Calendar, Google Workspace, 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.
The browser fallback is broad and also the most fragile of the three, because it breaks whenever the site changes.
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. At $100, Maximum is priced above every mainstream chatbot subscription.
The four limits that matter
It is US-only and adults-only.
Muse is US-only and 18-plus at launch, and it runs on one person's own accounts. Past mail and calendar, Meta's published connector list is consumer services, dining, music, tickets and fitness, with no CRM, project tracker, helpdesk or shared inbox on it. Carly connects the work systems and reaches thousands of apps.
It is a personal stack, not a working one. Beyond mail and calendar, the connectors are restaurants, playlists, tickets and workouts. The deal that needs logging, the invoice that needs chasing and the mailbox your team shares are not on the list.
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 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. Meta shipped on schedule.
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, all on personal accounts, in the US.
It is the wrong tool if the tasks that eat your day arrive at a work address, involve a client, or need to land in a system a colleague also opens.
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.
Where can I use Muse? In the Muse app on iOS and Android, on the web at muse.ai, and in WhatsApp chats. Meta says support for its AI glasses is coming.
Is Muse available outside the US? Not at launch. Meta says more countries will be added over time.
What apps does Muse connect to? Named connectors include Gmail, Google Calendar, Google Workspace, Ticketmaster, OpenTable, Spotify, Apple Health, Peloton, Plaid and Function Health, plus Facebook and Instagram. 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. Meta’s own testers still reported data-handling problems during the week of launch, so treat the permissions you grant as a decision worth revisiting.
Can Muse do work tasks? It connects Gmail, Google Calendar and Google Workspace, so basic personal work email is in reach. Business systems like CRM, helpdesk, project tracking and invoicing are not on Meta’s connector list at launch.

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."
