Carly vs Meta Muse: Which AI Agent Fits Your Work?
Meta Muse is Meta’s personal AI agent. Give it a goal and it opens a browser on its own cloud computer, fills in the forms and pays the bill inside your connected accounts. Carly is an AI assistant and agent builder that works inside your email, calendar and the apps your business runs on.
Both act instead of just answering. They are pointed at different parts of your life.
The quick answer: Muse if the problem is errands: the trip to book, the tickets to catch, the bill to argue down. Carly if the problem is your inboxes, your calendar and your clients, especially across more than one account, and you want work to start the moment an email lands. Free Zapier-style workflows; AI agents from $35/month.

What Muse is built for
Muse launched on September 8, 2026, and its examples are personal: book a trip, catch tickets, fill out a school permission slip, plan a training block. Each person’s agent runs on its own cloud machine, so it keeps working after you close the app. A separate monitoring agent called Sentinel stops for your approval before anything high-risk, and payments go through Link by Stripe with one-time card numbers.
On September 29, Muse for Small Business added Slack, QuickBooks, HighLevel, Shopify, Stripe, Asana and Zoom. Where no connector exists, Muse builds one from an API key you supply, or drives the website in a browser.
What Carly is built for
Carly’s day starts in your inbox. Connect every Google and Microsoft account you have and it triages, drafts replies in your voice and sends them from the right address. It finds times and moves meetings across all of your calendars, with booking pages for the people who need to grab a slot. The deal moves in HubSpot, the task lands in Asana, the note lands in the Carly CRM.
Then come workflows. An email from a key client, a form submission, a new booking, a Monday at 8am: each can start a run with an AI step in the middle. The agents you build each get their own email address, so clients and colleagues can CC them like a person.
The inbox gap
This is where the two split hardest. Muse’s Gmail and Outlook connectors hold one account each, and Meta has named no shared mailbox connector. If you run a business address, a personal address and a client’s Microsoft 365, Muse sees one of each provider at most.
Carly holds all of them. Michael runs a three-person bookkeeping firm with his own Workspace domain, a Gmail he uses for older clients, and a seat in one client’s Outlook. When that client sends a receipt at 10pm, Carly files it, logs it in QuickBooks and drafts the reply from the client-side address. Muse would never have seen the email.
Who starts the work
Muse acts when you ask, then advances the plan you set. Sentinel stopping for approval is the right design for spending money, and it also makes you the bottleneck: the agent moves as fast as you check your phone.
Carly starts on the event. The email arrives, the meeting gets booked, the lead changes stage, and the workflow runs. Each agent either sends on its own or drafts for your approval, which you set once per agent rather than per action.
Privacy
WIRED reported that Muse users are opted in to AI training by default and cannot switch memory off, and Meta is still disputing an Inc columnist’s report that Muse synced his iMessages after he declined that access. Carly does not train on customer data, and it reaches only the accounts and tools you connect.

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."
