Q · Short answer
What are Muse connectors?
Muse connectors link Muse, Meta’s AI agent, to the apps and services you already use, so it can work in them on your behalf — reading your calendar, finding an email, sending an invoice or changing your website. Built-in connectors are managed in the Muse app under Settings → Connectors; others are added by their address as custom connectors.
What a connector actually does
On its own, Muse only knows what you tell it in the chat. A connector opens a door into one specific service — your inbox, your documents, your payments, your website — so Muse can look things up there and, where the connector allows it, take action.
Each connector decides what Muse can do. Some only read: they let Muse find a receipt or summarize a thread. Others act: they send an invoice, publish a page or issue a refund. You see what a connector can access when you connect it, and that permissions screen is worth reading every time.
This is why the right connectors matter more than the model itself for everyday work. Asking “which customer emails still need a reply?” is only useful if Muse can actually see your email.
Built-in vs. custom connectors
There are two kinds of Muse connector, and they’re added differently:
- Built-in connectors appear in the Muse app under Settings → Connectors. You tap Connect, sign in to the service and approve access. Gmail, Google Calendar and Outlook were named at Muse’s launch on September 8, 2026, and Meta named many more — including Notion, Slack, Stripe and Shopify — on September 29.
- Custom connectors aren’t in the built-in list. You add them using an address their maker publishes, then sign in. AI Website Builder and Digital Marketing & SEO connect this way.
Built-in doesn’t automatically mean better — it means Meta lists it. Some of the most capable connectors are custom; they just take one extra step to add. See how to add a connector to Muse for both methods.
How many Muse connectors are there?
Meta doesn’t publish an official public list. As of early October 2026, public sources confirm about 41 built-in connectors as live, with more — including PayPal and Railway — announced as coming soon. Muse also supports custom connectors, so the real number of services it can reach is larger.
One connector stretches that further than any other: Zapier, which Zapier says lets Muse reach more than 9,000 apps and 40,000 actions once you authorize it.
We keep a list of every connector we’ve reviewed, plus the ones that aren’t ready yet.
Which connectors to add first
Start where your work already lives, not with the longest list:
- Email: Gmail, or Outlook if you’re on Microsoft 365. Almost every other workflow touches the inbox.
- Your documents: Notion or Google Drive, so Muse has context about your plans and projects.
- The one job that costs you the most time — a website, invoices, bookkeeping, leads. Our top 10 and small business picks are organized around those jobs.
What to check before you connect
- What it can read — and whether that includes anything sensitive.
- Whether it can act: send, publish, charge or delete.
- Whether changes are previewed first and can be undone.
- Whether it needs a separate account or paid plan with the underlying service.
Connectors that move money or publish to the public internet deserve the closest look. We hold them to a higher bar in how we rank.
More questions
Do I need connectors to use Muse?
No. Muse works in chat without any. Connectors are what let it work inside your other apps, such as reading your email or updating your website.
Are Muse connectors made by Meta?
Mostly not. Most are built by the company behind each app, such as Stripe, Notion or Zapier. Meta Business Manager is Meta’s own connector.
Is Muse available outside the US?
Meta describes Muse as available in the US and Canada. It hasn’t announced other countries.
