Every way to use Muse.

Muse on WhatsApp

Muse lives inside WhatsApp as a chat. You message it like any contact — no separate app needed for the basics — and it is the same account as the app and the web.

1. 1Update WhatsApp to the latest version — the Muse entry point only appears on a current version.
2. 2Look for Muse in your WhatsApp chats. Message it like any contact — a question, a reminder, a task.
3. 3Anything that needs approval — a send, a purchase, a booking — asks first. Review what it did in the audit trail in the app or on muse.ai.

The country question, honestly. Meta has not published a per-channel country list for WhatsApp. What we can verify: WhatsApp is confirmed in the US. Some independent guides say US and Canada; at least one says US only — we are not going to pick a side. If you are in Canada, Japan, Singapore or Mexico and do not see Muse in WhatsApp, check whether the Muse chat appears in your WhatsApp, and see the region guide for what to do when Muse is not available where you live. And do not confuse the two products in WhatsApp: Meta AI is the chatbot built into WhatsApp in far more countries — it answers questions. Muse is the agent — it takes actions. Having Meta AI does not mean you have Muse.

Disconnecting: on muse.ai, open Settings and look for Messaging channels — that is where WhatsApp is connected and where you can remove it. Deleting the WhatsApp chat alone does not disconnect the account.

Muse for Mac

No, Muse does not need its own computer — the agent runs in Meta's cloud. Muse for Mac, launched 17–18 September 2026, is a free app from Meta that bridges the agent into the apps already on your Mac: Files, Mail, Messages, Calendar, Notes and Reminders. It is not in the Mac App Store — download it from Meta's Muse download page, sign in with a Meta account (no Facebook account needed), and choose what it may touch.

• Per-app permissions. Each of the six apps gets its own setting: Off, Read only, or Read and interact. Files needs Full Disk Access, which is opt-in through macOS Settings. Nothing on your computer is open until you grant it.
• Computer use is the next step, in early access. At Connect on 23 September 2026 Meta announced Muse can drive any app on your Mac, with your permission. It is rolling out gradually through an early access program — if you do not see it, that is the rollout, not a broken app.
• It asks first. Before sending an email or buying anything, Muse asks. Anything it deletes goes to your Trash.
• Do not confuse it with Muse Spark Open — a model that runs locally on Mac Studios. A model is not the agent; the agent does not run on your Mac.

Start read-only, the same as with any connector, and open up only the apps you actually want Muse working in. Keep the Mac app updated — a launch-day zero-day (reported by researcher Patrick Wardle) was hotfixed within hours, and official-source installs are the safe ones. Details: is Meta Muse safe? →

Muse in Chrome: the browser extension

“Muse from Meta” is the official Chrome extension, offered by Meta Platforms, INC. on the Chrome Web Store — free to add, version 2.0.65, updated 12 November 2026. Once installed, Muse lives in Chrome's side panel: a panel beside the page you are reading, instead of a new tab. The point is context — “fill out this form”, “compare this price”, “follow up on this refund” needs no copy-pasting, because Muse is already looking at the page with you.

1. 1Open the Chrome Web Store and search for “Muse from Meta” — the listing offered by Meta Platforms, INC. Click Add to Chrome.
2. 2Sign in with your Muse account. Your conversations pick up where you left them — it is the same agent.
3. 3Click the Muse icon in the toolbar to open the side panel, and ask it to do something on the page. Check its work — Meta's own warning is that Muse may be inaccurate or take unexpected actions.

• Desktop Chrome only. Extensions do not install on Chrome for phones — on your phone, use the Muse app or WhatsApp. Microsoft Edge can also install Chrome Web Store extensions.
• Not a second Muse, and not the Mac app. The extension is a door into the same agent; the Mac app reaches into local Mac apps instead.
• Approvals still apply before it sends, books, or spends.

Voice mode: talk to Muse out loud

Muse Realtime Voice officially rolled out on 5 November 2026 — live voice conversation in the US to start, on mobile, web, and Mac. Tap the phone icon in the top-right corner of the app or muse.ai to start talking. There is no setting to turn on and no waitlist: if the icon is not there, you are outside the US or the rollout has not reached you, and reinstalling does not help.

• Hundreds of voices, offered as styles. Pick one, or describe the voice you want — Meta's examples are a New Yorker's energy and a pirate's flair. You can ask for a faster or slower pace, or a specific accent.
• Three modes. Voice-only, the avatar beside the conversation, or full-screen. Muse hears you; it does not see you.
• US only to start. Canada, Japan, Singapore and Mexico have no date. Custom saved voices are in internal testing only, per September 2026 reporting. Voice conversations are announced as coming soon to Meta's AI glasses and Muse Charm — no confirmed date. And in WhatsApp, Muse is text-only.
• Approvals still apply. A voice conversation does not bypass them — sends, purchases, and bookings still ask first.

Muse Mail: your Muse's own email address

Since 10 November 2026, paid subscribers in the US and Canada can give their Muse its own email address, ending in @muse.ai. It is rolling out in waves, so the setup card may not have reached your account yet. Meta says it is coming to everyone, including free plans — no date given.

Meta's Connect recap, in its own words: “Muse will have its own email address that it can use to get things done, or even just as another way for you to communicate with it.” In practice: Muse uses the address to sign up for things and receive confirmations without using your personal inbox; you email tasks to it — forward a thread, send a document; and other people can write to your Muse directly to loop it into a conversation.

1. 1Look for a card headed “Give your Muse its own email”, with a Setup button, in the Muse app.
2. 2Tap Setup and pick your handle. The address ends in @muse.ai, and the handle is permanent — choose one you are happy to keep.
3. 3Verify your own email address in settings to finish setup.
4. 4No card yet? Your account is still in the queue. There is no setting that turns it on — check again in a few days, or ask Muse directly whether it is available.

On the free plan or still waiting? The Gmail and Outlook connectors are the email setup — they already do most of what people want the address for: connect read-only, and ask Muse to triage unread mail and draft replies. See the morning email digest workflow and the Gmail connector.

A new safety question. An address that belongs to the agent is a new surface for spam, phishing, and prompt injection. Meta has not documented how inbound mail is filtered, who can send to it, or what permissions inbound mail can trigger — wait for that before giving the address out.
