What Muse Is and Who Can Use It

Several products share the name, so start by being exact. In this course, Muse means Meta's personal AI agent at muse.ai. An AI agent is software that carries out tasks for you, such as searching, filling in forms or building a document, instead of only answering questions in a chat box.

Three nearby names are easy to confuse:

• Meta AI is a separate Meta app with its own terms. Settings you change in one don't carry over to the other.
• Muse Spark is the model that powers Muse. It's the engine, not the app you use.
• Project MUSE (scholarly journals) and a "Muse" website builder are unrelated products that turn up in the same searches.

This matters in legal work. Say a colleague tells you "Muse's terms allow X" after reading a page about Meta AI or Project MUSE. That's the wrong document. Whenever you look up terms, privacy or prices, check that the page is on muse.ai or on a Meta help or newsroom page that names Muse. muse.ai sends you to a Meta sign-in, which confirms it belongs to Meta.

Meta launched Muse in the US on September 8, 2026. According to Meta's launch post, it differs from a chat tool in four ways:

• It acts. Muse runs on its own cloud computer, the Muse Secure VM (a virtual machine: a computer in Meta's data center that is assigned to you), with a web browser, a file system and a terminal.
• It works in the background. It keeps working on a schedule after you close the app and comes back when it needs your approval.
• It remembers. It keeps memories across chats, and you can edit them or tell it to forget things.
• It makes Artifacts. These are reusable outputs such as documents, PDFs, web pages and trackers.

Here's a legal example you'll build later: "Every Monday at 8 am, summarize new public developments on [topic] from [named court and agency sites], with a link to each primary source." Muse runs that in its own browser, produces a digest and keeps it ready for you.

The power that makes this useful is also the risk. An agent that can act for you can also act in ways you didn't intend. That's why the next lessons cover terms, data access and safe settings before you connect anything.

As of 2026-10-28, Meta's newsroom lists three markets:

• United States: launched September 8, 2026
• Canada: Meta's September 29 post says Muse "is available in the US and Canada"
• Japan: launched October 23, 2026, the first market outside North America

Meta hasn't announced a launch in the UK, the EU or Australia. Press reports say India has no date. You must be 18 or older, or the age of majority where you live (Muse Supplemental Terms).

Say a Toronto associate and a London colleague both want to run the same CLE tracker. The associate can sign up. The London colleague can't yet, and should not try a workaround.

Never use a VPN, a foreign app-store account or any other route around the region, age or terms limits. Meta's terms bar using Muse if you're legally prohibited from receiving Meta's services, and they bar circumventing other services' controls. For a lawyer, a workaround is also a candor and policy problem, on top of the breach of terms. Some websites publish such guides anyway. Ignore them.

Availability changes, so check Meta's newsroom before you rely on this list.

Meta's official sources confirm these platforms:

• iPhone (iOS) and Android: the mobile app
• Web: muse.ai in a browser
• Mac: launched around September 17–18, 2026. Meta's September 23 Connect post confirms that computer use (Muse working in local apps and files) is available on it. Download it only from ai.meta.com/muse/download/. Meta's pages don't state system requirements.
• WhatsApp: Meta's launch post says you can message Muse in WhatsApp, but there is no official step-by-step help page. Treat any WhatsApp number or link you didn't reach through Meta's own pages as a scam.

An iPad version has been reported in Canada but isn't confirmed. AI glasses are only described as "in the coming months."

A practical choice for legal teams: use the web or phone app at first. On a Mac, Muse can request Full Disk Access, which covers the whole disk. Don't grant that on a machine that holds client files. Lesson 3 covers Mac permissions in detail. Screens change between versions, so if a menu looks different from what's described here, look for the nearest equivalent.

Meta's help page "About Muse subscriptions" (read 2026-10-28) lists three plans:

Plan	Price	Usage
Free	$0	Usage limit not published
Power	$20/month	500M Muse tokens a week
Maximum	$100/month	3B Muse tokens a week

A token is the unit Meta uses to measure the work Muse does. Meta doesn't say how many tokens a task uses, so you can't work out in advance which plan your tasks need.

Billing renews monthly on your purchase date. Cancelling gives no refund unless the law requires one. Deleting the app doesn't cancel the plan. If you paid through the App Store or Google Play, cancel through that store. Prices are shown in dollars; Meta hasn't published official CAD or JPY prices. Meta may also end free access at any time.

There is no team plan or shared workspace. Each person needs their own account and subscription. A practical approach for a few light standing tasks, such as a weekly digest and a CLE tracker: start on Free, and upgrade to Power only if you keep hitting the limit. Get your firm's approval before you spend anything.

Web guides about Muse often repeat numbers and features that Meta hasn't confirmed. Teach yourself to sort them.

Unverified or conflicting figures:

• "Free gives about 100M tokens a week": Meta publishes no free-tier number.
• "Power from $16, Maximum from $80": conflicts with Meta's official $20 and $100.
• "1B bonus tokens with an invite code": unverified. Don't share referral codes.
• "A card is required to sign up": unverified.

Announced but not available. Don't plan work around these:

• Voice mode, Muse Realtime Avatar and a Muse email address, all announced September 23 with no ship date
• Phone calls to businesses (public status unconfirmed; an employee-only test was rolled back)
• AI glasses ("in the coming months")
• Confidential VM, encryption with a key only you hold ("later this year")

Confidential VM matters most for lawyers. Until it ships, Meta can access your data when needed to run the service. That's one reason this course keeps client information out of Muse completely. Lesson 2 covers it.

Before setting anything up, write a short dated note. You'll attach it to the approval request you send whoever signs off on new tools at your firm or department, and you'll update it whenever Meta changes something.

Open Meta's subscriptions help page and the newsroom posts, then fill in this note:

Muse eligibility note: [your name], checked [date]
Country of residence: [US / Canada / Japan]. Confirmed on Meta newsroom: [yes/no]
Age 18+ or local age of majority: [yes/no]
Device I'll use first: [web at muse.ai / iPhone / Android / Mac, no Full Disk Access]
Plan: [Free / Power $20 / Maximum $100]. Price confirmed on Meta's subscriptions page: [yes/no]
Intended use: standing tasks with no client data
Firm or department AI-policy approval: [approver, date, or "pending"]
Recheck before relying on any of this: [date]

It worked if every line is filled in from an official Meta page and the note is dated.

If it isn't working: if your country isn't listed, stop here and wait for an official launch. If the help page shows different prices or plan names than this lesson does, trust the page and update your note, because these details change.
