How to Sign Up for Muse AI: A Step-by-Step Guide (2026)

To sign up for Muse AI, download the Muse app on iOS or Android, open muse.ai in your browser, or install the Mac app. You must be in the US or Canada and at least 18 years old. Sign in with your Meta account — you can create one with an email address, phone number, or your Facebook or Instagram login. The free tier costs nothing and includes a weekly usage allowance.

That is the whole process in a nutshell. Below is the full step-by-step walkthrough: who can sign up, what you need before you start, how to do it on each device, and the honest truth about the free and paid plans.

What Is Muse AI?

Muse is Meta’s personal AI agent, launched in 2026. Unlike a simple chatbot, it can actually do things for you — send emails, turn notes into shopping lists, research topics, book things, and generate images and videos from text prompts. It works in its own cloud-based virtual machine, so it does its heavy lifting in the cloud rather than on your phone or computer.

It is also built into the apps you may already use. Meta says talking to Muse works like messaging another person, including inside WhatsApp.

Who Can Sign Up for Muse AI?

Before you try, check these three things:

• Location: US or Canada only. Meta first launched Muse in the US and then opened it to Canada. As of 2026, those are the only two countries — Meta has not announced dates for a wider rollout. If you are outside the US or Canada, the app or site may tell you it is not available in your region yet.
• Age: 18 or older. You must be 18 or older to sign up for Muse.
• A Meta account. You do not need to be an active Facebook or Instagram user — but you do need a Meta account to sign in.

What Do You Need Before You Sign Up?

Gather these before you start so the process goes smoothly:

• An email address or phone number you can verify — you will need to receive a confirmation code.
• Your date of birth, to confirm you are 18 or older.
• A phone (iPhone or Android), a Mac, or just a web browser — one is enough.
• Patience if you hit the rollout queue. Because Muse is rolling out in stages, some users may need to wait even in supported countries.

How Do You Create a Meta Account for Muse AI?

Your Meta account is your login key. Here is how to get one if you do not have one:

1. Use your Facebook or Instagram account. If you already log into Facebook or Instagram, you can use that same login — fastest option.
2. Create one with your email address. You only need to provide an email address, your name, your date of birth, and a password. You can only create one Meta account per email address.
3. Create one with your phone number. A phone number works too.

You do not need to already use Facebook to get a Meta account. An email address alone is enough.

How to Sign Up on iPhone or Android

The phone apps are the most popular way to sign up:

1. Download the Muse app from the Apple App Store (iPhone) or Google Play Store (Android).
2. Open the app and tap sign in. You will be asked to sign in with your Meta account.
3. Create your Meta account if you do not have one, using your email, phone, Facebook, or Instagram.
4. Enter your verification code. Meta will send a code to your email or phone — type it in to confirm it is really you.
5. Enter your date of birth if asked, to confirm you are 18 or older.
6. Create your Muse agent. Follow the prompts to name and set up your agent.
7. Choose which apps it can access. Muse may ask to connect to things like your email or calendar. You get to approve each permission — only connect what you are comfortable with.

How to Sign Up on the Web

No phone handy? You can sign up in a browser:

1. Go to muse.ai on any computer or phone browser.
2. Sign in or create your Meta account — same options: email, phone, Facebook, or Instagram.
3. Verify with the code sent to your email or phone.
4. Set up your agent following the on-screen prompts.

This is also how Windows users get in — there is no native Muse app for Windows, so Windows users sign up and use Muse through muse.ai in their browser. Because Muse does its real work in its own cloud virtual machine, the experience does not depend much on your device.

How to Sign Up on a Mac

Meta also offers a Mac app:

1. Download the Muse app for Mac.
2. Sign in with your Meta account or create one with your email or phone.
3. Complete verification and setup the same way as on phone or web.

Can You Use Muse AI Inside WhatsApp?

Yes. Meta says talking to Muse works just like messaging another person inside WhatsApp. If you already chat in WhatsApp, you can talk to Muse there too — no separate download needed. You still need to be signed in with your Meta account and in a supported region.

How Much Does Muse AI Cost? Free vs Paid Plans

Signing up is free, and there is a free tier — but there are paid plans too. Here is the honest breakdown as of 2026 (plans and prices change, so check Meta’s official pricing before paying):

• Free. A weekly usage allowance at no cost. That is plenty for everyday tasks — emails, research, lists, questions.
• Paid tiers. Higher weekly allowances for heavier users and professionals running big workloads.

Meta describes the free tier as free to use — the paid plans buy you more usage, not access. One tip: stay on the free tier first and upgrade only if you actually hit your weekly allowance. The app shows your usage so you can see where you stand.

What Should You Do Right After Signing Up?

Once you are in, do these five things:

1. Type your first goal in plain words. Tell Muse what you want, the way you would text a person.
2. Connect one or two apps. Start small — maybe your email and calendar. You can add more later.
3. Approve permissions deliberately. Muse asks before taking sensitive actions, like sending an email or spending money. Read each request before you say yes.
4. Check your usage. Get a feel for how much of your free weekly allowance you use.
5. Explore the free features. Try the image and video generation from text prompts — they are part of the free experience.

Frequently Asked Questions

As of 2026, Muse is only available in the US and Canada. Meta has not announced dates for other countries. If you are elsewhere, you will need to wait for the rollout.

No. You need a Meta account, which you can create with just an email address or phone number. If you already use Facebook or Instagram, you can use that login too — but it is not required.

The Bottom Line on Signing Up

Signing up for Muse AI takes a few minutes: grab the app or open muse.ai, sign in with a Meta account (email works fine — no Facebook required), verify your code, confirm you are 18+, and you are in. Just remember it is US and Canada only for now, and start on the free tier — the free weekly allowance covers everyday use for most people.
