Meta Muse Invite Code: 1 Billion Tokens Each, How to Redeem

Meta’s personal AI agent, Muse, became available in Japan on October 23, 2026. Japan is the first place outside North America to get it, so if you live here, you can sign up today with a Japanese phone number or an email address.

If you’re about to start, don’t skip the invite code. Enter it in Settings within 48 hours of creating your account, and both you and the person who invited you receive 1 billion Muse tokens. The window is short, so it’s easiest to do it right after you log in.

Our invite code is MYI9YI. When it’s used, this site also receives tokens.

How to sign up and enter the invite code

Muse runs on the iPhone and Android apps and on the web at muse.ai. You need a Meta account to log in, but you don’t need Facebook or Instagram: a phone number or email address is enough to create one.

1. Open muse.ai or install the Muse app.
2. Create an account with your phone number or email address.
3. Within 48 hours, open Settings and enter MYI9YI in the invite code field.
4. Once the code is accepted, you and the person who invited you each get 1 billion Muse tokens.

How much is 1 billion tokens? Compared with the paid plans

Muse is free to use with usage limits. Two paid plans raise the weekly limit for heavier users.

The 1 billion tokens from an invite equal two weeks of the Power plan. Meta doesn’t say how many tokens a task uses, so we can’t translate that into a number of tasks, but it’s a useful buffer for when the free allowance runs out.

Paid plans are for users 18 and over and renew every month until you cancel. Reports of the yen prices vary, so check the amount shown on the purchase screen in the app.

What Muse can do

Muse is an AI agent that gets things done when you ask in a chat. Beyond answering questions, it can send emails, book trips and fill in web forms for you. Longer tasks keep running after you close the app, and you get a notification when your approval is needed. It runs on Meta’s AI model, Muse Spark.

• Sort email, draft replies and send them (Gmail)
• Check and add events (Google Calendar)
• Book travel and hotels (Trip.com, Agoda, Klook)
• Shop online (Stripe, Shopify; it always asks before buying)
• Turn a recipe reel you saved on Instagram into a shopping list

For Japan, integrations with Mercari, Money Forward ME and Ticket Pia are in the works. Advanced voice mode, the real-time avatar and a dedicated Muse email address don’t have a Japan release date yet.

Privacy and safety: what to know first

Handing your email and calendar to an agent naturally raises questions about what it can see and do. Here’s how Meta says Muse works:

• It asks for your approval before important actions such as sending an email or buying something, and you can review a full history of what it has done and plans to do
• Muse can’t see your passwords or payment methods; when shopping, a one-time card number is generated at checkout
• Your conversations aren’t shared with Meta’s ad systems, and you can opt out of having them used for AI training
• You can change or revoke app permissions at any time

Keep in mind that these are Meta’s own claims. Some international media have pointed to Meta’s past privacy problems and urged caution. When you connect your email or calendar, grant only the access you actually need.

Once your account is set up, go to Settings and enter the invite code first. After 48 hours, you can’t claim it.
