Muse is Meta's personal AI agent — it browses the web, books things, manages email and tasks for you. It is still rolling out region by region, and its referral program is currently one of the most generous in AI: when a new user redeems an invite code within 48 hours of joining, both the new user and the person who shared the code get 1 billion Muse tokens.

This guide covers how the system actually works, how to redeem a code before the window closes, and how to share your own code without wasting it.

TL;DR — a working code

Invite code: P3HWFJ

  1. Create your account at muse.ai/join (or in the Muse app).
  2. Within 48 hours of joining, open Settings and redeem the code:
    • App: Settings → Redeem token
    • Web: Settings → General → Usage → Redeem invite code
  3. You get 1 billion tokens, and so does the person who shared the code with you.

If the code above has hit its limit by the time you read this, see the "where to find a fresh code" section below — and come back here once you have your own code to share.

Who can join Muse right now?

Muse is in a staged rollout. It launched in the US and Canada, with Japan and a few more regions opening since. If signup shows you a waitlist instead of letting you in, your region is not open yet — an invite code cannot bypass the waitlist, and no code seller can change that. Never pay for a code or an "activated account": codes are free by design.

The rules that actually matter

  • 48-hour window. The clock starts when you create your account, not when you find a code. Have a code ready before you sign up.
  • One code per account, ever. Your account can successfully redeem exactly one invite code in its lifetime. Pick one and use it — you cannot stack codes from several friends.
  • Both sides get 1 billion tokens. The bonus lands in your extra-token balance and does not count against the free weekly quota.
  • Referrers have a cap. Each person can earn the bonus from a limited number of successful referrals (Meta has described it as up to ~20 people). That is why public codes "run out" — once a code's referrals are used up, it stops working for everyone.
  • You cannot redeem your own code, and codes only work for genuinely new accounts.

Where to find a fresh code if this one is used up

Public codes burn out quickly, so freshness matters more than anything. Community pools where people post codes and mark them used include museai.codes, museaicode.cc and builtwithmuse.com. Tips:

  • Sort by newest and try the most recent codes first.
  • Have two or three backup codes ready before you start signup.
  • If a pool shows copy counts or "worked" reports, prefer codes other people recently confirmed.

How to share your own code effectively

Once you are in, your own code is in the app's Invite screen. What works:

  • Give it to people directly. A code handed to a friend who is signing up today converts far better than a code dropped in a random thread.
  • Post it where people are actively looking — dedicated invite-code pools and community threads beat general social feeds, because the reader is usually mid-signup.
  • Include the instructions. Many new users lose the bonus simply because nobody told them about the 48-hour window and the Settings path. The short version to copy with your code: "Join at muse.ai/join, then within 48 hours redeem this code in Settings → Redeem invite code — we both get 1 billion tokens."

Scams to avoid

  • Anyone selling codes or accounts. Codes are free and non-transferable in value; a paid code is used, fake, or attached to a farmed account that will be shut down.
  • Telegram "auto top-up" bots. Bots that promise to credit tokens if you send them your invite code work by redeeming it with fleets of bulk-registered fake accounts. Meta has already banned large numbers of Muse accounts over exactly this pattern — the tokens are not worth losing your account.
  • "Redeem here" links from strangers. Real redemption happens only inside the official Muse app or at muse.ai. Any other site asking you to log in to "claim" is phishing.

FAQ

I joined three days ago. Can I still redeem a code?
No — the redemption option disappears after 48 hours.

Can I redeem two codes to get 2 billion?
No. One successful redemption per account, for life.

Do bonus tokens expire?
Meta describes them as not expiring, and they sit outside your weekly free quota.

The code I tried says it is invalid or used up.
It has likely hit its referral cap. Grab a fresher one from a community pool and try again — as long as you are still inside your own 48-hour window.

Code shared in this post: P3HWFJ — join at https://muse.ai/join and redeem within 48 hours of joining, in Settings. We both receive 1 billion Muse tokens.
