Muse Invite Code: How to Get 1 Billion Free Tokens (Working Code, 21 Spots Left)

Full disclosure first: this is my own invite code, and yes — I get the same bonus when you use it. That is exactly the deal for both sides.
The deal
Muse is Meta's personal AI agent. It doesn't just chat — it can browse the web, work with your email and calendar, build documents, and keep running scheduled tasks in the background while you're away.
Right now, a new user who redeems an invite code within 48 hours of signing up gets 1 billion Muse tokens — and the person who shared the code gets 1 billion too. The bonus sits on top of the free weekly limit.
My code
XFYS9T — 21 spots left as of Oct 27, 2026. I'll update this count as spots are used; if it ever shows as full, any other valid code gives you the same bonus.
How to redeem (do this in your first session)
Sign up at muse.ai/join
Within 48 hours of creating your account, open Settings.
Web: Settings → General → Usage → Redeem invite code
Mobile app: Settings → Redeem token
Enter XFYS9T and confirm.
Check your balance — the 1 billion shows up as "Additional tokens".
The one rule people miss
The 48-hour clock starts when you create the account, not when you find a code. If you signed up two days ago, no code can help anymore — the redeem option is gone. So: have the code ready before you sign up, and redeem before you start exploring.
