Is Muse free? What an invite code actually changes (November 2026)

Short answer: yes — Muse's basic features are free, and you don't need an invite code to use them. What a code changes is your starting token balance: enter one within 48 hours of signing up and both you and the code's owner get 1 billion bonus tokens. The bonus doesn't expire.

The catch is the window. The redeem field (app: Settings → Redeem token; web: Settings → General → Usage → Redeem invite code) only exists for the first 48 hours after signup. After that it disappears and a code can't be added later.

If you don't have someone's code, mine is:

UP711Q

Steps, in order: 1) Sign up. 2) Open the redeem field. 3) Type the code exactly. 4) Check the confirmation on your own screen — copying a code isn't redeeming it; the confirmation is the only proof.

For copy-paste, once more:

Why I bother writing this down: I run Muse on weekend side projects, and the starting balance is what let me delegate whole runs instead of rationing prompts. If you're starting this week, do the code step in the same sitting as the signup.
