Star Power & Usage
What star power is, how your balance works, what spends it, and what to do when you run out.
Last updated: June 23, 2026
Star power is the credit every AI action spends — continuing your text, rewriting, web search, generating an image. This page explains how your balance works, what uses it, and how to avoid running dry in the middle of a piece.
How your balance works
Your balance has two parts:
- Your monthly allowance. Every plan includes a set amount of star power that refills each billing cycle. This is most of what you'll use.
- Star packs. Extra credit added on top — for example from a promotion. Packs don't refill on a cycle, and some carry an expiry date. When you have both, Muses spends in the order that keeps your monthly allowance available longest.
You don't manage any of this by hand — Muses draws from the right place automatically.
What uses star power, and how much
Every AI action spends some star power. How much depends on two things:
- How much text is involved — a quick continuation costs far less than rewriting a long article.
- Which model you use — heavier models do more per request and cost more; the Default model is the lightest.
You're not charged per click or per message — you're charged for the work actually done. Routine writing on the Default model is inexpensive; reach for a heavy model on a long document and you'll spend more.
How much you get each month
| Plan | Star power per month |
|---|---|
| Free | 50,000 |
| Plus | 5,000,000 |
| Pro | 25,000,000 |
| Ultra | 100,000,000 |
Your allowance resets each month on your billing date — not on the 1st.
Where to check your balance
- The star power indicator in the app shows what's left at a glance.
- Your star power page (in your profile) shows your remaining balance, how much you've used this month, when it next resets, and a history of what spent it.
When you run out
If your balance reaches zero, AI actions pause and you'll see a message that you're out of star power. Your writing and everything you've saved are untouched — only the AI is paused. To keep going you can:
- Wait for your monthly reset (the date is on your star power page), or
- Upgrade your plan for a larger monthly allowance.
How not to get caught short
- Keep routine work on the Default model and switch to heavier models only when a piece needs it.
- Glance at the star power indicator during long sessions.
- If you regularly hit zero before your reset, your plan is probably a size too small — compare plans.
