Plans & Pricing
The four plans, how to pick by need, and how upgrades, cancellation, and billing work.
Last updated: October 11, 2026
Muses has four plans. Plus, Pro, and Ultra share the Clio and Calliope model choices and unlimited projects and articles; they differ by monthly star power. Free uses Clio and is limited to 5 projects and 50 articles.
Pick by what you need
| Plan | Best for | Star power / month | Models |
|---|---|---|---|
| Free | Trying Muses and occasional writing | 50,000 | Clio only |
| Plus | Regular writing with room to spare | 5,000,000 | Clio / Calliope |
| Pro | Heavy, near-daily writing and long pieces | 25,000,000 | Clio / Calliope |
| Ultra | The highest volume of work | 100,000,000 | Clio / Calliope |
Free also caps you at 5 projects and 50 articles; paid plans remove those limits.
What each plan costs
| Plan | Monthly | Yearly |
|---|---|---|
| Plus | $19.99 | $199 (save ~17%) |
| Pro | $59.99 | $599 (save ~17%) |
| Ultra | $199.99 | $1,799 (save ~25%) |
All prices are in USD. Paying yearly bills the full year once and costs less than twelve monthly payments. StarPower still refreshes monthly on your billing anchor. The app shows the exact plan, cycle, and charge again for confirmation before checkout.
Changing your plan or billing cycle
- Moving to a higher plan on the same billing cycle can use the existing immediate upgrade flow, with the difference calculated for the remaining period.
- Moving to the current or a lower plan, or switching between monthly and yearly billing, is not a self-service change in this release. The app explains the limitation and links to the billing portal.
- An admin-gift subscription can start a new paid Checkout instead of using the billing portal.
Cancelling — and coming back
You can cancel two ways:
- At the end of your billing period (recommended) — you keep full access and your remaining allowance until the period ends.
- Immediately — access ends right away.
If you cancelled at period end and change your mind, you can resume before the period actually lapses, and nothing is interrupted.
Managing your billing
Paid subscribers can open the billing portal from their profile to update a payment method, download invoices, or review subscription details. (Subscriptions given as a gift are managed for you and don't use the portal.)
