Credits and subscriptions

How are credits used?

Source processing and AI calls use credits based on actual usage, which varies with the model and content processed. Open Settings → Usage from your avatar menu to see your balance and consumption history.

How are upgrades billed? Can I downgrade?

Pay the full price of the new plan to start a new monthly period with its full allowance. The previous period’s actual payment is refunded to the original payment method in proportion to remaining plan credits. You can keep using your current plan while payment is pending. The preview is an estimate; the final refund uses the credits remaining when the new plan takes effect. A pending refund does not prevent use of the new plan. Purchased credits remain available. Free credits do not stack with the paid allowance. Downgrades are not supported.

How is yearly billing charged?

A yearly plan is one payment for twelve months; its price is shown per month. You get the same monthly credits as on the monthly plan, granted month by month rather than all at once. Yearly members can upgrade only to a higher yearly plan, not to a monthly one.

How do I cancel renewal?

Open Settings → Subscription & payments from your avatar menu, click Manage subscription, then click Cancel subscription on your current plan. Canceling renewal keeps your paid plan active through the paid period; you return to Free afterward. Purchased credits retain their original expiry dates.
