Choose Your Plan

Registration and invitation reward stars never expire and remain in your account permanently. Subscription stars are valid for the current billing month only—any unused stars expire at the end of the month. Stars are always consumed on an earliest-expiring-first basis, so subscription stars are used before your permanent reward stars.

Detection: 0.1 stars per 2000 words (minimum 0.1 stars); Optimization: 1 stars per 2000 words (minimum 1 stars). Chinese text is billed by character count, English by word count. Stars are deducted from your account balance on a priority basis.

Stars are the virtual credits used to power AI detections and content optimizations. Purchase star packages to get started.

Subscribers get monthly stars. You can also earn extra stars by inviting friends.

Upgrades take effect immediately, starting a new billing cycle from today. The prorated charge is calculated as: Prorated Charge = (New Plan Price − Current Plan Price) × Remaining Days ÷ Total Days in Billing Cycle. The difference is charged immediately by Creem, and the next billing date is based on the new cycle (actual payment amount may include applicable taxes, as shown on the checkout page).

After downgrade, current subscription benefits remain valid until the end of the current billing cycle. The new tier takes effect at the commencement of the subsequent billing period. Paid fees for the current period are non-refundable and are not eligible for pro-rata credit or reimbursement.

After canceling auto-renewal, your current subscription benefits remain valid until the end of the current billing cycle. Paid fees for the current period are non-refundable.

You can reactivate a canceled subscription at any time before the current billing cycle ends. All benefits take effect immediately upon reactivation, and the subscription will continue to auto-renew at the original tier.
