In short, Quotas are mainly used for basic detection functions (such as AI detection and OCR recognition) and are suitable for routine checks. Credits are a premium currency, specifically for core advanced features (such as Humanize AI Rewrite or Deep Plagiarism Check). If your main goal is to pass AI detection, please pay attention to the number of “Credits” you have.
Yes, subscriptions are set to auto-renew by default to ensure uninterrupted service. You can cancel your subscription at any time in your “My Account” settings. After cancelling, you can still use the service until the end of your current billing period, and you will not be charged again.
Yes, you can request a refund. If you forgot to cancel your subscription before the renewal date, and you have indeed not used the service during the new billing cycle, please email our customer support team as soon as possible. We will review based on your account’s actual usage records and do our best to provide a reasonable solution. To avoid unexpected charges in the future, we also recommend that you cancel auto-renewal in your settings first.
No. Monthly credits and quota granted by subscription will reset at the end of each billing cycle. If you want credits that “never expire,” we recommend purchasing our credit top-up packages.
Please email our customer service team directly. We will provide you with a customized solution according to your needs.
Yes. Cancelling your subscription simply means it will not automatically renew for the next period. Your current membership benefits, including any remaining credits and quota, will remain available until the end of the current billing cycle.
No, we provide a generous free trial for you to try out advanced features. Of course, we recommend choosing the Basic subscription, which includes credits that are usually sufficient for daily needs and is more cost-effective.
Monthly plans renew automatically on the billing date. If the charge fails (for example, insufficient card balance or a payment error), your membership will expire and the plan's quotas and credits will be reset to zero. However, your auto-renewal subscription is not automatically cancelled by the system—the subscription agreement stays in place and the system will retry charging later.
A failed charge only means that billing period's membership has expired; it does not turn off auto-renewal. If you have not cancelled manually, when your card has sufficient balance the system will retry the payment and restore your monthly membership. To stop renewing, please cancel your subscription manually.
Quotas and credits included with that month's plan are cleared when the membership expires. Only credits from separately purchased top-up packs are kept permanently and are not affected when the subscription lapses.
We support major credit cards (Visa, Mastercard, Amex) as well as PayPal and other popular payment methods.
Absolutely secure. All transactions are encrypted and handled by international third-party payment platforms such as Stripe. We do not and cannot store any of your sensitive credit card information.
Once your payment is successful, you can download your receipt or invoice in 'My Account > Billing History'. If you need to add your company name or VAT number, you can usually do so on the billing details page.
