FAQ
Everything you need to know about pricing and purchases
Can I use a credit pack and membership at the same time?
Yes. They stack — membership daily quota is consumed first; once exhausted, your credit pack balance is used. Credit packs never expire.
Do credit packs expire?
No. Credit packs are valid indefinitely after purchase. Use them at your own pace.
How many words does generating content consume?
Most features deduct at a 1:1 ratio. Some advanced features (e.g. stronger models or special pipelines) apply a multiplier, which is shown before you confirm.
Is Pro membership truly unlimited?
Pro members have a generous daily quota that most users never hit. If you do reach it, your credit pack balance covers the rest; the quota resets the next day.
What payment methods are supported?
Alipay and WeChat Pay are currently supported. Credits are added instantly after payment.
Can I get a refund?
Credit packs are non-refundable once activated. Unused credit packages are eligible for refund applications within 7 days of purchase. Membership plans cannot be refunded after activation; please purchase as needed. Refunds are available for issues caused by system failures or generation errors, while refunds will not be granted for user operational mistakes.
