FAQ
Everything you need to know about pricing and purchases
Can I use a word pack and membership at the same time?
Yes. They stack — membership daily quota is consumed first; once exhausted, your word pack balance is used. Word packs never expire.
Do word packs expire?
No. Word 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 word pack balance covers the rest; the quota resets the next day.
What payment methods are supported?
WeChat Pay is currently supported. Credits are added instantly after payment.
Can I get a refund?
Word packs cannot be refunded once used; unused packs can be refunded within 7 days of purchase. Memberships are non-refundable after activation.
