¥1 buys 1,000 Credits. Credits are settled against the input, output and cached token counts the model actually reports, down to fractional amounts — you pay for exactly what you use.
Frequently asked questions
Do the document tools cost anything?
No. Word to PDF, PDF split and merge, Excel cleanup and the other 32 deterministic tools are free forever, and no account is required.
Do Credits expire?
No. Both purchased and granted Credits stay in your balance indefinitely.
What happens to my balance when a plan expires?
It stays. Expiry only removes the monthly grant and membership benefits; your existing Credits remain usable.
Can I get a refund?
Yes. Contact support with your order number and we will refund through WeChat Pay. Granted Credits are clawed back in proportion to the refund.
Which payment methods are supported?
WeChat Pay QR code today. Business customers needing bank transfer or invoicing should contact us.
