Hanmargin 皮皮改作文
Pricing
Hanmargin (皮皮改作文) is an AI-assisted essay marking tool for teachers of Chinese as a first, second or heritage language. Teachers photograph handwritten Chinese essays; the app recognises the text, drafts feedback and margin comments in the teacher's own style, and the teacher reviews and finalises every comment. The app interface is in Chinese (Simplified or Traditional).
Free credits cover everyday use. If you mark a lot, buy a credit pack. One-time payment: no subscription, no auto-renewal, and purchased credits never expire. Full refund for any reason within 14 days.

How credits are used
Credits are deducted by actual AI usage. Recognising, marking and annotating one essay usually takes 3–10 credits, depending on length, number of photos and features used. Chat is charged per turn by actual usage. Every deduction is listed in your credit history. Free and purchased credits share one balance.
