Credits for AI marking

One balance for every marker on the site, for students and teachers.

  • 5 an IA draft marked, with the three moves worth a mark
  • 5 a moderation check of your own marks on a script
  • 1 a whole practice paper’s marking checked

Sign in first, then buy: the credits go to your account. We email you a sign-in code, no password.

Paid on Stripe in your currency; this site never sees a card number. The credits reach your account within a minute. Teachers can buy for a class and hand out a class code. A credit spent on a marking isn’t refunded; a marking that fails gives its credit back.
