Credits & plans
What a credit is, what each tool costs, and how the plans and top-ups work.
Credits power the AI tools, roughly one credit per AI call. You get free credits to start, and you can subscribe or buy top-ups for more.
What each tool costs
- Grade a paper: 1 credit
- Quiz: 2 credits per quiz, no matter how many take it
- Worksheet or Practice Generator worksheet: 5 credits
- Practice rerender after the first successful render: 1 credit
- Parent Report, Progress page, Personalized paper: 1 credit each
- Lesson Planner: 1 credit
- Class Deep-Dive: 1 credit per student, minimum 2 and maximum 30
- Practice Arcade shared question set: 5 credits
- Practice Arcade personalized class set: 2 credits per student, minimum 5
Free credits & plans
- Free: 10 credits to try without an account, plus 10 free credits a month once you sign up.
- Pro ($15/mo): 500 credits a month. Power ($30/mo): 1,200 credits a month.
- Top-up ($10 = 300 credits): stackable and never expires.
Promo credits, when present, drain first. Otherwise credits drain top-up first, then your monthly free, then your subscription, so the credits that never expire are spent before the ones that refresh anyway. If a run fails, the credits for it are refunded automatically. Practice Generator's first printable render retries once on failure; if both attempts fail, the original 5 credits are refunded.
