Review purchaseHow do credits work?
Solutions, follow-ups, image recognition and AI answer checks cost 1 credit each. A practice set costs 2; a video lesson costs 20 (up to 10 narrated segments). All features share the same balance.
Expiry & failed generation
Subscription credits expire at the end of their paid period and do not roll over. Expiring credits are used first. Failed generation refunds credits; abandoned requests are released by scheduled cleanup. The final charge is shown at Stripe Checkout.
