Billing questions
What is a credit?
A small unit of usage. Each message shows its credit cost before you send it – fast models use about 1 credit, top models more. Lessons, quizzes and the tutor chat inside courses never use credits.
Do unused credits carry over?
No. Your plan’s credits reset at the start of each billing month.
Can I cancel or get a refund?
Cancel any time from your account and keep access until the end of the paid period. First-time payments can be refunded within 14 days – see our Refund Policy.
