Daily allowances reset at 00:00 UTC; monthly allowances on the 1st at 00:00 UTC.
Each plan has daily and monthly allowances. Daily allowances reset at 00:00 UTC; monthly ones reset on the first day of the month, also at 00:00 UTC. When you reach one, the site tells you which allowance it was and when it resets. Nothing else is blocked.
An AI question is one request to the AI: a step-by-step solve, a tutor reply or an FRQ grading. Reading a photographed or worded problem and then solving it counts as two. The calculators and the exact math engine do not count against any allowance.
Quiz and practice-exam allowances count scored attempts that are saved to your progress. You can always read the published questions and solutions.
You can use the solver, calculators and study pages without signing up. Visitors without an account get a small daily allowance of AI questions, uploads and quizzes; rendered videos and practice exams need a free account. The in-browser video lesson still plays without one.
Paid plans are billed through Stripe, so card details never reach this site. You can change plan, update your card or cancel from Manage billing on your account page; a cancelled plan stays active until the end of the period you paid for.
If online payment is not switched on yet, the paid plans show that clearly and no button pretends to take a payment.
The math calculators are free on every plan, with no allowance.
Yes. A free account includes daily AI questions, uploads, quizzes and monthly practice exams and video renders. All reading content and calculators are free for everyone.
Daily allowances reset at 00:00 UTC each day and monthly allowances at 00:00 UTC on the first of each month. Your account page shows what you have used and when each one resets.
That one feature pauses until the reset time and the message says which allowance it was. Calculators, the exact math engine and all study pages keep working.
Open your account page and choose Manage billing. Cancelling stops the next renewal; you keep the paid plan until the end of the current period.
No. Payments go through Stripe's hosted checkout and billing portal. This site only stores your plan, its status and when the period ends.
