Pricing
Every plan unlocks the same thing: the complete experiment library, the sandbox, courseware downloads, and the AI tutor without a daily cap. The only difference is the billing period.
When the trial ends, the plan you selected renews automatically at the price shown below — $9.99 every month, $49.90 every 6 months, or $89.99 every 12 months. The renewal amount and date are shown again on the checkout page before you pay. Cancel before the trial ends and you are charged nothing further.

All prices are in USD and exclude tax. Sales tax, VAT and GST are
calculated at checkout from your billing country and collected by Creem as merchant of record.
Cancelling. Cancel from your account page at any time — it takes two clicks,
no email and no phone call required. Access continues until the end of the period you have
already paid for, and the subscription does not renew.
Refunds. Unused subscriptions can be refunded within 14 days —
see the refund policy. Refunding a subscription also revokes any
offline licence issued under it.
Payment methods. Card, PayPal, Apple Pay and Google Pay, handled entirely by
Creem. We never see or store your card details.
Classroom and institutional licences. Volume pricing for schools and tutoring
centres is quoted individually — write to us at the address below.
Acceptable use. The AI tutor may not be used to generate sexual or adult
content — see the Acceptable Use Policy.
