All calculators are free. Upgrade for unlimited AI credits, priority solving, and an ad-free experience.
Purchase one-time credit packs. Credits never expire and stack on top of your monthly plan.
One credit equals one AI solve request. Standard problems (triangles, circles, angles) cost 1 credit. Vision problems (photo upload) cost 3 credits. Complex proofs cost 2 credits.
Monthly plan credits reset at the start of each billing cycle. Unused credits do not roll over. One-time credit pack purchases never expire.
Yes. Cancel any time from your dashboard. Your plan stays active until the end of the current billing period.
Every new account starts with 30 free credits — no credit card required. This lets you fully test AI solving before upgrading.
Our AI engine automatically selects the best approach based on the problem type — standard geometry, proofs, or visual problems. Pro and Team plans get priority access to more powerful reasoning capabilities.
No. All calculators run instantly without an account. An account is only needed for AI solving (which uses credits).
Yearly billing gives you the same credits every month but at a discounted rate — you pay upfront for the full year. You can switch between billing cycles when you upgrade.
