Common questions about pricing.
Is there a free plan?
Yes. Signing up is free and takes no card. Your first note is a real study kit from your own lecture, shown as a preview: the first summary section, 10 flashcards, 4 quiz questions and 5 concepts. You can review those cards and questions with spaced repetition for free. The rest of the kit stays visible but locked. A free trial of Pro opens all of it, or one credit opens one lecture in full with its Feynman test. The free study tools also give you 3 runs a day with no signup.
Subscription or credits, which should I pick?
Pick Pro if you study often: the full kit on every lecture, bigger uploads, full-depth kits, and all the AI tools. Pick credits if you're occasional: pay per lecture, they never expire, and they keep working whether or not you subscribe.
Why is web cheaper than the mobile app?
Apple takes a cut of in-app purchases. On the web there's no platform cut, so the web price is lower.
Can I get a refund?
Yes, 30 days, no questions asked. Lifetime is fully refundable within 30 days too.
What payment methods do you accept?
Card (Visa, Mastercard, Amex), Apple Pay, and Google Pay.
What are credit packs?
If you don't want a subscription, buy a pack of lecture credits. One credit processes one lecture into its full kit, with the Feynman test included, and never expires.
