Pricing questions
Is StudyInk really free?
Yes. Everything on this page belongs to the free account: lessons, SAT practice, the INKY tutor, the whiteboard, study groups and rewards. There is no trial countdown and no feature that unlocks after a payment.
Do I need a credit card to sign up?
No. You sign up with an email, Google or Discord and nothing is charged. Reading a sample lesson works without an account at all.
Where are the limits?
Cards you write yourself cap at 100 per lesson, which keeps one deck studyable and the list scrollable. AI features are rate limited per minute so a single account cannot starve the queue for everyone else. Generated decks are built from your lesson content, so they cost nothing to keep.
What does Ink cost?
Nothing. Ink is earned by studying and spent on marketplace items inside the platform. There is no way to buy Ink with money.
Will there be a paid plan later?
There is no paid tier today. If that changes, the terms will be published on this page before they apply, rather than appearing behind a signup form.
