Why one generation a day and not none
Every AI generation costs real money to run. Apps in this category resolve that in one of three ways: a hard trial that expires, a sign-up wall that turns you into a mailing list, or a subscription before you've seen the product work. We picked a fourth — a daily allowance that never runs out.
It has an accidental benefit. One deck a day, reviewed, is a better study pattern than six decks on Sunday that you never open again. The students who get the most out of spaced repetition are the ones with small decks and a daily habit, which is roughly what the free tier pushes you towards. See how the scheduling works for why volume is the usual way people fail at this.
Who should upgrade — and who shouldn't
Upgrade ifyou're building decks across a whole syllabus in concentrated sessions: a med student working through a module, someone converting a year of NCERT chapters before an exam, a teacher making decks for a class.
Don't bother ifyou're studying one subject at a normal pace. One deck a day, kept up, is more material than most people can actually review. We'd rather say that here than sell you something you won't use.
What the free tier is not
It isn't a seven-day trial, it doesn't need a card on file, and it doesn't lock your existing decks behind a paywall later. If you never pay, you keep 1 generation a day and unlimited reviewing indefinitely.
Ads, plainly
The free tier carries ads. That's what funds the daily AI generations for people who never pay a penny.
What we do with your data
Your decks are stored on your device. When you generate cards, the text or image you provide is sent to our AI provider so it can write them — that's the whole data flow, and the privacy page spells it out including what the ad SDK sees.
