Create, study, and print two-sided flashcards with spaced repetition and progress tracking.
You enter a question and its answer for each card you want, and the tool builds a two-sided deck from the pairs: one side shown, the other hidden until you ask to reveal it. Study sessions pull from a spaced-repetition schedule, so a card you know drifts further into the future while a card you miss comes back sooner, and progress per card is tracked as you go. When you want paper, the deck lays out as front-and-back sheets to cut apart. The usual surprise is the print step: two-sided cards only line up if the sheet comes out of the printer the way the layout expects.
Every card has exactly two sides, a front and a back, and the deck is created from the pairs you provide: each pair becomes one card. The tool works only with what you type or paste, so the deck is only as good as the pairs you enter: typos, missing answers, and duplicated lines pass straight through into the cards. Check the pairs before studying.
Spaced repetition runs on intervals: each card carries its own next-review date, and the study queue is built from those dates, not from deck order. Answer correctly and the interval grows, so the card is due again later; answer wrong and the interval shrinks, so it returns sooner. The schedule is rebuilt from your answer history, so a card's next appearance depends on how you graded it last time.
Because the study queue is built from due dates, not deck order. Only cards whose review date has arrived appear, so a large deck may present a small session. A card you answer correctly today will be absent tomorrow and come back when its interval elapses. To review everything at once, you would have to study until the due queue is empty.
No. The tool runs entirely in your browser and does not upload your cards anywhere, so the deck exists only on the machine and browser where you created it. Once the page is loaded, studying and printing work offline. The trade-off: a different device or a cleared browser will not have your deck, so keep the source list of pairs somewhere.
