Multilingual spaced repetition
Remember every word you learn.
Learn vocabulary and phrases in the language you choose, with translations in the language you understand. Five boxes, one review queue, and a clear answer to “what should I study today?”
Example pair: English → Farsi. Your account can use any supported pair.
Three decks free, forever. No card limit.
The real Leitner system
Correct moves a card one box out. Wrong sends it back to Box 1. No hidden algorithm changing the rules on you.
Fast, timed rounds
Ten seconds a card by default, two recall choices, and a session that ends when it should. Turn the timer off whenever you need to.
Progress you can see
Box distribution, mastery, a thirty-day forecast, and the words that keep slipping — all from your actual reviews.
One card, five boxes
Box 1 uses a short learning window. Boxes 2–5 use a queue — cards become ready as you keep learning. This is the G5 method, not calendar scheduling.
- Box 1Cards you have learned enter here. After three hours they become ready to review.
- Box 2Cards wait in a queue and become ready as newer cards move forward.
- Box 3Cards wait in a queue and become ready as newer cards move forward.
- Box 4Cards wait in a queue and become ready as newer cards move forward.
- Box 5The final box — one successful review completes the card.
