Word cards (spaced repetition)
Paste a front/back word list and review it with Leitner boxes — cards you know come back later, cards you miss come back soon. Your decks and progress stay in this browser.
Decks and progress are never sent to a server; they are saved only in this browser (localStorage). To use another device, make a backup file and load it there.
Browser storage is unavailable here, so progress is not saved. It only works for this visit.
Keyboard: Space flips · → got it · ← missed it. Missed cards come back at the end of this session.
How review works & clearing progress
Cards live in boxes 1–5. Got it → up one box (revisit after: box 2 one day · 3 three days · 4 one week · 5 three weeks); missed → back to box 1 and asked again right away. Days follow this device’s today.
Separate front and back with a tab, |, =, :: or →. Cards with the same front are merged. Up to 500 cards, 200 characters per side.
For CSV the first two columns become front and back. Imported cards are appended to this deck.
FAQ
Can I continue on another device?
Nothing is stored on a server, so there is no automatic sync. Download a backup here and load it on the other device.
What if I clear my browser data?
Your decks and progress disappear with it. Download a backup of important decks now and then.
I want two cards with the same front.
Cards are identified by their front, so the same front merges into one. Add a hint after the front, like (noun) or (verb).
