Flashcard Maker: Spaced Repetition and Paper Cards
Students, teachers and parents can make question-and-answer decks, study due cards with spaced repetition, import CSV or Quizlet text, and print paper cards with mirrored backs.
Flashcard Maker: Spaced Repetition and Paper Cards: Make separate revision decks for different subjects, then study the cards that are due and grade how well you remembered each answer. SM-2 spaced repetition helps you practise difficult cards again and leave longer gaps between successful reviews. You can also print cards to cut out and use away from the screen.

For students, teachers and parents: make small question-and-answer cards and review the cards that are due. Decks and review history stay in this browser only. They can be lost when site data is cleared; export a backup.

SM-2 starts at ease 2.5 and schedules successful reviews after 1 day, 6 days, then the previous interval multiplied by the previous ease, rounded up. Again, Hard, Good and Easy map to recall grades 0, 3, 4 and 5. Again resets the repetition count; grades below Good stay due for another review today. CSV backups contain card text; browser storage also retains the schedule. Piotr Woźniak: SuperMemo SM-2 description
Spaced repetition
SM-2 spaced repetition is described by Piotr Woźniak at SuperMemo: https://www.super-memory.com/english/ol/sm2.htm . Successful reviews start with gaps of 1 day and 6 days, then become farther apart according to how well you remember the card. If you forget an answer, you begin again with shorter gaps. Again and Hard cards need another review today.
Card exchange and paper layout
To bring cards from a spreadsheet, use two columns for the front and back with no header row. CSV quoting lets you include commas, quotation marks and line breaks in a card; RFC 4180 explains the format: https://www.rfc-editor.org/rfc/rfc4180 . You can also paste a term, a tab and its definition on each line. Print on A4 (210 × 297 mm) or Letter (215.9 × 279.4 mm), using long-edge duplex binding so the mirrored backs line up with the fronts.
How to use it
- Create a deck, type front and back text, or import two-column CSV or tab-separated text without headers.
- Study due cards, flip with Space or a tap, and grade your recall.
- Export a CSV backup, or print paired front and back sheets using long-edge duplex binding.
Privacy & limitations
Decks stay in localStorage in this browser only. Clearing site data can erase them. Export a CSV backup; CSV saves front/back text, while review history stays in browser storage.

Frequently asked questions
What do the four grades mean?
Choose Again if you could not recall the answer, Hard if you recalled it with difficulty, Good if you recalled it correctly after a hesitation, and Easy if you recalled it straight away. Again and Hard cards come back for another review today.
Can I import Quizlet cards?
Yes. Paste or upload term, a tab, and definition on each line. CSV supports quoted commas, quotation marks and newlines. Use two columns without a header row.
Where is my backup?
Use Export CSV backup and keep the downloaded file somewhere safe. It contains card text rather than review history. Cards do not sync between devices, and clearing browser site data can erase local decks.
How should I print the backs?
Choose the matching A4 or Letter size, print at actual size without browser headers or footers and use long-edge duplex binding. The back columns are mirrored. Test one sheet and shorten text that exceeds a paper slot.
