Where are my cards saved?

Cards are saved in your browser's local storage, not on a server. They'll still be there the next time you open the same browser, but they won't show up on a different device or browser.

Is the card order always random?

Yes. The order is reshuffled using the Fisher-Yates algorithm whenever you add or delete a card, and whenever you press "Reshuffle".

I made a mistake on a card. Can I edit it?

There's no edit feature yet — delete the card from the card list and add it again with the correct content.

Flashcards - Random-Order Study Cards

What are flashcards?

Flashcards bring the classic study method — a question on the front, an answer on the back, flipped through repeatedly to memorize — onto the web. This tool lets you freely add your own question-and-answer pairs, and shuffles the card order randomly using the Fisher-Yates algorithm every time you study, so you can't just memorize the sequence. Clicking a card flips it with a smooth animation to reveal the answer, and every card you create is saved to your browser's local storage, so it's still there even after a refresh or a return visit later.

How to use it

Enter a question and answer in the card management area below and press "Add Card" to add it to your study list. On the study screen, click a card to flip it and reveal the answer, use "Previous"/"Next" to move between cards, or "Reshuffle" to randomize the order again. Cards you no longer need can be removed with the "Delete" button in the card list.

When it comes in handy

Repeatedly memorizing foreign-language vocabulary or exam terms
Testing yourself in random order instead of memorizing a fixed sequence
Managing your own set of custom question-and-answer cards
Studying quickly with no login required, saved only in your browser
