Flashcards
Create decks, flip cards, and repeat the ones you miss — saved on your device.
How it works
-
Create a deck and give it a name.
-
Add cards with a question on the front and the answer on the back.
-
Study: tap a card to flip it, then mark "Knew it" or "Again".
-
Cards marked "Again" come back until you know the whole deck.
Frequently asked questions
Where are my decks stored?
In your browser's local storage on this device. They never leave your device — but that also means clearing browser data deletes them, so export important decks as JSON backups.
Can I move decks to another device?
Yes. Export a deck as a JSON file, send it to yourself, and import it on the other device — the deck arrives with all its cards.
What does "Again" do exactly?
It sends the card to the back of the study queue, so it reappears in the same session until you mark it "Knew it". That spaced repetition is what makes flashcards stick.
Is anything uploaded to a server?
No. Decks, cards, and study progress all stay in your browser — nothing is uploaded, ever.
