Your flashcard deck lives on this browser alone and is never uploaded. Grab an Export backup before you clear browsing data or study from another device.
Flashcards (Spaced Repetition)
Study a stack of flashcards you build yourself, right in this browser - no sign-in, no app to install.
Mark a card "I knew it" to set it aside for this pass, or "Still learning" to keep it in the queue; Shuffle randomizes the study order.
"Still learning" does not show the same card again right away - it moves to the end of the current queue, so a study pass spreads your weaker cards out instead of repeating one back-to-back.
Cards are saved in this browser via local storage, so they survive a page reload; export a backup (JSON) before clearing browser data or switching devices, since neither is synced automatically.
