This flashcard maker is a complete, browser-based study tool with two halves: a deck builder where you write the front (question or term) and back (answer or definition) of each card, and a study mode with a card that flips in 3D when you click it. You can add cards one at a time, delete individual entries, clear the whole deck after a confirmation, and navigate with Previous and Next while a counter tracks your position in the deck. A Shuffle button randomizes the order using a Fisher-Yates shuffle, which matters because studying cards in a different order each round prevents you from unknowingly memorizing the sequence rather than the material. Everything runs locally in your browser, so nothing is uploaded.
Flashcards are one of the best-researched study techniques in cognitive science. The simple act of trying to retrieve an answer before revealing it, called active recall or the testing effect, produces dramatically better long-term retention than rereading notes or highlighting text. Shuffled decks also introduce a light form of spaced repetition: cards you keep missing naturally get more attention as you cycle through. Good cards ask one clear question each, so prefer "What year did the Berlin Wall fall?" over a card crammed with three dates. When you are done building, Export Cards downloads your deck as a tab-separated text file you can back up or import elsewhere.
Studying pairs naturally with focused time blocks, so try running your review sessions alongside the Pomodoro Timer for 25 minutes of concentration followed by a short break. If you are studying in a group, the Random Team Generator can split everyone into fair review teams first.
