Free Flashcard Maker & Ready-Made Study Decks
Flashcards are one of the most effective ways to learn because they force active recall: you try to remember the answer before you flip the card. This free flashcard maker lets you build your own decks or study from ready-made decks on popular topics, with no signup.
Every ready-made deck has its own page, so you can bookmark it, share the link with classmates or find it in search. Study a deck start to finish, shuffle the cards, and repeat the ones you miss until they stick.
Active recall
Testing yourself beats rereading notes. Flip, answer, check, repeat.
Spaced repetition
Revisit hard cards more often and easy cards less often to remember more in less time.
Your own decks
Create cards for any subject: vocabulary, formulas, dates, definitions or code.
Study anywhere
Works on phones and tablets, so you can review on the bus or between classes.
