Made by students, for students — free AI-powered flashcards with no ads. CardJet turns your word lists into flashcards that actually stick. Paste a list, import from Anki or a spreadsheet, or let Cat build a set from your notes — then study with six modes that adapt to whatever you keep forgetting. STUDY YOUR WAY • Flashcards — flip, browse, star the hard ones • Learn — multiple choice that turns into typing as you improve • Write — type the answer, with forgiving checking for accents and synonyms • Test — a mixed quiz you can retake as often as you like • Match — race to pair terms with their meanings • Spell — hear the word, type what you heard REVIEWS TIMED BY SCIENCE CardJet schedules every card with FSRS, the modern spaced-repetition algorithm. You see a word right before you would have forgotten it — not sooner, not later. Nothing to configure. CAT, YOUR STUDY HELPER Ask Cat for usage examples in the language you are learning, the difference between two expressions that look alike, or why a spelling went wrong. Examples come in your target language; explanations come in yours. PICTURES IN ONE TAP Illustrate a whole set at once from open-license image search, or add your own photos. WORKS OFFLINE Everything lives on your device and syncs to your account once you are back online. You do not need an account to start — guest mode has every study feature. SEVEN LANGUAGES English, Русский, Español, 中文, 日本語, 한국어, Tagalog. No ads. No subscription required.
