Open flashcard dataset

The EverFlip Multilingual Flashcard Corpus is a free, CC-BY-4.0 open dataset: 24,164 flashcards across 81 languages, organised into 1,573 themed decks and exam ladders (JLPT, HSK, TOPIK, DELE/DELF/ Goethe/CILS/CAPLE). Each card is a factual lexical correspondence — a word or phrase, its reading where the script is non-Latin, and its English meaning. Use it freely with attribution.
