EverFlip Multilingual Flashcard Corpus

An open flashcard corpus from EverFlip (everflip.app): 24,164 cards 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 in the target language, its reading (for non-Latin scripts), and its English meaning. Released under CC-BY-4.0; only the factual card data is included (not the app, scheduling, or editorial prose). Files: cards.csv (24,164 rows), decks.csv (1,573), languages.csv (81), datapackage.json (frictionlessdata.io descriptor). Use the meaning_en column for the normalized English meaning.
