About Kotomi - Your Japanese Deck
Kotomi is a place to build your own Japanese dictionary from the words you actually read. Instead of grinding through someone else's word list, you collect your own. Come across a new word? Add it, and Kotomi finds the reading (with romaji), the meaning, and a simple breakdown of each kanji from a dictionary built into the app. Then it helps you remember it with spaced-repetition quizzes. WHAT YOU CAN DO • Build your own word lists from what you read • Look up readings and meanings — no internet needed • See a clear kanji breakdown for every word • Handle homophones: pick the exact word you meant (e.g. まつ, いる) • Review with spaced repetition in four modes: Meaning, Reading, Writing, and Mixed • Tap to hear how a word is pronounced • Keep a word of the day on your home screen with widgets YOURS, AND PRIVATE • Your dictionary and progress stay on your device • Works fully offline • No account, no ads, no tracking Kotomi is an early, independent project from a hobby developer who is also learning Japanese. The built-in dictionary uses data from the open JMdict and KANJIDIC2 projects (under CC BY-SA 4.0); attribution is shown in the app under "Data sources & licenses".
