Tatsu – Offline Kanji

Offline kanji dictionary. Search by English, kana or romaji. No account, no ads.

Tatsu is a kanji dictionary that works entirely offline. Type a word, get the kanji. There is no account, no network access and no tracking.

Search in English, hiragana, katakana or romaji, or paste a sentence of kanji to see each character in order. Small typos are forgiven, and results are ranked by how often the kanji is used, so common characters come first.

Open a kanji to see its on and kun readings with kana and romaji, its meanings, name readings, stroke count, school grade, JLPT level and frequency rank. Copy a kanji with one tap. Kanji you open or copy are listed under Recent, stored only on your device. You can remove items or clear the list at any time.

Tatsu covers about 10,300 kanji from KANJIDIC2.
