Aim the reticle
Place the center guide over horizontal or vertical Japanese text and let on-device recognition find nearby terms.
Printed Japanese, readable in the moment
Point your camera at kanji. See the reading before the page gets cold.
KanjiLens gives Japanese learners camera-based kanji detection, furigana-style hiragana readings, and quick offline definitions for books, handouts, signs, and dense printed passages.
