NihonGoAIR: Learn Japanese

ホットドッグ or ホットドック? Katakana Lens turns the loanwords you only thought you knew into the ones you can actually spell.

Learn Japanese from the world around you.

Point your camera at a chair, a bowl, a vending machine — NihonGoAIR names it in Japanese and drops the word straight into your review deck. Detection runs entirely on your device, so it works on the train, in a queue, and in aeroplane mode.

NEW — KATAKANA LENS

You know what ホットドッグ means. Can you spell it? Most learners can't, because loanwords feel familiar right up until you have to write one. Katakana Lens shows you four spellings and asks for the right one, then highlights the exact character that was wrong — a missing long vowel, a small ッ, a stray dakuten. Point the camera at something, or just work through the list.
