Knowch Keyboard

One keyboard for Korean, Japanese and English — with Hangul-to-Japanese input.

The keyboard that moves with your languages.

Knowch Keyboard brings Korean, Japanese and English together in one Android keyboard. Choose the layout you know, arrange input modes your way, and keep writing without switching between keyboard apps.

WRITE IN KOREAN, JAPANESE AND ENGLISH
Use Korean QWERTY, Cheonjiin or Naratgeul; Japanese 12-key flick or QWERTY; and English QWERTY. Switch modes quickly and keep the layouts you use most within reach.

HANGUL PRONUNCIATION TO JAPANESE
Its signature feature: type Japanese sounds in Hangul, then choose the Japanese word you want. Write “아리가토” and select “ありがとう”; write “칸코쿠” and select “韓国”. It is a practical new way to write Japanese for Hangul users.

JAPANESE YOUR WAY
Use Hiragana, Katakana and conversion candidates directly when you need them. Familiar Japanese input remains available even when you do not use Hangul pronunciation.

MAKE IT YOURS
Choose number rows, keyboard height, haptic feedback, clipboard history, display language and themes. The basic light theme is included; additional themes can be downloaded from the app.

PRIVATE BY DESIGN
Key input, basic conversion and candidate learning are processed on your device. Your typed text and passwords are not sent to our servers. Suggestions and learning are disabled in password fields.

30-DAY FREE TRIAL
Try Hangul-pronunciation Japanese input free for 30 days. Afterwards, unlock it once through Google Play—no subscription required. Korean, Japanese and English keyboard features remain available.

For people who move between Korean, Japanese and English every day: learners, travelers, fans, creators and multilingual communicators.
