Fixu

Your Japanese keyboard with instant grammar and tone feedback - right as you type, in any app.

Fixu is the Japanese keyboard that checks your grammar and tone before you send, so you can write with confidence in every conversation.

Whether you're texting friends, emailing colleagues, or posting on social media, Fixu gives you real-time feedback right inside your keyboard. No switching apps. No copy-pasting into ChatGPT. Just you, writing in Japanese on your own.

HOW IT WORKS Install Fixu as your keyboard and write in Japanese like normal. When you're ready, request feedback - Fixu analyzes your grammar and tone and surfaces corrections instantly. Accept a suggestion with one tap.

FEATURES • Grammar corrections — catch mistakes before anyone else does • Tone feedback — know if your message sounds natural, too casual, or too formal • 12-key flick (12キー) and QWERTY Japanese input modes • Works in every app — Messages, Line, email, anything • Sign in once, use everywhere
