敬語ボタン｜AI変換・返信キーボード

Writing Japanese is one thing. Sounding right is another.

A message can be grammatically correct and still feel too blunt, too casual, or strangely formal. 敬語ボタン helps you find the right tone without leaving the app you are using.

Type normally in LINE, email, Slack, Instagram, or any other app, then tap an AI button to make your Japanese more polite, natural, concise, friendly, or professional.

No copying everything into ChatGPT. No rewriting the same sentence five times. Just type, tap, and send with confidence.
