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. ■ Made for real-life Japanese communication ・Write appropriate messages to managers, professors, clients, and coworkers ・Turn textbook Japanese into wording that sounds more natural ・Soften messages that may come across as cold or too direct ・Create polished Japanese emails without memorizing business expressions ・Translate English into natural Japanese that fits the situation ・Generate a reply when you are unsure what to say next ■ Key features ◎ Rewrite Japanese in one tap Transform your text into polite Japanese, business Japanese, casual language, clearer wording, and more.
