壹If it can handle keigo, it can handle anything.

Tailor your words.

How many minutes a day do you spend rewriting business chats — tone, register, exact phrasing? Shitate reads the context and the recipient, then rewrites the draft for you in 10 seconds. The more you use it, the more it sounds like you. For individuals and teams.

問問 ─ Problem

Have you ever sent messages like these?

01
「Hey, about that thing yesterday...」
⚠Too vague for a senior client. Reads as careless.
02
「Got it!」
⚠The recipient is a board member. Risky.
03
「No can do」
⚠Too casual. No reason given. Cold.
