Six months into learning Japanese well enough to handle vendor emails, I noticed I'd translated the same polite refusal phrase four times without retaining it once. Google Translate gave me one answer, I pasted it in, moved on. Nothing stuck.
The problem isn't the translation itself — it's that a single output teaches you nothing about why that phrasing works, what register you're operating in, or what a more casual version would sound like if you were writing to someone you actually knew.
So I built konid as an MCP server. Every query returns three options ordered casual to formal, with the register explained and a cultural context note comparing them. For that refusal phrase, I got the stiff keigo version appropriate for a new vendor, a warmer alternative for someone I'd worked with for months, and a note on why mixing the two registers in the same email would read as odd to a native speaker.
Over enough work emails, that becomes a real learning loop instead of a copy-paste utility.
