Hibikey

Translate without friction. Write without switching.

Hibikey is an AI translation and writing keyboard for people who message across languages. If you’re tired of bouncing between apps, copy-pasting into translators, and explaining what you want over and over, Hibikey keeps you in flow. Everything happens where you already type.
Hibikey turns your intent into send-ready text in seconds.
Why Hibikey feels different
Most “AI writing” tools still create a context switch: leave the conversation, paste text into a tool, prompt it, then paste the result back. Hibikey lives inside your keyboard, so translating and polishing becomes a quick step in the same motion as typing.
