A translator for Windows. Select text in any app and press CtrlCC.

Japanese text gets furigana, Yomitan lookups and notes on idioms, tone and politeness. Other languages translate without them. The Files tab translates subtitles, text files, PDFs and pictures.

Accounts

An ocu account lets the app translate without your own API key. It’s free and unlimited within fair use. Accounts are invite only, and invites come from me.

Fair use
