Mac
Awnsy is a small menu bar translator for macOS. Select text in any app, press ⌘C twice, and the translation appears right over the window. For text you can't select, like images, scanned PDFs or video, drag a box around it and Awnsy reads and translates it. The translation model lives inside the app and runs on your Mac. No account, no API key, works offline, and what you translate stays on your machine. If you prefer cloud quality, add your own OpenAI or Anthropic key.

Built end to end with AI agents in Claude Code. 13 languages, works offline. No streaks, no tests, no XP.
