Show HN: ScreenTranslate – On-device screen translator for macOS (open source)
hcmhcs0 Friday, March 06, 2026
I kept breaking my workflow to translate foreign text — copy, open browser, paste into translator, read, switch back. Repeat.
So I built a macOS menu bar app that translates right where you're working.
Two modes:
- Select text in any app → Cmd+Option+Z → instant translation
- Cmd+Shift+T → drag over any area → OCR + translate (images, PDFs, subtitles)
Everything runs on-device via Apple Vision + Apple Translation. No servers, no tracking. Free
forever.
