ScreenTranslate

The tool lets macOS users translate visible text without leaving the current application. Users can either draw a rectangle around any screen region or highlight existing text, then press a shortcut to trigger OCR (for captured regions) or direct translation (for selected text). The result appears in a brief popup near the source, and each translation is automatically stored in a history accessible from the menu bar.

All processing runs on the local machine using Apple’s on‑device translation engine, so no data is sent to external servers and the application works offline after language packs are downloaded. It supports a set of languages including Korean, English, Japanese, Chinese (both simplified and traditional), French, German, Spanish, Portuguese, Italian, Russian, Arabic, Dutch, Hindi, Indonesian, Polish, Thai, Turkish, Ukrainian, and Vietnamese, with auto‑detection of the source language.

The lightweight menu‑bar app is free, open‑source, and compatible with macOS 15+ on both Apple Silicon and Intel hardware. It provides a persistent translation history, quick access via keyboard shortcuts, and operates without requiring an account or internet connection.
