A free, open-source desktop translation tool for Windows, macOS, and Linux. Select text anywhere, press Ctrl+Q, and the translation appears. No browser tab needed.
What it does
- Translate text from any application — select it and press Ctrl+Q
- Translate in place with Ctrl+Shift+T — replaces your selection
- Screen OCR — draw a rectangle over anything on screen with Ctrl+I, or drag an image / paste from clipboard
- Text to speech — hear selected text with Ctrl+E
- Spell checking with live suggestions as you type
- Summarize or rewrite text in different styles
- Backward translation to spot awkward phrasing
- Translation Rules — auto-select the target language based on detected source language
- Full translation history
- RTL layout support for Arabic, Hebrew, and Farsi
- 15+ themes via FlatLaf, with animated transitions
- Every hotkey is rebindable
Plugins
QTranslate uses a plugin system — translation engines, OCR, TTS, and
spell checkers are all separate .jar files installed at
runtime. When a service breaks or changes its API, you swap the plugin
without reinstalling the app.
The following plugins are included:
- Google — Translator, OCR, TTS, Spell Checker, Dictionary
- Bing — Translator, TTS, Spell Checker
- AI — Translator, Summarizer, Rewriter, Spell Checker (Gemini · GPT · Mistral · Claude)
You can build your own plugin — a minimal translator is about 50 lines of Kotlin.
