• Spell checking with live suggestions as you type

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.
