Browser-local capability Tesseract OCR, system TTS, and the browser Translator API can run locally when supported. Larger ASR and translation models are still better suited to Android or Windows.
Privacy boundaries Text, files, OCR frames, and capability settings stay in this browser by default. Remote profiles send translation requests to the selected service. Web Speech network behavior depends on the browser implementation.
