” Could you for testing purposes please get a free DeepL API key and see if the translation quality is much improved? It could very well be that it is the OCR and not the translations that are at fault, most of the time. “
I have tested DeepL API translation. And while it is indeed better, the additional time each translation takes - roughly 2x longer than local - is just not worth it. I’m lucky enough to be bilingual so the tool is only there to support/correct my live translations. But this makes speed paramount.
