DeepL Translator vs. Free Online Translators
Unlike free online translators, DeepL Pro makes a clear commitment: we will not use your text to train AI models, will not use your data for any non-translation purposes, and will not store your translations longer than necessary to complete the translation. This is why global financial institutions, law firms, and pharmaceutical companies trust DeepL.
