DeepL
Translates web pages, selected text and what you type into other languages, and helps polish your writing as you go.
Chrome extension
Translates selected text or whole pages on your device, shows dual-language YouTube subtitles and explains words in context for language learners.
Wordy translates selected text or full pages on your own device and shows bilingual subtitles on YouTube. A contextual dictionary explains words where they appear, which suits language learners.
Select text to translate it or switch on page translation; on YouTube, turn on bilingual subtitles from the extension.
Language support is limited to the languages the extension lists. On-device translation keeps text local but may be less detailed than cloud services.
