What Duet Translate is

Duet Translate (懂你翻译) translates what you read and watch without taking the original away. Each paragraph of a page gets its translation underneath, and videos on YouTube, Netflix and X get a second line of subtitles in your language. You read in the language you’re learning and glance down only when you need to.

What it does

• Page translation: translate a whole page in one click, bilingual or translation only, or just the paragraph under your pointer.
• Video subtitles: original and translated subtitles together, in sync with the video.
• Selection translation: select a word or sentence and read its translation and meaning beside it.
• Input translation: write in your own language in any text box and send it in the other one.
• Custom AI actions: your own prompts as buttons, such as a dictionary, a grammar explainer or a polite rewrite.
• Read aloud: hear any selection in a natural voice.

Who does the translating

You choose. Sign in and use the built-in AI with no setup, add an API key from one of more than 20 AI services, run a model on your own computer with Ollama, or use Google and Microsoft’s free translation. See AI providers.
