PolyCaption

Translate any video to English

Upload a video in any language. PolyCaption detects the language, transcribes it and translates the subtitles into English with the original timing.

How it works

  1. Upload a video in any language.
  2. Click Translate (English is preselected).
  3. Export the video with English captions or download the SRT.

Automatic language detection

You don't need to choose the spoken language. It is detected from the audio.

Translated by sentence

Whole sentences are translated before being split back into timed lines, so the English reads naturally.

Keep the original too

Turn on bilingual captions to show English under the original language.
