About Dualcue: Dual Subtitle Translator
Dualcue shows two subtitle lines at once on a supported streaming site: the original-language subtitle, and under it a translation into the language you choose, synced to the same cue.
Free to use, with no daily limit.
HOW IT WORKS
- Turn on subtitles in the original language in the site's video player. Dualcue reads that subtitle track and shows it together with a translation line.
- Translation is done on your device by Chrome's built-in Translator API. Subtitle text is not sent to Dualcue servers or to any translation service.
- The first time you use a language pair, Chrome may need to download a translation model. Dualcue shows an "Enable translation" button for this one-time step.
- Pick the target language in the toolbar popup. It starts on your browser's language when Dualcue supports it. You can switch the dual subtitles on or off per tab.
- Subtitle display settings in the popup: show or hide the original line or the translation line, and choose size, position (low, middle, high, plus a slider for fine height) and the color of the translation line.
FREE
- Dualcue is free. There is no daily limit, no account and no license code.
PRIVACY
- No analytics or tracking. After you have used Dualcue a few times, the popup may show an optional link to a short feedback page on our website; it opens only if you click it, and the extension itself sends nothing for it.
- Your viewing history and subtitle text stay on your device.
- Dualcue itself sends nothing to Dualcue servers; it only downloads the site's own subtitle files, to display them.
- When you uninstall Dualcue, your browser opens an optional feedback page on our website; the extension itself sends nothing for it.

REQUIREMENTS AND LIMITS
- The popup is available in English, Korean, Japanese, Spanish, German, French and Brazilian Portuguese and follows your browser language. The optional feedback card is shown in English or Korean only.
- Desktop Chrome 138 or later with the built-in Translator API. If it is not available, or a language pair is not supported, Dualcue shows the original subtitles only.
- Dualcue translates the subtitle text the site provides. It does not transcribe audio, and it has no dictionary, word list, flashcard export, or shadowing tools.
- Works on the compatible site listed below. You need your own subscription to that site and a title that has subtitles.
- The site may change at any time, which can temporarily break the extension.
