Dual Subtitles: Learn Languages with Movies

Dual Subtitles helps you learn languages while watching films, series, and videos. It shows two subtitle lines at the same time: the original line and a translation underneath. You can click any word to translate it, then save useful words to your vocabulary with the sentence where you found them. The extension can also search for available online subtitles for the current movie or episode and load them into the player. This is useful when the website has no suitable subtitle track, when subtitles are missing in your language, or when you want to use a different subtitle source. Works on selected video websites, currently including Netflix, Amazon Prime Video, Kino.pub, YouTube, and HDRezka. Main features: Dual subtitles See the original subtitle line and a translated line together while watching.
