Watch YouTube with two subtitles at the same time. The original is on top and the translation is right below it. Learn a language by watching what you love.
What you get
- Original and translation at once. Both lines sit on the video and stay in sync.
- Works with every kind of track: subtitles uploaded by the creator, automatic captions, and YouTube's own auto-translate.
- Sentence alignment. Automatic captions are cut in odd pieces. Dual Subtitles joins them into whole sentences and matches the translation to the same sentence.
- Transcript panel. See every line in both languages next to the video. Click a line to jump there. Search the text. Choose the original and the translation language from a list.
- Click a word to see its meaning. The translation runs on your device with Chrome's built-in Translator, so the text does not leave your computer. For English words there is a fallback that shows definitions from Wiktionary.
- Word book. Save words with their sentence and the time in the video. Export them as an Anki file or CSV.
- Download subtitles. Dual-language SRT, original-only SRT, translation-only SRT, dual WebVTT, and TXT.
- Practice tools. Loop the current line. Slow the video down to 0.75x or 0.5x. Hide the original or the translation until you hover over the lines.
- Make it yours. Ready-made styles plus full control of font, size, weight, color, background and outline for each line. Drag the lines anywhere on the player. Live preview in the settings.
- Keyboard shortcuts. Turn subtitles on or off, show or hide the translation, go to the previous or next line, repeat a line, open the panel. You can change every key.
- Works on regular videos, Shorts, theater mode, fullscreen, the mini player, and embedded YouTube videos on other sites.
- 14 interface languages.
How it works
Open a video on YouTube. Dual Subtitles reads the subtitle track the video already has and shows it with a second track in your language. Pick the languages in the popup or in the panel. Your choice is remembered for each video.
