Install it, open a video that has captions, and press the CC button — the original stays where it is and a translation appears underneath. Because YouTube hands over the whole caption track at once, the translation is usually ready well ahead of you. Short answer Install the extension, press CC on a video that has captions, and the second language appears underneath. Step by step ## Doing it with NoaLingua - 1 ### Add NoaLingua to Chrome Free, no account, Chrome 138 or newer. - 2 ### Choose the language you are learning, and your own Two dropdowns. Packs begin downloading immediately and in the background. - 3 ### Open a video that has captions and press CC Or the c key. Auto-generated captions count — the extension rebuilds them into whole sentences first. - 4 ### Read both lines, and click anything you do not know One click gives the meaning in that sentence, the dictionary form, the conjugation table and real examples. Save keeps the sentence and the timestamp.

Netflix exposes no such file, so none of those three are possible there — for anybody, not just for us. If you have a choice of platform for study, YouTube is the one that gives a tool more to work with. ### Captions are fragments; sentences are what you want YouTube caption tracks are timed in fragments sized for the screen, not for grammar, so a single sentence is routinely split across three cues and a cue routinely holds the end of one sentence and the start of the next. Translating a fragment produces a translation of a fragment. So the caption blocks are reassembled into whole sentences before anything is translated. That is also what makes replay useful: pressing back lands you at the beginning of a sentence rather than four words into the previous one.

Yes. Auto-generated tracks arrive without punctuation, so a punctuation model restores sentence boundaries before the text is grouped and translated. Quality follows the quality of the underlying transcript. Can I export the whole video as a bilingual document? On YouTube, yes — the entire caption track is available at once, so the full script can be exported with an honest count of what was captured. On Netflix this is impossible for any tool. Does this work on the YouTube mobile app? No. A Chrome extension runs in a desktop browser only. There is no mobile version, and no Firefox or Safari build today. ## Where this is documented on NoaLingua [Dual subtitles on YouTube How captions become sentences, and why it matters.](https://noalingua.com/features/youtube-dual-subtitles/)[Transcript export The whole script of a video, as a file, with an honest count.](https://noalingua.com/features/transcript-export/)[Learning from YouTube without fooling yourself The method, and the trap of comfortable watching.](https://noalingua.com/blog/how-to-learn-a-language-with-youtube/) ### Related NoaLingua answers - [Does Netflix have dual subtitles?](https://noalingua.com/answers/does-netflix-have-dual-subtitles/) - [Can I send Netflix subtitles to Anki?](https://noalingua.com/answers/can-i-send-netflix-subtitles-to-anki/) - [Is YouTube auto-translate the same as dual subtitles?](https://noalingua.com/answers/youtube-auto-translate-vs-dual-subtitles/) ## Try it on the next thing you were going to watch anyway.
