Regular subtitles
Regular subtitles show one language
English only — and some words slip by. YouTube auto-translate — and you read your own language while the English passes you by. A word can’t be stopped, saved or reviewed.
Dual subtitles
Dual subtitles on YouTube: English and your language at once
Learn English from shows, interviews and series on YouTube. YabLab shows the English line together with a translation, translates any word on click and turns new words into flashcards, so they stay after the episode ends.
- Chrome extension
- Click-to-translate words
- Words straight into flashcards

YabLab

What fits you
Regular subtitles are enough if…
- You understand almost everything by ear
- You mostly watch Netflix or other streaming services — YabLab doesn’t support them yet
Turn on YabLab dual subtitles if…
- You watch shows, interviews, series or lectures in English on YouTube
- You get the gist but individual words slip by
- You’re tired of pausing to paste words into a translator
- You want words from videos to stick instead of fading

Dual subtitles — questions
How do I turn on dual subtitles on YouTube?
Install the YabLab extension for Chrome and sign in. Open a video with subtitles and YabLab subtitles appear with an English line and a translation. Text size and background are adjustable in their menu.
Does it work on Netflix and other streaming services?
Not yet — YouTube only. For Netflix there is Language Reactor, and you can use it alongside YabLab.
Can I learn English from TV series?
Yes, if the series, its scenes or the show are on YouTube with subtitles. Start with something you have already watched in your language: you know the plot, so your attention stays on the English.
What if a video only has auto-generated subtitles?
That works too. AI adds full stops and capitals, and if YouTube’s translation fails to load, YabLab translates the original itself.
Is it free?
Yes, you can start for free. Pro lifts the limits when you want more.
