Coursera dual subtitles and a subtitle translator for every lecture
Coursera brings lectures from universities and companies, mostly in English. Coursera dual subtitles from InterSub show the lecturer's words and their translation together, so every course doubles as Coursera language learning.
How to turn on Coursera dual subtitles
Install InterSub
Add the free InterSub extension to Google Chrome, Microsoft Edge or Firefox. Links for every browser are on the install page.
Choose your languages
Right after installation InterSub asks which language to translate from and which to translate into. Dual subtitles are on by default.
Open a Coursera lecture
Open any Coursera course with subtitles and start a lecture: the second subtitle line appears under the lecturer's subtitles. D on the keyboard turns dual subtitles on or off.
What you get on Coursera
Dual subtitles for university lectures. The language of the course and your native language, one above the other: you keep up with the lecturer and get used to the academic language of your field. If the lecture has subtitles in your language, InterSub shows them as the second line for free. If it has subtitles only in the course language, the AI subtitle translator translates them on the fly; this is a paid feature, included in the free trial.
Second line only on pause. Keep one subtitle line while the lecture plays and see the translation only when you pause: you listen to the lecturer first and check yourself when you need to.
Pop-up dictionary on hover. Hover over any word in the Coursera subtitles: the video pauses and the pop-up dictionary shows the meaning with a context translation, so a new term makes sense before the quiz.
A vocabulary builder from your lectures. Every word you look up is saved to your Wordbook with the line it came from. Over a whole specialization, they add up to a list of your field's terms.
Practice in Anki or our Telegram bot. Sync your Wordbook with Anki on desktop or mobile, or train words in our Telegram bot with an AI tutor and spaced repetition.
Phrases, idioms and phrasal verbs. The AI recognizes English phrasal verbs, idioms and compound nouns in Coursera subtitles and translates the meaning of the whole phrase, not word by word.
Hotkeys, “Show subtitles on pause” for listening practice and other tools work on Coursera too: see all features.
Amazing extension especially for student , all of people need this , thank you
Frequently asked questions
How does InterSub help me learn on Coursera?
Open any Coursera lecture with subtitles and InterSub adds the second line in your language, with a pop-up dictionary on every word. You learn the course content and improve your language at the same time.
What if a Coursera lecture has no subtitles in my language?
Then the AI subtitle translator translates Coursera subtitles into your language on the fly. It is a paid feature: it works during the free 14-day Premium trial, with a promo code and on every paid plan, from the smallest Pay-as-you-go pack of 50 lookups. If a lecture has no subtitles at all, InterSub has nothing to translate.
Does it work for courses taught in other languages?
Yes. InterSub supports dozens of language pairs, such as English to Spanish, Spanish to English, English to Chinese and German to English. You choose the languages when you install InterSub and can change them later in the extension settings.
How much do Coursera dual subtitles cost?
Dual subtitles are free when the lecture has subtitles in both languages. The free plan includes a monthly number of word lookups and starts with a 14-day Premium trial. Translating subtitles with AI is paid: Pay-as-you-go packs start at $1.49, and Premium with unlimited lookups starts at $6 a month. See plans and prices.
