Udemy dual subtitles and a subtitle translator for every course
Most Udemy courses are taught in English, and many others in Spanish, Portuguese and other languages. Udemy dual subtitles from InterSub put the instructor's words and their translation on screen together, so you learn the skill and the language in the same lesson.
How to get dual subtitles on Udemy
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 Udemy lecture
Open any Udemy course with subtitles and start a lecture: the second subtitle line appears under the instructor's subtitles. D on the keyboard turns dual subtitles on or off.
What you get on Udemy
Dual subtitles for every lecture. The language of the course and your native language, one above the other: you follow the instructor without rewinding. 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. Confident in the course language? Keep one subtitle line while the lecture plays and see the translation only when you pause, so it doesn't distract you.
Pop-up dictionary on hover. Hover over any word in the Udemy subtitles: the video pauses and the pop-up dictionary shows the meaning with a context translation, so you see what a technical term means in this lecture.
A vocabulary builder from your courses. Every word you look up is saved to your Wordbook with the line it came from: the terms you actually need at work.
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 Udemy 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 Udemy too: see all features.
This function is really helpful! Translation to French seems pretty accurate. It’s great that there is no need to interrupt watching if you didn't understand a new word.
Frequently asked questions
How does InterSub help me learn on Udemy?
Open any Udemy course 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 Udemy course has no subtitles in my language?
Then the AI subtitle translator translates the course 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 Spanish, Portuguese or other languages?
Yes. InterSub supports dozens of language pairs, such as English to Spanish, Spanish to English, English to Japanese and German to English. You choose the languages when you install InterSub and can change them later in the extension settings.
How much do Udemy 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.
Which browsers can I use?
