Language Reactor alternative for YouTube

Language Reactor is a well known tool for learning languages with video. If you are looking for another option for YouTube, this page tells you what Dual Subtitles does, and where it is different. We are the makers of Dual Subtitles, so read this with that in mind. We tried to be fair.

What both do

Both show subtitles in two languages on a YouTube video. Both give you a way to look up words while you watch. Both are made for people who learn languages by watching real videos.

Where Dual Subtitles is different

• YouTube only. Dual Subtitles works on YouTube, including Shorts, theater mode, fullscreen and embedded videos. It does not work on Netflix or other streaming sites. Language Reactor works on more than YouTube. If you want one tool for Netflix too, that matters.
• Sentence alignment. Automatic captions are cut in odd pieces. Dual Subtitles joins them into whole sentences and matches the translation to the same sentence.
• On-device word lookup. When you click a word, the translation runs in your browser with Chrome's built-in Translator, so the text stays on your computer.
• Word book and Anki. You can save words with their sentence and the time in the video, then export an Anki file or CSV. Export is free.
• Downloads. Dual-language SRT, original-only SRT, translation-only SRT, dual WebVTT and TXT.
• Practice tools. Loop a line, slow the video to 0.75x or 0.5x, hide a line until you hover, and a dictation mode.
• Explain in context (Pro). The meaning of a word in this exact line, including phrases and idioms. Free accounts get 5 a day. Pro is $4.99 a month, $29.99 a year, or $79 once, with a 7 day free trial. Everything else above is free.

Who should choose which

Choose Dual Subtitles if you mostly learn from YouTube, want a free tool with no account for the core features, and want your data to stay in the browser.

Choose Language Reactor, or another tool, if you need Netflix or other sites, or if you prefer its way of working. Check its current features and prices on its own site, because they change.

You can also install both and see which one fits your habit. They are extensions, so trying costs little.

A note on this page
