The best Language Reactor alternatives

Looking for a Language Reactor alternative? The main reasons people switch are the lack of built-in spaced repetition and the intermediate-plus difficulty. Here are the best alternatives, with LingoBinge as the pick for casual learners and beginners who want saving and review included for free.

Is Language Reactor free?

Partly. Language Reactor has a genuine free tier with dual subtitles and a pop-up dictionary, and a paid Pro tier above it. Its official pricing showed Pro at $5.95 per month or $39.95 per year when we checked on 9 August 2026. That is a dated reading, not a standing quote, so confirm the current price on languagereactor.com before you pay.

Does Language Reactor work with Netflix?

Yes. Language Reactor is a browser extension, so it adds dual subtitles and a pop-up dictionary to the Netflix account you already have rather than to a separate catalogue. It also covers YouTube. LingoBinge works the same way on Netflix, and the difference is what appears on screen: Language Reactor shows both subtitle lines in full, LingoBinge swaps a few words at your level into one line.

Why is Language Reactor not working?

We will not diagnose another team's product, and we have not reproduced a fault in theirs. What we can tell you is what breaks subtitle extensions on Netflix generally, because it has broken ours. Netflix is a single-page app, so moving from Browse into an episode does not always re-inject an extension's content script: reloading the /watch URL directly is the first thing to try. Separately, Netflix only serves the subtitle tracks it holds for a title, so a title with no track in your target language will show nothing whichever extension you use. For anything specific to Language Reactor, their own site is the right place to ask.

Can I move from Language Reactor to LingoBinge?

There is nothing to migrate, and that cuts both ways. LingoBinge cannot import your Language Reactor saved words, so your list starts empty and anything you have built there stays there. Nothing stops you running both, and many people do. Going the other way you are not locked in: LingoBinge exports everything you save as an Anki .apkg or CSV whenever you want. The honest catch is coverage. LingoBinge grades Indonesian today and the other languages are waitlist-gated, so if you are learning one of those, Language Reactor will do more for you right now.
