Language Reactor Alternatives: 6 Tools Compared (2026)
The main Language Reactor alternatives are Migaku, Lingopie, Trancy, asbplayer, Readlang and JoJoJi. None of them is a straight replacement: each one beats Language Reactor on one point (built-in flashcards, a phone app, its own catalogue, shadowing) and gives something up elsewhere. Before switching, it is worth knowing that Language Reactor's free version already does a lot.
JoJoJi is one of the tools on this list, so this page is built on what each product states on its own site, checked in November 2026. Prices are dated and linked so you can verify them. Ours is the one to look at if what you miss in Language Reactor is speaking: on YouTube, JoJoJi replays every line so you say it with the speaker, and keeps your words as flashcards without Anki.
What Language Reactor does, and what is free
Language Reactor, formerly Language Learning with Netflix, is a Chrome extension for Netflix and YouTube, with a companion website for books, web pages and practice tools. Its site lists:
- bilingual subtitles, with transliteration for languages that use another script
- a pop-up dictionary with example sentences
- playback controls: speed, keyboard shortcuts, and auto-pause after each subtitle
- content in more than 40 languages
- PhrasePump, a listening exercise built around your saved words
- a chatbot called Aria, and export to Anki
Its website can be opened in a phone or tablet browser, but the extension itself, and with it the Netflix and YouTube features, only runs in Chrome on a computer. There is no dedicated app.
Is Language Reactor free?
Mostly, yes. The site calls Pro mode "optional" and the free version covers dual subtitles, the dictionary and the playback controls. According to its Pro page and FAQ, Pro adds:
- machine translation, plus speech recognition for Netflix audio tracks (useful for dubbed shows)
- saving words and phrases across all features, with highlighting and export to Anki (the free version saves words inside PhrasePump only)
- a stronger AI dictionary model and memory for the chatbot
Pro is cheap. When we checked from Europe in November 2026, the page showed €5.47 for one month, €12.83 for three months and €36.73 for a year. The page shows the price in your own currency once you are there.
How to use Language Reactor
- Install the extension from the Chrome Web Store, using the link on languagereactor.com.
- Open a video on YouTube or a title on Netflix. A Language Reactor button appears in the player; the same button switches the extension off.
- Pick your study language and your translation language in its settings.
- Click a word for the dictionary, and turn on auto-pause if you want the video to stop after each subtitle.
Our guide to dual subtitles on YouTube covers the subtitle side in more detail.
Why look for an alternative
Common reasons, all of which follow from the feature list above:
- You want to practise speaking, not only understand.
- You want flashcards with spaced repetition built in, without exporting to Anki.
- You want a real phone app.
- You watch Disney+ or another service. Language Reactor's FAQ says it does not support Disney+ or Amazon Prime yet.
- You would rather have content chosen for you.

Migaku
The most complete paid option.

It supports 11 languages.
It has no free plan: Standard is $10 a month, Early Access $15, Lifetime $499, with a 10-day money-back guarantee. Details are in our Migaku review.
Migaku vs Language Reactor: pick Migaku for an all-in-one system with phone apps; stay with Language Reactor if free subtitles and a dictionary are enough, or if your language is not among Migaku's 11.
Lingopie
Lingopie is a different kind of product: a streaming platform with its own shows, films and other content in 15 languages, with dual subtitles, clickable words that become flashcards, and what its site calls an AI-powered pronunciation coach. It runs on phones, tablets, computers and TVs, with apps for iOS, Android, Fire TV, Roku and Google TV. A Chrome extension for Netflix and Disney+ is included in the subscription.
Plans are a three-month plan for one language, a yearly plan and a lifetime plan for all languages, with a 7-day free trial. Lingopie runs frequent promotions, so read the current figures on its pricing page.
Lingopie vs Language Reactor: Lingopie if you want a ready-made catalogue and TV or phone apps; Language Reactor if you want to study what you already watch on YouTube and Netflix, at no cost.
Trancy
Trancy is the closest to Language Reactor in shape, with broader reach. Its free plan includes bilingual subtitles on YouTube, Netflix, HBO, Disney+, TED, Coursera, Udemy and others, unlimited word and sentence translation, and full-page web translation. It offers extensions for Chrome, Edge, Firefox and Safari, including mobile browsers.
The free plan caps saved items at 100 words and 50 sentences. Premium removes the caps and adds AI features, including AI shadowing training and AI Talk speaking practice. It was listed at $3.49 a month in November 2026, with a 3-day free trial and a cheaper yearly rate.
asbplayer
asbplayer is a free, open-source browser extension and web player for sentence mining. It loads subtitles onto most streaming video, can auto-pause at each subtitle and repeat a subtitle a set number of times, and creates Anki cards with audio and image through AnkiConnect.
You assemble the rest yourself: Anki, a dictionary tool such as Yomitan, sometimes your own subtitle files. It suits learners who already use Anki and enjoy configuring things.
Readlang
Readlang is a reader first: click a word or phrase on a web page, in an uploaded text or in a supported video to translate it, and every lookup becomes a flashcard. The free plan gives unlimited single-word translations and 10 phrase translations a day; Premium is $6 a month or $48 a year. It is the right alternative if your study is mostly reading.
JoJoJi: the alternative that gets you speaking
Language Reactor makes a video understandable. JoJoJi, a Chrome extension for YouTube on a computer, is built for the next step: saying it and remembering it.
- You speak with the native speaker. Shadow mode plays a line, stops, then plays it again, slower the first time if you like, so you say it at the same moment. No rewinding by hand.
- Your words become flashcards with no work. Click a word in the subtitles for its meaning; one button keeps it with the sentence it came from. No export, no Anki, no deck to build.
- Reviews are ready when you are. Spaced repetition on jojoji.app, with no settings.
Dual subtitles, a transcript beside the video and pronunciation above the words come with it.
It is the narrowest tool here, on purpose. No Netflix, no phone app, no Anki export, no recording or scoring of your voice, and no free plan or trial: it costs $9.99 a month or $29.99 a year. If you watch Netflix, want something free, or study on your phone, another tool on this page will serve you better. If YouTube plus speaking practice plus simple reviews is the routine you want, start with JoJoJi.
