About Language Reactor
What is Language Reactor (2026 update)
Language Reactor is a language learning toolbox in the chatbot and virtual assistant category, built as a browser extension and web app that overlays dual subtitles, dictionary lookups, and AI tools on Netflix, YouTube, books, and websites. It targets people who want to learn a language by watching real shows and videos instead of working through a traditional course.
What is new in 2026
The core of Language Reactor’s 2026 offering is still dual subtitles and click-to-translate vocabulary tools, but the platform has added an AI conversation layer called Aria, an AI language partner used for instant corrections and conversation practice, alongside its existing PhrasePump spaced-repetition tool and Lexa AI dictionary for Pro subscribers. One notable 2026 status change is that the Chrome extension was reported unavailable for direct installation from the Chrome Web Store as of February 2026, though the main website remained active and continued to promote the tool, so anyone installing it should check the current install path on the official site rather than assuming the extension listing is live.
Key features
- Dual subtitles showing the target language and native language at the same time, with customizable font, size, color, and background
- Click-to-translate dictionary lookups for unfamiliar words while watching
- PhrasePump spaced-repetition engine for vocabulary review
- Anki export for learners who study with external spaced-repetition apps
- Aria, an AI language partner for conversation practice and corrections
- Lexa AI dictionary for deeper word and phrase analysis
- CEFR-graded video catalog to match content to a learner’s level
Pricing in 2026
Language Reactor runs a simple two-tier model: a free plan and one paid Pro plan, with no separate mid tier. Third-party sources report different exact Pro rates in 2026, ranging from about $4.99 to $5.95 per month depending on the source and billing period, with yearly plans discounted well below the monthly rate. Because these figures do not agree, check the official site for the exact current price before subscribing.
| Plan | Price | What you get |
|---|---|---|
| Free | Free | Dual subtitles, click-to-translate, limited vocabulary saves, access restricted to popular languages such as Spanish, French, German, and Portuguese |
| Pro | Roughly $5/month, billed monthly or yearly at a discount (check official site for exact current rate) | All 30+ supported languages, unlimited vocabulary saves, offline mode, PhrasePump spaced repetition, Anki export, and the Lexa AI dictionary |
Who should use it
Language Reactor fits self-directed learners who already watch Netflix or YouTube in a target language and want dual subtitles, click-to-translate, and spaced-repetition review built into that habit, rather than a separate app or classroom course. It is a strong fit for intermediate to advanced learners doing immersion-style study with real native content. It is a weaker fit for complete beginners who need structured grammar lessons, since Language Reactor assumes you already have source material you want to study from.
Limitations and alternatives
The free plan restricts access to a handful of popular languages and caps vocabulary saves, so serious learners of less common languages will likely need Pro. The Chrome extension’s uncertain listing status in 2026 is worth checking before you rely on it for daily use. For a comparable dual-subtitle and AI conversation approach, learners commonly compare Language Reactor against Trancy and Lingopie, both of which also overlay subtitle and vocabulary tools on streaming video, and against Lexirise for a more app-based alternative. Anyone weighing Pro against these alternatives should compare the exact current price and supported language list on each provider’s own site, since all of them update pricing and language coverage periodically.
