Language Reactor
Language Reactor is a language learning toolbox for studying from native content on Netflix, YouTube, books, and websites. Formerly known as Language Learning with Netflix, it helps learners find material at their level and understand it through bilingual subtitles, instant dictionaries, and vocabulary tracking. Over 2 million users rely on it for immersion-style learning without leaving their favorite streaming sites.
A Chrome extension overlays learning tools directly on Netflix and YouTube, adding dual-language subtitles, clickable word definitions, and precise playback controls. The web app adds a curated YouTube and podcast catalog, webpage import for books and articles, and Text-to-Speech for reading along.
Beyond passive watching, PhrasePump drills vocabulary through listening exercises, the Aria chatbot offers conversational practice with corrections, and saved words sync across every feature with smart highlighting for conjugations and plural forms. Learners can export flashcards to Anki with screenshots and audio clips.
Built for learners at any level across 40+ languages, Language Reactor suits students, polyglots, and casual viewers who already watch foreign media and want structure around that habit.
