Study languages with the subtitles already playing in your browser. Couchlingo turns the videos you already watch into language lessons. Watch Netflix or YouTube as usual. Couchlingo shows the original subtitle and its translation together, lets you click any word to see what it means, and keeps a synced transcript of the whole episode next to the player. WHAT YOU GET • Dual subtitles: the original line with its translation right underneath • Click any word: instant definition, with its meaning in context • Synced transcript: scroll through the episode and click a line to jump back to it • Save words and phrases, with the sentence and the show they came from • Study controls: replay a line, auto-pause after each line, slow playback down • Your vocabulary everywhere: saved words sync to your account on couchlingo.com WORKS WITH Netflix and YouTube, using the subtitles the video already has: French, Spanish, German, Italian, Japanese, Korean and more. HOW IT WORKS 1. Install Couchlingo. 2. Create your account on couchlingo.com. The extension links to it automatically. 3. Open a video with subtitles and start learning. Dual subtitles, the transcript and word lookups are part of the Couchlingo subscription, available on couchlingo.com. PRIVACY Couchlingo only runs on Netflix, YouTube and couchlingo.com. It reads the subtitles your browser has already loaded; it never records your screen or audio, and we never sell your data. Privacy policy: https://couchlingo.com/privacy Couchlingo is not affiliated with, endorsed by or sponsored by Netflix or YouTube.
