Vocabden: Learn English or German from YouTube & Netflix Subtitles with AI

🎬 Learn English or German from the shows you already watch. Vocabden helps you learn English or German from the subtitles of the series, films and videos you watch. Click a subtitle word to see its meaning in that sentence, explained by AI. Save the word and review it later with flashcards inside the extension. ▶ HOW IT WORKS 1. Sign in with Google, Apple or a link sent to your email. An account is required for AI explanations because they run on Vocabden's servers. 2. Click a word while you watch. Select it and tap the button that appears, Alt/Option-click it, or press Alt+V. Prefer double-click? Switch it on in Settings. 3. Read it, save it, review it. The toolbar badge counts how many words are ready, and the review session opens from the same icon. ✨ WHAT YOU GET • The meaning that was actually said. "Charge" in a courtroom and "charge" on a phone are not the same word, and the sentence decides which one you get. • Idioms explained whole. "A blessing in disguise" is recognized as a fixed expression and explained by what it really means, not word by word. • Example sentences, plus the word itself read aloud so you know how it sounds. • The whole line, when one word is not the problem. Ask for it and the full subtitle line gets translated. • A second line, only on YouTube. When the video already has captions in your language, Vocabden can show them under the original automatically — the platform's own translation, not AI. • Spaced repetition without leaving your browser. Saved words return as review cards at widening intervals, and the toolbar badge tells you how many are due. • YouTube transcripts too. The transcript panel works the way subtitles do, with clean sentence context around every word, which helps on talks, interviews and lessons. • An interface in 15 languages, so the explanation reaches you in a language you already think in. • Optional highlighting of words you have already saved, on the sites where you have allowed Vocabden to run. Off until you switch it on. • Saved words sync with the Vocabden mobile app. There, watch English videos in Clips and practise conversations with Den in Role Play. 🔒 PERMISSIONS — WE ASK FOR LESS At install, Vocabden asks to read subtitles on the five streaming services it supports — Netflix, YouTube, Disney+, HBO Max and Prime Video — and to reach its own server at api.denapp.xyz. That is the list. It does not read the content of any other website. Want it on news sites, blogs and articles as well? That is a separate, optional permission you grant yourself, from the welcome screen or later in Settings, and the same switch takes it back. When you analyze a word, that word and the sentence it appeared in go to Vocabden's servers so the AI can read them. Your browsing history does not. 💡 FREE AND PRO You can use Vocabden for free with a limited AI analysis allowance. Paid plans provide higher allowances; check the mobile app for current plans and prices. The extension shows your most recently saved words for quick review; your full collection stays in your account. 🎯 WHO IT'S FOR People who would rather learn from an episode than from a textbook: students, exam candidates, and anyone who has looked up the same word five times and still does not own it. If you have used a pop-up dictionary before, this is the part that was missing — the explanation fits the scene, and the word keeps coming back until it sticks. Install it, open a video with subtitles, and click the first word you do not know. More at vocabden.com
