Den: Learn Languages with AI — Save Words from Subtitles

Select a word in Netflix, YouTube or Disney+ subtitles or on any site; AI explains it in context, then save and review.

🎬 Watch, select, learn. With Den, learning a language becomes part of your daily life. Den lets you select any word you don't know — in Netflix, YouTube, Disney+, HBO Max and Prime Video subtitles, or on any website — and learn it instantly with AI. It shows the word's REAL meaning in that exact sentence (not just a dictionary entry), recognizes idioms and fixed expressions, generates example sentences, and saves the word to your personal vocabulary. ▶ HOW IT WORKS 1. Select a word or phrase while watching a video or browsing any page. 2. Den analyzes it in context with AI: meaning, part of speech, whether it's an idiom, and examples. 3. Save it with one tap and make it stick with spaced repetition in the Den mobile app. ✨ FEATURES • Meaning in context — AI figures out what the word means in that sentence, not a flat dictionary translation. • Streaming subtitle integration — Click words directly in Netflix, YouTube, Disney+, HBO Max and Prime Video subtitles. • Works on every site — News, blogs, articles, dictionaries… select and learn anywhere. • Idiom & phrase detection — Explains expressions like "kick the bucket" by their real meaning, not word by word. • Personal vocabulary — Every word you save syncs with your account. • Spaced repetition (SRS) — Review words at the right time so you never forget them. • Multiple target languages — English, German, Spanish, French, Italian and more.
