Den: Learn Languages with AI — Save Words from Subtitles

About

🎬 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.
