  FluentHub adds dual subtitles (learning language + your language), AI-powered translations, and tap-to-learn vocabulary on the same screen as the video. Understand dialogue faster and remember words from the shows you already love.

  1. Install FluentHub and open a YouTube or Netflix video.
  2. Turn on dual subtitles and pick your learning + translation languages.
  3. Tap any word in the subtitles for instant translation, collocations, and AI context.
  
  FEATURES
  • Dual subtitles on YouTube and Netflix
  • AI subtitle translation (smarter than basic auto-translate)
  • Tap or hover words for definitions, usage, grammar notes, and examples
  • Transcript panel: read along, frequent words, and keywords synced to playback
  • Collocations and phrase-level help tied to the current line
  • Multi-word selection for phrases and expressions
  • CEFR-style level settings and word familiarity tracking
  • Shadowing practice: replay lines, record yourself, and compare pronunciation
  • Light and dark theme
  
  WHO IT'S FOR
  Self-directed learners who learn best from real videos—not textbooks. If you use Language Reactor or similar tools, FluentHub offers a modern AI vocab layer on top of dual-sub viewing.
