  SmartLearner — Learn languages while watching Netflix & YouTube.
  
  Turn your favorite shows into language lessons. SmartLearner replaces the default player with a powerful learning interface designed for language learners.
  
  🎬 DUAL SUBTITLES

  Click any word in the subtitles to instantly see its meaning, pronunciation, and usage examples — powered by AI.
  
  🤖 AI-POWERED EXPLANATIONS

  📝 VOCABULARY BUILDER
  Save words you encounter while watching. Track your learning progress with status levels: new, learning, and mastered.
  
  🧠 BUILT-IN QUIZ SYSTEM
  Test yourself on saved words with auto-generated quizzes. Spaced repetition ensures you remember what you learn.

  🔒 PRIVACY FIRST
  All data stays on your device. No accounts required. Bring your own OpenAI API key for AI features.
  
  Perfect for language students, polyglots, expats, and anyone who wants to learn naturally through immersion.

  SmartLearner transforms Netflix and YouTube into your personal language classroom. Instead of passively watching, you actively learn — clicking words, saving vocabulary, and testing yourself with built-in quizzes.
  
  HOW IT WORKS
  
  SmartLearner replaces the default video player with a learning-focused interface. Original and translated subtitles appear together so you can read along in both languages. Click any word to see its meaning instantly. Save it to review later.
  
  FEATURES
  
  Dual Subtitles — Show original and translated subtitles at the same time. Customize font, color, size, opacity, and shadow for each line independently. Choose from built-in presets (Classic, Minimal, Cinema, Neon, Pastel) or create your own.
  
  Click-to-Translate — Tap any word in the subtitles to see its translation, pronunciation, and example usage. No copy-pasting, no switching tabs.
  
  AI Sentence Breakdown — Get grammar explanations, cultural context, and word-by-word analysis for any sentence. Powered by your own OpenAI API key.
  
  Vocabulary Tracker — Every word you save is tracked with status levels: new, learning, and mastered. Build your personal word bank as you watch.
  
  Spaced Repetition Quizzes — Auto-generated quizzes based on your saved words. The system schedules reviews using spaced repetition so you retain what you learn.
  
  AI Coach Panel — A contextual language coach that generates exercises based on what you are currently watching.
  
  Full Customization — Multiple color themes (Gold, Emerald, Purple, Rose, Ocean, and more), light and dark mode, adjustable playback speed, auto-pause after each subtitle, and configurable panel positions.
  
  SUPPORTED LANGUAGES
  
  Works with any subtitle language available on Netflix and YouTube. AI features support 20+ languages including English, Spanish, French, German, Japanese, Korean, Chinese, Arabic, Portuguese, Italian, Turkish, and more.
  
  PRIVACY
  
  All learning data is stored locally on your device. No account required. AI features use your own API key — your data is never stored on our servers.
