YouTube is already the largest living textbook on earth. ShadowFlow gently layers your native language, your target language, and a word-level dictionary over the videos you already watch. Tap a word to see its meaning, hold to save it for review. Shadowing, read-aloud, and repeat practice all run on your normal video — no separate curriculum, no streak pressure.

What it does
  • Real-time dual captions (native + target language)
  • Tap any word for dictionary & vocabulary list
  • Shadowing, read-aloud, and loop practice
  • Private progress log and gentle review reminders
