About HayaiLearn
Learn Japanese the way you'll actually stick with - by watching the YouTube content you already love. HayaiLearn ("hayai" means fast) turns any Japanese video into an interactive lesson with AI-powered subtitles, instant contextual translations, and real speaking practice. Immersion in easy mode. Most learners quit because they feel overwhelmed, short on time, or have nowhere to practice. HayaiLearn fixes all three: enjoyable content keeps you motivated, bite-sized study fits any schedule, and an AI conversation partner gives you unlimited practice. Learn from videos you enjoy 20,000+ Japanese videos, plus study any YouTube video yourself Every video graded 1-10 by difficulty, so you always find content at your level A personalized feed that surfaces what's most comprehensible to you right now AI that makes hard content easy Fully AI-parsed subtitles - far more accurate for slang and casual speech Tap any word for the meaning that fits this sentence, not a wall of definitions One-tap AI explanations break down grammar and sentence patterns on demand Actually speak the language Roleplay conversations built around the exact words and grammar you're learning The AI voices the scene, listens to your reply, and gives instant, explainable feedback Shadowing and pronunciation grading to sharpen your accent Remember what you learn Smart spaced-repetition Review for reading and listening, grounded in real clips Flashcard or multiple-choice, drilled in the context you first saw the word Frequency-based vocabulary lists with JLPT N5-N1 filters Track real progress XP across all four skills - Reading, Listening, Writing, Speaking Level up, build daily streaks, and watch words go from "just started" to "mastered" Mine and save sentences, organize videos into albums, and study your way Built for the full journey Input builds comprehension. Output builds fluency. HayaiLearn is the only tool that covers both - turning the shows you love into the fastest path to speaking Japanese.
