HayaiLearn
Japanese video immersion
Free · In‑App Purchases
Learn Japanese active and passively with AI Roleplay and watching Japanese Youtube videos. We use AI to help you understand Japanese subtitles easily!
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.
