HayaiLearn

HayaiLearn turns your favorite YouTube videos into immersive Japanese learning materials, so you can study the language through content you actually enjoy instead of dry textbooks.

Find any Japanese video on YouTube, then import it into HayaiLearn to watch with dual subtitles, AI-powered explanations, and a pop-up dictionary that helps you understand every line with ease.

Once a video is imported, you can watch it from any device—mobile, tablet, or desktop—so your learning fits naturally into your day, wherever you are.

Sentence mining becomes effortless: save subtitles, take notes, and review them together with the videos using built-in SRS spaced repetition, so what you learn actually sticks.

Organize your favorite videos into albums, and easily search video-playable example sentences for any word, all pulled from the videos saved in your albums.
