Why “Video × AI” Keeps You Motivated—and Growing
Swipelingo turns any YouTube video into an AI-curated learning session. It pulls authentic Japanese phrases—around 10-20 words long—and turns them into swipeable flashcards. Zero manual “sentence mining,” yet your listening, speaking, and vocab all climb at once.

Perfect for Learners Who…
Want real conversational Japanese with dual JA/EN subtitles
