What it does: You watch short clips from real movies and TV shows, then get quizzed on the vocabulary you just heard. The app tracks every word automatically and adapts to your level. 20+ languages.
How it evolved: Started as an iOS app for interactive streaming subtitles. Then I added curated video clips with quizzes. Then vocabulary tracking, spaced repetition, and personalized learning paths. Now it's iOS + Android + a Chrome extension (dual subtitles for Netflix and YouTube).
The whole thing is a solo project. Along the way it won a $30K prize at Hungary's biggest startup competition, which gave me the push to go full-time on it.
Stack: Swift (iOS), Kotlin (Android), Chrome extension.
Would love to hear what you think, especially from anyone who's tried learning a language from media before. What worked? What didn't?
