Turns YouTube videos into an interactive language learning lab with clickable subtitles, context-aware AI explanations, and a spaced repetition review system.
LinguaMaster is a desktop application that transforms YouTube videos into an interactive language learning environment, solving the problem of passive watching by enabling active engagement with subtitles and contextual explanations.
