SubX turns any movie, show, podcast, lecture, or video file into a powerful language-learning experience. Learn naturally by watching, repeating, translating, and saving phrases directly from meaningful content.

⚠️ Important Note

SubX works with videos and audio that include subtitles, or with subtitle files you add separately.
It does not automatically generate subtitles from videos at this time.
This design ensures accuracy, full control, and a better learning experience for serious language learners.


🎯 Who SubX Is For

SubX is designed for language learners who study through subtitles, shadowing, and repetition.
