Works wherever you watch

Streaming, music, online courses, and learning platforms — plus 1,000+ sites with VTT/SRT subtitles.

Chrome extension

All the platforms above work right in your desktop browser. Plus any site with VTT/SRT subtitles: if a video has subtitles, LinguaCap makes them interactive.

Mobile app

Supports the same sites. Note: Netflix, HBO Max, Crunchyroll, and Prime Video don't allow video playback on their mobile websites — on a phone they only work in their own apps, so use the Chrome extension on a computer for those services.
