What SubX Player is
SubX Player is an Android and iOS media player that adds subtitle translation and language-learning tools. It plays local MKV, MP4, AVI, MOV, MP3, and FLAC files, and streams through M3U or M3U8. Users can display dual subtitles, customize captions, burn captions into video, and export subtitles in other formats. The free plan includes offline translation into 60+ languages and standard on-device subtitle generation. On-device Whisper and Moonshine models generate subtitles for supported audio without uploading that media workflow. SubX+ expands translation to 130+ languages and adds high-accuracy models for English, Korean, Japanese, Spanish, French, German, and Arabic. Its study tools include subtitle seeking, shadowing pauses, auto-repeat, and sentence mining. Sentences can be exported to Anki with optional audio on Android; iOS shares subtitle text and audio. Folders, playlists, background audio, picture-in-picture, casting, and optional Practice Mode round out playback.
