Mediux

Play your own audio & video — on-device AI captions, visualizer, AirPlay, PiP, and playlists. Private by design: your files never leave your device.

Mediux is a privacy-first media player for your own audio and video. Everything happens on your device — your files and transcriptions are never uploaded, tracked, or shared.

Play what you already own: media in your folders, music on your device, and videos in your Photos library — all in one clean, fast player.

KEY FEATURES

AI Transcription Turn speech into perfectly time-synced captions — SRT for video, LRC for audio. Powered by OpenAI Whisper running entirely on-device, so no audio ever leaves your phone.

Subtitles & Lyrics Three ways to add captions: a sidecar .srt/.lrc file, an on-device Whisper transcript, or an embedded track inside the file.

Audio Visualizer Watch your music come alive with real-time bar, waveform, and circular visualizers — with customizable colors and particles.

AirPlay & External Display Send video to an Apple TV via AirPlay, or connect a wired HDMI/USB-C display for the full experience — video with subtitles, plus a live audio visualizer with synced lyrics on the big screen. Either way, your phone becomes the remote.

Picture in Picture Keep video playing while you use other apps.

Playback Speed Play from 0.5× to 2× without changing pitch.

Media Library Link MP3, MP4, M4V, MOV, M4A, and AAC files from your own folders, including network drives.

Music Library Play music already on your device — ripped CDs, tracks synced from your Mac, and iTunes Match — browsable by song, album, artist, and playlist.

Photos Library Play the videos in your Photos library — recordings, screen captures, and saved clips. Browse by album, add to playlists, and transcribe captions.

Playlists Build your own playlists from any source, in any order — and transcribe lyrics to watch them in the visualizer as the track plays.

PRIVATE BY DESIGN No accounts. No cloud. No tracking. Your media stays yours.
