Mediux

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. Multi-task Let another app's sound keep playing alongside Mediux — Mix keeps both at full volume, or Duck lowers the other app instead. Perfect for watching in Picture in Picture while you play a game. Designed for multitasking with the screen on. Sleep Timer Drift off to your media. Stop playback after a set time, at a chosen hour, or at the end of the current track — with a gentle fade and a countdown on the Lock screen 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. iPhone Duo Support The library and player sit either side of the fold — and when you stand it up, the player moves to the upright half. Download Keep files from a network or USB drive on your iPhone, so they play even when the drive isn't connected — still in their folders and playlists. PRIVATE BY DESIGN No accounts. No cloud. No tracking. Your media stays yours.
