Prologue is an audiobook player that connects to a user’s Plex or Audiobookshelf library. It brings books from those servers into one listening interface, with browsing by author, collection, or series. Listeners can save titles for later, download supported books for offline playback, bookmark passages, add notes, and review listening history and statistics.
Playback tools include speed controls, sleep timers, per-book settings, and audio adjustments. The listing also describes transcript-following features for supported audio and languages, plus integration with iPhone, iPad, Apple Watch, CarPlay, Siri, Shortcuts, and widgets. Prologue does not sell books or include its own audiobook catalog; users supply access to their own server or files.
The app is free to download, with additional capabilities behind a one-time Premium unlock. Apple Watch offline listening requires a separate unlock. A compatible server and properly configured library are necessary, and transcription support varies by device and language. We have not tested server setup, file compatibility, or synchronization across devices.
