Prologue: Audiobook Player for Plex
Prologue is an iOS audiobook player that connects to a Plex server, filling a gap Plex’s own clients have never handled well.
The problem with audiobooks in Plex
Plex can store audiobooks, but its music clients treat them as albums of songs. That means no reliable resume across devices, no chapter list, no sleep timer, and no playback speed control, all of which are basic expectations for audiobook listening. Prologue adds exactly those.
What you get
Chapter navigation, variable speed with pitch correction, a sleep timer, precise resume that survives switching devices, and CarPlay support for listening while driving.
When to use something else
If your library is audiobooks first and Plex is incidental, Audiobookshelf is purpose-built for this and has its own strong client ecosystem. Prologue is the right answer specifically when your audiobooks already live in Plex and you would rather not run a second server.
