Own your music. Shape your library. Play it across your devices.
Icoustic is a personal music system for building, managing, and enjoying a collection that truly belongs to you.
Own your collection
Build a lasting library of MP3, FLAC, and M4A files with serious browsing, playlists, ratings, artwork, queues, and metadata editing. Your edits remain with the music, while open import and export formats keep your library portable.
Connect your devices
Use your Mac, iPad, and iPhone as a flexible ecosystem of libraries, players, and remotes. Choose where the files live, where the sound comes from, and which device controls it.
Manage it without limits
Connect your preferred AI through MCP to audit metadata, identify duplicates, organize artwork, and create playlists—with changes reviewed before they are applied.
