Icoustic

All your music. All your devices.

Icoustic makes the music you own — on your Mac, iPad and iPhone — one library you can play to any device, take with you, and keep tidy with your own AI. No account, no cloud: open it on two devices on the same Wi‑Fi and they find each other. Approve once on each device, or turn on Auto-join.

Preview on this iPhoneNight Bus is playing on this iPhone’s headphones. Listen here first, then send the playing track to the iPad when you want it on the speakers.

Save to device

Take it with you

Pin a playlist with the heart and those tracks are on this device — not a link to them. A pin freezes membership at pin time, so it plays with every other device off.

MCP

Connect your AI

Icoustic isn’t an AI product. On Mac, connect Claude, Cursor, or ChatGPT Desktop to your library over MCP. It proposes; you review every field in MCP Actions; nothing is written until you approve. Every edit can be rolled back.
