Murmur: On-Device AI Music

Every track is one-of-a-kind, made just for you — on your device, in moments. No cloud. No repeats. Just music that fits right now.

Murmur is an offline AI music generator for the people who actually need the music — video creators, vloggers, podcasters, and game developers. Turn text prompts into 100% royalty-free instrumental loops and soundtracks — generated entirely on your device, with no internet required.

Describe a scene, a vibe, or a setting — "upbeat acoustic for a vlog intro," "warm lo-fi for a podcast transition," or "dark synthwave for a game menu" — and Murmur composes original audio just for you. Nothing is streamed from a server. The AI runs privately on your iPhone's Neural Engine, so your tracks belong entirely to you. Murmur automatically adapts to your device — newer iPhones unlock the richest sound quality instantly, while older models use a lighter engine tuned to still sound great, with nothing to configure.
