Murmur - On-device AI music generation. No cloud, no subscription.

by•
I built Murmur because I was sick of music subscription fees and copyright strikes. It's a 100% offline AI music studio for iPhone. Type any vibe to get royalty-free WAV loops for your videos and games, or go Live to tweak the music in real time.

Hey PH 👋 I built Murmur because I wanted AI music that works offline and without subscriptions. It runs Google's Magenta RT model on Apple Neural Engine directly on your iPhone. Studio mode generates full tracks from a style prompt. Live mode streams continuous music in real time. Would love your feedback. Happy to answer any questions about how the on-device inference works!

The offline angle is genuinely useful for traveling and avoiding sketchy hotel wifi. One thing that would seal the deal for me is a simple export to Ableton or GarageBand project files, so I can take a loop I generated on my phone and actually arrange it into a full track without recreating everything from scratch. Right now it sounds like a great sketchpad but the handoff to a real DAW feels like a missing step.

Love the offline-first approach, downloading it tonight. One thing that would make it a daily driver for me: let me export longer stem tracks beyond short loops, even if I have to render in chunks. Most of my projects need full minute-plus background beds, and stitching four-bar loops gets old fast.
