Music made together, by anyone.
AlterJam turns making music into something social and simple. A jam is a shared song — you add your part, others add theirs, and together you build something none of you could alone.
How it works
Four steps from an empty track to a finished jam.
Start or join a jam
Open a jam someone started, or create your own from scratch. Every jam is a shared song waiting for more parts.
Record your take
Add vocals, guitar, drums — whatever you play. Record in simple mode for a quick take, or advanced mode for more control.
Let AI polish it
AI cleanup removes bleed and noise, and auto-mix balances the volume of every track so the jam sounds right.
Share & discover
Publish your jam to the feed, get reactions from the community, and swipe through fresh jams from around the world.
No studio required
Everything happens on your phone. Whether you’re a seasoned musician or just humming an idea, AlterJam makes it easy to get your sound into the mix.
