What is Harmonai?

Harmonai is a lab within Stability AI that builds and publishes generative audio tools as open source. Its stated goal is to make music production easier to get into and more enjoyable.

The project focuses on letting artists create their own sounds, including building custom sound libraries with generative models. Work is shared openly, and the site invites people to join its community and get involved.

It is a good fit for musicians, producers and audio developers who are comfortable with community-driven open-source projects. It is less suited to people looking for a polished, single-click music app with support and plans.
