Harmonai

Harmonai is a web-based Stability AI Lab and community project for musicians, producers, DJs, and sound designers who want open-source tools for generative audio and sound creation.

Key capabilities include:

• Open-source generative audio tools for creating unique sounds and compositions, suitable for experimentation and production workflows
• Custom, infinite sound libraries, generated with AI and tailored to specific creative needs
• Dance Diffusion, a model for generating production-ready audio waveforms across the full auditory range
• Community collaboration via shared creations and development, with an open invite to participate

Pricing: Free (open-source tools).

What makes it notable: It operates as a Stability AI Lab with an explicit focus on artists building AI for artists, and it centers generative audio models like Dance Diffusion to expand sound design and genre exploration beyond traditional sample-pack limits.
