Riffle

Riffle, built by Riffle, Inc., is a browser-based music creation and collaboration platform where users drag and drop audio, lyrics, sounds, images, embeds, and notes onto an infinite canvas to compose music collaboratively without needing specialized software knowledge. It supports layering and stacking of licensed samples and instruments, real-time collaboration with multiple users editing simultaneously from anywhere, and a Sous Chef AI co-producer that generates suggestions for ideas and production work while users retain full control. Riffle also supports public sharing, letting users publish 'drops' (public tracks) and remix others' work. The platform is completely free, with Riffle committing to transparent pricing should premium features ever be introduced.
