OpenMusic.ai is a cloud-based AI music generation platform launched in November 2025.

OpenMusic offers a wide range of genres: Hip Hop, Jazz, Reggae, Pop, R&B, EDM, Country, Folk, Rock, Blues, Classical, Disco, and Funk. The platform supports 9 languages including French. Beyond generation, OpenMusic integrates a complete production tool suite: vocal removal, stem separation, AI mastering, MIDI editing, audio-to-MIDI conversion, cover creation, and automatic music analysis (BPM, key). All generated music is 100% royalty-free with commercial license included from the Starter plan, allowing use on YouTube, Spotify, TikTok, and for monetization without legal risk.
