Producer.ai — the app that started as Riffusion — was bought by Google and renamed Google Flow Music. If you're looking for somewhere else to make songs, Kenerate's Music Studio puts four engines in one place.
Quick answer
Updated
Producer.ai no longer exists under that name. It began as the open-source Riffusion project in 2022, rebranded as Producer.ai in 2025, was acquired by Google in February 2026 and was renamed Google Flow Music in April 2026 — producer.ai and riffusion.com now redirect there. Kenerate's Music Studio is an alternative that runs four engine families in one place — Ken Music, ElevenLabs Music, Mureka and MiniMax Music — for songs, your own lyrics and instrumentals, with 25 free credits and one-time credit packs that never expire.
