Google Flow Music (formerly Riffusion)
changed name and owner twice in a year, and its own terms page returns 403.
google's infrastructure and synthid watermarking behind a product that has been rebranded twice and whose rights documentation we could not open.
the lineage matters because every guide you'll find is about a product that no longer exists under that name. riffusion became producer.ai in july 2025, google acquired it in february 2026, and it relaunched as google flow music in april 2026, rebuilt on gemini and deepmind's lyria 3, requiring an age-verified google account in supported regions.
what google brings is provenance: output is watermarked with synthid, which nothing else in this ranking does, and google's general generative-ai terms state that as between you and google, you retain ownership of outputs, while reserving the right to generate similar content for others.
the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
