Music for ads, games and creators with a paper trail. A prompt guard refuses or strips named artists, songs, labels and voice imitation (code rules, then one receipted typed judgment), the track renders on MiniMax-Music3 or ACE-Step, and a CPU check scores it against a catalogue of openly licensed recordings. Each track ships with a C2PA credential and a signed certificate that states the model, seed, checks, similarity score and the exact licence.

You give it
A music brief (genre, mood, instruments), optional lyrics, or an audio file to check

Brief

When the prompt names someone

A guard and a triage check, not a rights clearance. MiniMax-Music3 output must be credited "Powered by MiniMax-Music3". No copyright in the output is claimed: the US Copyright Office holds that prompts alone do not make a work protectable. Each demo session renders 3 tracks.

Write a brief and generate. The prompt check runs first; a refused prompt never reaches the GPU.

Check any track

Score a file from anywhere against the reference catalogue: 240 openly licensed recordings from the Free Music Archive. Try a pitch-shifted copy of one of them to see it flag. The file is checked in memory and not kept (20 MB at most).
