Sisyphe · creative AI

AI that acts
in the studio,
on stage,
in the world.

We build AI that works inside the instruments, tools and spaces artists already use: DAWs and plug-ins, collections and archives, installations and stages. Not a chatbot beside them, but agents that see the whole environment, act in it safely, and notice what changed. The first one we shipped, Sideman, gives Claude the whole of Ableton Live.

For music-tech companies, labels and studios, museums and galleries, festivals and artists.

Layer one

Perceive

What the model can see decides what it can do. We build the senses: bridges into an application’s object model, observers that report what a human did by hand, embeddings over a collection, sensors on a stage.

Layer two

Reason

Grammars, skills and evaluation. We teach the model how a domain is shaped so it looks instead of guessing, and we measure coverage against the real system rather than claiming it.

Layer three

Act

Real writes with real undo, sound, light and machines that answer in real time, and a guard before anything destructive. An agent that acts has to be safe to be wrong.

Why Sisyphe

Sisyphus pushed the same rock up the same hill, forever. Creative work has more of that than anyone admits: the fortieth track rename, the stems you export one more time, the catalogue you re-tag by hand, the cue you rebuild because one setting was wrong. It all has to be done, and none of it needs you.

We build the thing that pushes the rock. You keep the part that needs you: the taste, the judgment, the call.
