Sisyphe · About Index What we do Who runs it Background Elsewhere

A small company with a long run-up

Sisyphe builds AI for art, music and creative tools: agents that perceive a live environment and work inside it, whether that is a DAW, a stage, a gallery or an archive.

01

What Sisyphe does

A model that can see the whole environment and notice what changed is more useful than a chatbot beside it with a list of commands.

Sisyphe is independent of any employer. Client work never touches what the founder does at a day job, and the day job is not for hire here.
