Splitting a drum kit into stems, metering a master, opening a native DWG, slicing a part for the printer — the software that does this is either a native install, a cloud queue or a licence. Here it runs in the browser tab on your own machine. Nothing is installed, nothing leaves your computer, nobody signs in.

The way in is the same for a hand and for an AI agent. Every tool declares what it can do once, and that one registry drives the buttons, the command line and the agent's tool list alike — 78 commands across the three tools, each with a schema. It feeds the accessibility tree too, so the sentence a screen reader hears from the drawing is the sentence an agent gets back.

The audio suite

seance sample workbench /tools/seance everything you do to a sample before you use it — see it as a spectrogram, loop it to its beat grid, screw the pitch, pull the drums apart into kick, snare and cymbals, cut it at the hits and check how loud it really is

The workbenches
