Your tools, one click away.
A free, open-source sidebar for Windows. It docks to any edge of your screen, keeps your notes and carries only the plugins you choose.
Play music out of thin air.
A theremin simulator for Meta Quest. Play with your bare hands: one hand sets the pitch, the other the volume, and you never touch a thing.



Swipe your sentence, say it out loud.
An open-source communication app for people who can't speak or find speaking hard. Build sentences by swiping through your own words, then have them read aloud.
Start a VR game by ticking boxes.
An open-source starting point for VR games on Godot 4.6 and OpenXR. Every common VR mechanic is already wired into one player rig, and each one can be switched on or off from a single config file.
KO48 isn't a company. It's a shared home for independent projects: a Windows sidebar, a VR instrument, a garden on your desktop, a communication app and a starting point for VR games.
New projects are added here as they take shape.
