Pixel City · interface experiments for AI software

Worlds that let you see what your AI is doing.

A complex AI system is hard to follow: many agents, many steps, and no way to tell what's going on. Our bet is world building. Put the system in a place, give its agents names and desks, and people can see what it's doing, understand it, and step in.

Luma World

Your interactive world of AI agents.

A world for development work. Each agent is a character at a desk: you can see what it's working on, it turns to you when it has a question, and it tells you when it's done.

The bet

Why world building.

It's natural

You already know how to walk into a room and see who's busy. A world uses what people know. A dashboard asks them to learn it.

It's already 3D

A world is a place, not a page. So when VR and other new screens become everyday, people can step inside the same world. Today it runs on your computer screen.

The interface is changing too

Programming used to mean writing code. Now a lot of it is writing prompts. We believe the same shift is coming to the layer people see and use, and that it moves towards worlds.

Vision

What we hold to.

A universe of interactive worlds where people learn, work, and create through familiar, personal experiences with AI.

AI you can see

What an agent is doing is on screen while it happens, not buried in a log.

In a way people understand

Characters, places and conversations. Things people already know how to read, so nobody has to learn how the system works first.

With you, not instead of you

You can step in at any point. AI takes the boring parts, so you have more time for the parts you enjoy.
