We build software and hardware that run on your own device.

An independent technology company in the UK. Two Windows apps on the Microsoft Store, an AI assistant that runs on the user's own PC, and hardware in the lab.

The company

Kirby Systems is an independent technology company in the UK, founded and run by Will Kirby. It ships software today and is developing hardware.

Small language models now run well on ordinary laptops. That makes it possible to build assistants and tools that handle a person's files and questions without sending them anywhere. Kirby Systems is built on the bet that this will matter more as AI moves into everyday software, and every product starts from it.

The lab

Hardware and research that hasn't shipped. Some of it will become products and some won't, so each project shows where it stands.

Working prototype

DIY VR headset

A VR headset built on the open-source Relativty framework. Head tracking and the display work end to end in SteamVR. The shell, designed in Fusion, is being reprinted.
