AI has a blind spot:
understanding the person.

Theia is the foundation model for human-state intelligence. Measured in real time from eye movement alone, it knows if:

you’re focused or fatigued
you’re engaged or overwhelmed
you’re resilient or burning out

How it works

Eye movement in. Human-state intelligence out.

A fully automated pipeline and one foundation model turn passive eye movement behavior into real-time capabilities, alerts, reports, and interventions, on any camera-based device. It’s the human context AI has been missing.

Any AI agent can use Theia to trigger alerts, reports, and actions in your app.
Runs at the edge
On ordinary CPUs you already have. No GPU, NPU, or cloud required.
Any camera-based device
Phones, tablets, laptops, webcams, smart glasses, XR headsets, vehicles, aircraft.
Easy to deploy
One SDK across every platform. Integrate in minutes.
Where Theia works

Wherever understanding people matters.

The same model and capabilities across every field and device, with gains you can measure for the person and the organization.

Defense, government & space
Assess pilot, crew, and operator readiness with objective data, from simulators to mission environments.

Theia is a wellness and performance tool. It is not a medical device and is not intended for the diagnosis, treatment, mitigation, or prevention of disease or other medical conditions.

What you do with it

Theia turns its capabilities into action, in plain language.

Describe what outputs you want and Theia Harness delivers them in real time. Create alerts, reports and interventions, and send them to the tools you already use. Manage users, deploy to any device, and govern privacy. No tech team required.
