# HIIE

> HIIE is an AI workflow operating system that turns a hardware idea into a real product, the product into a workflow, and the workflow into a running business — design, CAD, sourcing, automations, and payments in one workspace.

HIIE is built by Arthur Labs, Inc. (Wyoming C-Corp, Omaha, Nebraska). The full engine is free with your own API keys; paid credit plans add managed inference. Markdown mirrors of the key pages are linked below.
