A folder and an installer
An evaluation copy is the application, a shortcut installer, and a page of instructions. It needs Docker Desktop and nothing else, including no internet connection once it has reached you.
It also works before you give it an AI key: the questions it suggests have verified answers stored with them, so a first session works end to end out of the box. Ask outside that set and it says plainly that this needs a model, and where to add a key.
The machine you run it on is a cost you already understand: rent one in the cloud, or buy one. Neither charges per person. What hosting actually costs.
