The drawing belongs to you.
I trained for years to put my name on a set of drawings. That signature is a promise that the work is sound and the code is met. I am not going to hand that promise to a tool I cannot inspect.
Every AI I tried wanted my project on its servers. Each one answered code questions with the confidence of a colleague and the accountability of none. For stamped work, that is not a shortcut. It is a risk with a friendly voice.
So I built the opposite. ArchAI runs on the machine in front of me. It answers from the code, and it shows the section every time. When it is not sure, it says so rather than inventing a citation. The project never leaves the studio.
This is for the solo practitioner and the three-person firm. The people who are the architect, the drafter, and the office manager at once. You deserve a sharp tool that respects the line you have drawn around your clients work.
It cites the code. It does not stamp the drawing. You do.
