WattLoop is a screening tool for factory energy. You give it a photo or a description plus an electricity bill. It builds a 3D twin that matches the bill, finds waste, and tests fixes in simulation. A checker rejects impractical fixes, and the agents try again. It then writes a report, and the engineer makes the final call. It saves the engineer time on the first look and does not replace them.
