Scaling AI literacy and technology education in primary and secondary schools requires enabling every teacher to guide students from an idea to a physical result. This workshop introduces Zhangwen, a multi-agent creation assistant built around the idea that conversation is creation. Three AI roles—a question guide, intelligent engineer, and structural engineer—replace traditional coding and 3D modeling with natural-language dialogue, allowing teachers without technical backgrounds to turn a one-sentence idea into a working object and reduce a typical two-week creation process to about 20 minutes.
