Every diagram your engineering docs need — as hand-drawn Excalidraw, generated by your AI. Twenty-five diagram types. Architecture and flowcharts, but also sequence diagrams, state machines, ER models, swimlanes, timelines, Gantt charts, quadrants, funnels, and hand-sketched bar/line/scatter charts. No coordinates to hallucinate, no Figma, no stale PNGs.
