zCAD AI

What makes it different

zCAD AI generates parametric 3D models from plain language, built for designers, makers, and engineers. Describe a part or a whole assembly and it returns an editable, dimension-driven model built on real CAD geometry — not a static mesh. Complete assemblies come out of a single prompt, with mates between parts, and you can refine in plain language or edit dimensions directly in a browser-based CAD editor.

The distinction matters for anyone who actually manufactures things: a mesh looks right but cannot be edited, toleranced, or machined. zCAD AI models export to STEP for use in any CAD tool, so the AI output slots into a real engineering workflow instead of ending as a render. A free plan covers 200 credits a month, with Plus at $49.99 a month and Pro at $89.99 a month for private models and larger credit pools.
