ArgilCAD turns plain-language prompts into parametric solids by generating build123d code, which you can refine by chat or edit directly in its code editor. It has a live 3D viewer, makes dimensioned 2D drawings and exports STEP, STL and GLB. It supports several AI providers. The free plan includes the modelling tools with your own AI, unlimited code editing, exports and drawings; Starter is $5 and Pro $20 a month.

The free plan means bringing your own AI. The macOS app is Apple Silicon only.
