Plain English to CAD models
kernelCAD turns natural-language descriptions into real, parametric CAD models. Ask for a part, bracket, enclosure, or mechanism and kernelCAD writes editable .kcad.ts source backed by a true BREP kernel (OpenCascade), then lets you inspect topology, run design checks (interference, manufacturability, reachability, load), and export to STEP/STL. Every model opens in an interactive 3D viewer right inside the conversation, so you can rotate, zoom, and review the part without leaving ChatGPT. Unlike a text-to-image tool, kernelCAD produces engineering-grade geometry with named faces and edges, parametric features, assemblies with mates and joints, and validation gates that catch broken or non-manufacturable models before you build.
