Whisker

Whisker is an AI-driven parametric CAD tool that generates production-ready 3D models from natural-language prompts (or reference photos), with the goal of cutting hours of manual feature construction down to roughly thirty seconds per part.

Under the hood it runs a multi-agent pipeline: a generator writes parametric code, an executor builds geometry in a sandbox, and a vision verifier checks the rendered views, with a fixer agent iterating when something is off. Outputs are real B-Rep solids (not mesh approximations) and support extrude, revolve, loft, fillet, chamfer, shell, and boolean operations. Models export as STEP for CAD exchange, STL for 3D printing, or a parametric IR format with a full feature tree for Fusion 360.

After generation you can edit in natural language ("make the walls thinner"), tweak parameters directly, or modify the underlying code. Whisker also handles photo-to-CAD and STL-to-parametric conversions. Typical users span mechanical engineering, AEC, robotics, and hobbyist makers, with example parts including motor mounts, heat sinks, pillow block bearings, electronics enclosures, and pipe fittings.
