Create and edit CAD models into production-ready prototypes
Whisker turns plain-English descriptions into production-ready parametric CAD models. A multi-agent AI pipeline generates real B-Rep geometry, verifies it using a proprietery algorithm, and iteratively fixes issues - all in under 1 minute. Every dimension is a tunable parameter. Export one-click to STEP, STL, or natively into Fusion 360 with full feature trees and linked user parameters. Real parametric CAD. Free to start.
Hey Product Hunt! I'm Danila, founder of Spatial Kittens and maker of Whisker.
The problem: Translating a design idea into a parametric CAD model takes hours of manual feature construction - even for experienced engineers. Sketching a flange or turbocharger housing means dozens of constrained sketches, extrusions, and fillets before you can even evaluate the concept.
Why existing tools don't solve this: Other AI CAD tools produce mesh approximations or static geometry. You get a shape, but no parametric control, no feature tree, and no way to tweak dimensions without starting over.
Whisker is different:
- Real parametric output — every dimension is an editable parameter with min/max constraints, not a frozen mesh
- Custom geometry verification — a geometry agent analyzes 6-view renders and iteratively fixes issues before marking a model complete
- Native Fusion 360 import (beta) — our add-in creates real features (extrusions, fillets, chamfers) with linked User Parameters, not a STEP dump
Free tier: 10 generations/month, full parametric output, STEP & STL export. No credit card required, free forever.
We're live at https://whisker.spatialkittens.com and onboarding enterprise users from the waitlist (30+ companies already queued).
I'd love your feedback on two things:
1. What types of parts would you try generating first?
2. Besides Fusion 360, which CAD platform integration matters most to you?
We'll be here all day answering questions!
