Why Hew

Built for the way you think

Traditional CAD is powerful but slow. Hew gives you the same precision at the speed of conversation.

Just describe it

No menus. No tutorials. Just type what you want in plain English. "Create a 50mm cube with 3mm rounded edges" — that's it.

> Create a gear with 24 teeth

Real-time preview

See your design materialize instantly in a WebGPU-accelerated 3D viewer. No waiting, no refreshing.

Live at 60fps

Export anything

Download STL for 3D printing, STEP for CNC machining, or 3MF for advanced manufacturing.

STL STEP 3MF

Fully parametric

Every model is defined by code. Change a dimension? Just ask. Need 20 variations? No problem.
