What is Chamfer

Chamfer is an AI CAD designer that runs entirely in your browser. Describe the part you want in plain words, or show it a photo, and it builds a real 3D model while you watch, checking its own work from every angle and fixing its mistakes until the part matches what you asked for. Fine-tune dimensions with live sliders, then export STEP, STL, or 3MF for 3D printing and manufacturing. Everything stays on your computer.
