Nomad Sculpt was built for touch. Its interface, its brush ergonomics and its performance budget all assume a tablet and a stylus, and its developer has kept it there — iPadOS and Android, with a limited WebAssembly demo you can open in a browser to try the engine. There is no full Windows or macOS application to buy, so the question "how do I get Nomad on PC" has no direct answer.
The usual desktop suggestions each cost you something. ZBrush is the professional standard and is priced like it. Blender sculpts genuinely well and is free, but it is an enormous program to learn if sculpting is the only thing you came for. 3D-Coat is strong on voxel work and is another paid install. All three are downloads that have to match your machine.
Mold takes the part of Nomad that made it popular — start sculpting immediately, on the hardware you own — and puts it on the desktop through the browser. It renders on WebGPU, so brush strokes are computed on your actual GPU rather than simulated, which is what keeps a multi-million-triangle mesh responsive in a tab. Because it is a URL rather than a build, the same tool covers your PC, your Mac and your iPad, and the sculpt follows your account between them.
What you give up against a native tablet app is the touch-native polish Nomad is genuinely good at. What you gain is a desktop workflow with a texturing pipeline attached: unwrap, paint PBR layers, bake mesh maps and export. Sculpting is free with no time limit and no watermark; exporting the mesh is what a paid plan covers, so you can take something from blockout to textured before deciding whether to pay.
