⬆ Import

Image → 3D

Upload a photo, sketch, logo, AI render or transparent PNG. Paloan removes the background, reads the shape and shading, and builds real castable 3D: relief charms, silhouette pendants, coins, signet faces — or recognises the jewelry type, metal and stone from a product photo.

Drop a product photo / image, paste (Ctrl+V) or browse / camera

✨ No image? Generate a concept (free AI)

Free: uses Puter.js (no key, free sign-in) or your free Pollinations key. The result loads here, ready for Photo → 3D.

✎ Sketch a shape

Pen

Concept → CAD

Describe the piece, or drop AI-generated reference images. The offline parser works instantly; Claude adds full engineering reasoning, reads images and returns buildable parameters.

Mesh → NURBS reconstruction

Load an AI-generated or scanned mesh (STL, OBJ, GLB/GLTF, FBX, PLY). Everything runs locally in your browser; nothing is uploaded.

Rhino & Grasshopper export

One Python file rebuilds this exact design as clean NURBS polysurfaces on a layer tree (Metal / Stones / Cutters), with real boolean stone seats. Works in Rhino 7 & 8 and as a GhPython component (input P = JSON, outputs a breps, b report).
