Give any MCP agent — Claude, ChatGPT, Gemini, Mistral — a photo, a paper pattern or a brief, and it drafts on a mannequin built from your measurements while you watch. Or rework what you have: refit it to another size, split a piece, add a pocket, move a seam — just ask. Seamcult audits the geometry, so the agent works from facts, not guesses. Sketch a fix on the canvas and the agent gets it as an image. Print on A4 at home, export PLT or DXF, or share a read-only link. Free in early access.

Could you build this?
Partial The MCP and UI layer is buildable, but generating accurate sewing patterns that fit real bodies and audit geometry correctly demands deep pattern-drafting and garment-construction expertise.
What it would actually take: Build a 2D CAD kernel for pattern pieces with seam and grainline constraints, a body model fitted from measurements, and an MCP server exposing the operations to LLM agents, plus a 3D preview. The hard parts are drafting algorithms that produce wearable fits, geometric validation of seams and ease, and garment-construction knowledge, which requires pattern-making expertise alongside the software work.
