Quarn is an AI product-engineering service for physical products: describe the thing you want to build, steer the live 3D model in the browser, and leave with a factory-ready package — an open STEP model, dimensioned manufacturing drawings, a structural check (EN 1993 on frames that need one), real-listing sourcing, and a cost estimate.
It is a product engineering tool, not a CAD tool: there is no drawing surface to learn and no seat to buy. You steer; AI agents do the modeling, drafting, material research, and costing. What you leave with is yours — open formats you can take to any shop, with no file conversion.
Quarn accelerates junior mechanical engineers on routine parts, senior engineers on the brackets and fixtures they'd rather not hand-model, and product owners with a clear idea and no drafter to hire. Outputs are preliminary and AI-generated: a qualified professional reviews every package before manufacture, and the engineer owns the build decision.
