BrickForgerAI
BrickForgerAI is a web-based service that converts natural-language prompts into custom brick-built models. Users type what they want to make—such as a spaceship, house, or dragon—and the service generates a three-dimensional preview, downloadable LDraw (.ldr) model, a list of required parts, and step-by-step PDF building instructions. The platform is positioned as a way to go from imagination to a physical kit in minutes rather than spending hours manually designing brick layouts. The generation system uses a real, purchasable library of 55 brick parts, including slope angles and curves, and the team is adding more parts and building techniques such as sideways building (SNOT). Models are designed with automatic left/right matching for vehicles, buildings, and other symmetric subjects, while organic subjects retain their natural shape. The service claims most generated models achieve 100% connectivity and display few stability warnings when checked in BrickLink Studio. BrickForgerAI offers a free plan with five credits per month, allowing users to preview basic model information; downloading the actual model and instructions requires payment. Small, medium, and large build options are available, and the generated kits are intended to be ordered as bricks and physically assembled by the user. The service is not affiliated with, endorsed by, or sponsored by the LEGO Group, BrickLink, or Studio.
