What is BrickForgerAI?
BrickForgerAI is a web application that generates custom brick model designs from text descriptions. Users type a prompt describing what they want to build, such as a spaceship, house, or dragon, and the AI produces a 3D model using a library of 55 real, purchasable brick parts. The library includes a variety of slope angles and curves for smoother surfaces and is continuously expanded with new building techniques, including sideways building (SNOT). Generated models can be previewed in 3D with part count and dominant colors. For a fee, users can download the model as an .ldr file, a full parts list, and a step-by-step PDF build guide, enabling them to order the physical bricks and build the model. The free tier provides 3 credits per month for previewing and limited use. The tool is designed for hobbyists, LEGO enthusiasts, and anyone who wants to quickly turn ideas into physical brick kits. It is not affiliated with the LEGO Group, BrickLink, or Studio.
