BrickForgerAI

BrickForgerAI is a web-based tool that turns text prompts into custom brick models. You type what you want to build — a spaceship, a house, a dragon, anything — and the AI generates a 3D model along with a parts list and step-by-step build instructions. The output comes as a downloadable .ldr file (compatible with BrickLink Studio) and a PDF guide. The free plan gives you 3 credits per month to preview and test, and you pay only when you want to download the full build.

The tool uses a library of 55 real, purchasable bricks, including slope angles and curved pieces for smoother surfaces. BrickForgerAI is constantly improving stability and connectivity, even supporting sideways building (SNOT). Most generated models have 100% connectivity, with few flagged issues in BrickLink Studio’s stability checker. You can choose from three model sizes — small (15 studs), medium (22 studs), and large (30 studs) — and preview the model in 3D before purchasing.

BrickForgerAI is best for hobbyists, builders, and anyone who enjoys creating with physical bricks. Instead of designing from scratch or hunting for existing instructions, you can describe your idea and get a ready-to-build kit in minutes. Teachers, parents, and toy designers can also use it to quickly prototype custom builds. Note that BrickForgerAI is not affiliated with LEGO, BrickLink, or Studio — it’s an independent tool that generates compatible models.
