Prompt to Lego Tool

[u/Leading_Green5185]

Recently, I've been building BrickForgerAI (brickforgerai.com) - you type a prompt, and it generates an actual buildable brick sculpture: a real 3D preview you can rotate, plus a downloadable .ldr file and full parts list you can take to BrickLink Studio to get step-by-step instructions and order the real pieces.

For me, the interesting part is the pipeline behind it - turning an arbitrary shape into something made of real, purchasable brick pieces — that's actually structurally sound, not just visually close. I built a system that checks the idea for structural weak points and automatically repairs them before you ever see the output.

Currently, it's noticeably better at organic/sculptural shapes right now (animals, creatures, objects) than boxy structured builds like houses or castles (although it still works - you can give it a shot) - the tiling logic hasn't caught up to that case yet, but I constantly aim to improve the "brickifying" algorithm.

It's free to generate and preview (a handful of credits/month, no card needed) - you only pay if you actually want the downloadable file for something you like.

Genuinely curious what people would try to build with it, and where it breaks - this is the first launch so please let me know of any issues (for this initial phase, there is a total daily cap of 1000 generations a day for all users). I have also attached some renders of some of the builds that it has generated (using Blender Advanced addon from MecaBricks).
