What is Mister Blocks?
Take a picture of your LEGO and AI will make a build
Mister Blocks is a LEGO AI that turns your pile of bricks into builds that actually click. Snap your loose bricks — or a model you already built — and it finds every piece, even the hidden ones, then designs four new models made only from what you have.
- Photo in, builds out: designs four new models from your actual pieces
- Every model is checked brick by brick, so pieces sit on studs and nothing floats
- 3D step-by-step instructions and a parts list for every build
- Ask for any build: a car, a robot, a character, a building — the AI researches it and designs it in real pieces
- A gallery of free MOCs with free instructions, from Pokémon to movie scenes
Free to use on the web.
