Brickium: AI Brick Builder

Take or choose a photo of an animal, a vehicle or a building, and Brickium designs a model from your bricks, with 3D steps you can rotate and zoom. Or describe an idea.

Brickium turns the bricks you already own into something new to build.

Add your bricks by set number, part number or photo. Brickium suggests what it sees in a photo; you check the list and quantities before adding anything. Sets you keep built stay in Collection until you take them apart.

SAY WHAT YOU WANT TO BUILD

Describe an idea in your own words or choose an inspiration. When you have available bricks, designs use those parts by default. You can allow common extra parts; if no bricks are available, the design lists the parts you will need.

Before delivery, Brickium checks the design against the chosen parts, geometry, collisions and support. These checks cannot guarantee every physical connection or assembly step. Do not force a piece that does not fit.

OR BUILD FROM A PHOTO

Take or choose a photo of an animal, a vehicle, an object or a building. Brickium designs a model from your bricks that catches its look, and checks every design before showing it. When a design can't be made, it tells you plainly and no creation is used. Photos with people, characters or logos cannot be made.

BUILD AND KEEP YOUR WORK

• Follow illustrated, step-by-step 3D instructions. Rotate and zoom the model as you build. • Review the parts list and see missing pieces before starting. • Return to a build where you left off, or take it apart to free its parts. • Reopen finished creations from Builds and taken-apart creations from History. • Ask for another design from an unstarted one; the original stays saved.

Start from Home or Builds and return to the same working request. Once the server accepts a request, you can leave the screen or switch apps. You can choose to enable a completion notification. Successful designs are saved in Builds.

Try the example on Home without an account.

CREATIONS AND PACKS

A new account receives one creation, and another after its first finished build. A creation credit is used only when a design is delivered; failed attempts do not use a creation credit. Before buying or redeeming a pack, the free trial allows up to three design attempts, and some failed attempts count toward that limit. Adding bricks, scanning and viewing the example do not use creation credits; scan limits may apply.

Four one-time packs add 2, 5, 10 or 20 creations. There is no subscription, and credits do not expire.

PRIVACY AND LANGUAGES

Part-recognition photos, AI cover-background photos and photos you build from are sent to Google's Gemini API and are not stored on Brickium's server. Design requests are sent to OpenAI. The app explains and asks for permission before sharing for each AI feature; you can change your choices in Me. You can delete your account and associated app data in the app.

Brickium is for people aged 18 and over. The interface is available in English, Simplified Chinese, Traditional Chinese, Danish, German, French, Japanese and Spanish.

Part names and colours in the build checklist are currently shown in English.
