BrickCatalog knows ALL Lego sets. Ok, almost all of them. A lot of them, about 13000 sets and 4000 different bricks. The app will suggest what you can assemble with the bricks you have.

First you will need to index all you have. This is how it works: you spread out a couple of dozens bricks on the table, photograph them, Neuronet identifies them and then does the calculations and indexing adding them to your personal Catalog. Then you repeat the same with other bricks. If you have many Legos it will take you a while to create your Catalog but its definitely worth the hassle.

Life with the BrickCatalog is a brand new life. You will see all the models you can put together. All Lego series are in: a couple of trains can make up for an ancient castle, and a spaceship can turn into a Magic Cave. If a particular model is not assembled that easily BrickCatalog will get you an instructions manual. After you have put a model together you can mark it off in your Catalog so that the bricks you have used become temporarily unavailable.

There is also no need to photograph and scan the bricks of every new Lego set you buy - you can simply find it in the BrickCatalog database. The app will automatically add up all the new details.

BrickCatalog doesn't distinguish the colors yet. But it's on our to do list.

We have created and launched it just very recently. We want to be friends and communicate with everyone. Please write to us -!
