How does Brickium know which bricks I own?
Three ways: photograph a handful of bricks, type the set number of a set you own, or add a part number. From a photo, Brickium currently recognises about thirty of the most common parts; anything in its catalogue can be added by set or part number. The inventory is yours, kept with your account, and parts used in a model are marked as in use.
Photo
Spread a handful of bricks on a plain surface and take a photo. The photo passes through Brickium’s server to Google’s Gemini API, which recognises the parts; Brickium does not store the photo. Before your first photo the app tells you who receives what and asks for your consent.
Recognition covers about thirty common part types. Unusual or specialised parts are better added by number.
Set number
Type the number printed on a set’s box or instructions and the whole parts list is added at once. The catalogue data comes from Rebrickable.
Part number
For loose parts you can name, add the part number and colour directly. This is the most precise way and works for anything in the catalogue.
What the inventory is used for
Every design is checked against it: a model may only use parts you have, in colours you have. When a model is built, its parts are marked as in use so the next design does not plan with bricks that are already in something.
Questions people ask
Are my photos kept?
No. A photo passes through the server to the recognition service and is not stored by Brickium.
Can I correct a wrong recognition?
Yes. Edit the inventory by hand: change counts, colours or remove a part.
Does scanning cost anything?
No. Adding bricks, scanning, the example and failed design attempts are all free. Only a delivered model uses a creation.
