Disclosure: Cart Helper uses affiliate links when you open an item or start cart assistance. Brick Budget may earn a commission at no extra cost to you. The cart assistance saves you repeated searches and quantity entry; checkout remains on LEGO.com. Build your parts list on BrickBudget, then choose Send to Cart Helper from the Budget Summary. Cart Helper opens a checklist beside LEGO.com Pick a Brick and helps you add the matching parts and quantities. It checks the element ID on the page before adding an item, keeps progress visible, and leaves checkout in your hands. Cart Helper also supports LEGO set product pages. It checks the set number before filling the requested quantity. Open one item at a time, or use Auto add all; checkout remains yours. Use the language selector to keep the panel in a supported language. Your budget stays in browser storage. The extension does not include an AI assistant. BrickBudget has separate AI exploration tools on its website; visit brickbudget.com to see what is currently available. Optional measurement, when you choose it, sends usage events and a pseudonymous random installation ID to Google Analytics; budget contents are excluded. BrickBudget is an independent tool.
