How accurate is the brick'em scanner?

brick'em is trained on 18,600+ minifigures using BrickLink's complete catalog. You get the exact BrickLink ID, name, and market price for every figure scanned.

Do I need a credit card to start?

No. Start your 14-day free trial with no payment due today. Cancel anytime during the trial and you won't be charged.

What platforms can I export to?

Whatnot, eBay, BrickLink, Shopify, BrickStore, and generic CSV. Each export is formatted specifically for that platform so you can bulk upload immediately.

Is brick'em just for minifigures?

No. brick'em identifies both minifigures and individual parts. The parts scanner identifies pieces by color and looks up prices per variant.

Can I cancel anytime?

Yes. Cancel or downgrade from your settings page. No contracts, no cancellation fees, no questions asked.

I already have a system that works. Why switch?

If your current process handles 200+ figures a week without eating your weekends, keep it. But if you're spending hours on manual lookups, brick'em does the same work in minutes. Most sellers try the 14-day free trial and never go back.
