About ZeroPop
Built by collectors.
Trusted by graders.
ZeroPop is an AI card grading scanner for iOS. We built it because every other grading tool we tried either gave us a vague single grade with no breakdown, or stopped at the prediction without telling us whether the card was actually worth submitting.
What we do
Every card you scan gets four sub-grades on a 1 to 10 scale (corners, edges, surface, and centering) using AI vision models calibrated against thousands of real PSA submissions. On top of those sub-grades we estimate PSA, BGS, and CGC grades with confidence scores, map every defect to the card zone where it lives, detect 20+ variants (1st Edition, Alt Art, Prizm, etc.), and track your collection value over time against live eBay market data.
How we stay accurate
Our grading predictions are calibrated against thousands of real PSA, BGS, and CGC submissions we've personally sent in. We publish our methodology, disclose confidence intervals, and ship updates when population reports shift the math. When we're unsure about a prediction, we say so.
Every article on our blog is written by someone who actively collects and grades cards, not a freelance SEO writer with no stake in the outcome. We show our work, include specific card numbers and real sale comps, and update posts when the market moves.
