How accurate is AI card grading compared to PSA?

Our AI grading achieves 95% accuracy within ±1 grade point when compared to PSA final grades. This allows you to pre-screen cards and avoid expensive grading fees on cards unlikely to gem.

How many credits does complete card grading cost?

Complete card grading costs 1 credit per card, which includes the AI grade plus the centering and crop overlays. With the Starter package at $1.00 for 4 credits, that's just $0.25 per comprehensive grade analysis.

What does the AI card grading report include?

Each report includes sub-grades for corners, edges, surface, and centering, plus an overall predicted grade, a hybrid forecast for PSA/BGS/SGC/CGC/TAG, and a visual overlay highlighting detected defects.

How does the parallel grading engine work?

Our engine overlaps the centering analysis with grade polling, and the card recognition/market data lookup with local overlay generation. This parallel execution reduces total wait time by ~40% compared to sequential processing.

How long does AI grading take?

AI grading typically completes in 22-28 seconds with our parallel engine. The animated reveal plays while results are being finalized.

Lab-grade measurement. Sub-pixel centering, microscopic corner and edge inspection, surface clouding detection — plus identification for virtually any card of any kind: sports, Pokémon, MTG, Yu-Gi-Oh!, One Piece, Lorcana and 15+ more.

📊

The full market picture. Live comps, sold listings, POPs charts, price history and per-company grading economics with ROI projections — all bundled into one report.

⚡

Every second is spent on your card. The extra few seconds are real measurement plus live market data — that's where a genuine pre-grade comes from.

💰

Spend $1 before you spend $20–50. See which cards deserve a paid submission, catch hidden flaws early, and know what your card is worth — before you ship anything.

Analytical Capabilities

The 4 Pillars of Grading

These four measurements are the grade — and the AI reads them from your photo, not from a database. That's why what you upload decides how precise the read is.

Centering

Sub-pixel border measurement for Front/Back L-R / T-B ratios.

Corners

Whitening, blunted edges, and layered paper detection at microscopic scale.

Surface

Pixel-level detection of scratches, dimples, print dots, and clouding.

Edges

Continuous scan of all borders for chipping, silvering, and rough cuts.

A better photo means a better grade

The AI can only grade what it can see. A sharp, flat, well-lit photo with the card filling the frame gives it a precise measurement of every pillar. If your photo is blurry, dark, or has glare, you'll still get full identification, market data, POPs and price history — but the grade stops where the photo evidence runs out. Your report includes an Image Quality section that shows exactly what held it back and what to fix on a retake.
