Pricing model
SnapGrade: pay-per-credit, no subscription, credits never expire ($2 for 1 up to $50 for 50). CardGrade.io: monthly plans from $4.99 (10 credits) to $74.99 (300 credits), with one-time packs available from $9.99.
Both predict a grade from a photo before you pay to submit. The real differences are the pricing model, how many grading companies each one predicts for, and whether either publishes a real accuracy figure you can check.
Neither replaces PSA, BGS, or CGC — both help you decide whether a card is worth submitting. The choice comes down to how you pay and how much you value a transparent accuracy number.

CardGrade.io natively predicts PSA, BGS, and CGC grades on every scan. SnapGrade predicts on PSA's 1–10 scale and maps that to BGS and CGC equivalents.
SnapGrade publishes a specific comparison figure — 87% within ±0.5 of the actual PSA grade, across 412 real comparisons. CardGrade.io's own FAQ describes its model as "developed using thousands of card images" but doesn't publish a match-rate percentage.
SnapGrade returns a result in under 6 seconds. CardGrade.io's own site states results in about 60 seconds.
SnapGrade is browser-only by design — no app store, works the same on any device. CardGrade.io offers native iPhone/iPad and Android apps billed through the App Store and Google Play, alongside its web tool.
Both cover Pokémon, sports cards, MTG, Yu-Gi-Oh!, One Piece, and more — neither is single-game-only.
SnapGradeAI is deliberately browser-only — open snapgradeai.com on any phone or desktop, no app store, no download. If you want an install-free workflow that works identically across every device, that's the main thing in SnapGrade's favor.
CardGrade.io ships real native apps (billed via the App Store and Google Play) alongside a web tool and a Chrome extension for grading cards directly on eBay, COMC, and TCGplayer listings — useful if you want a dedicated home-screen app or you shop those marketplaces often.

Both tools solve the same problem — a pre-submission grade prediction — with different business models and different distribution choices. If you want no subscription, a transparent accuracy figure, and zero installs, SnapGrade's model is built around exactly that. If you want native PSA/BGS/CGC predictions and a dedicated app, CardGrade.io's broader company coverage may fit better. Try each on a real card before committing to either.
