The shortest fair summary: Ludex is for cataloging your collection by camera; SnapGrade is for deciding which cards to ship to PSA.

Ludex — card identification

Strong at recognizing cards from photo (set + variant + estimated value). Condition flags are binary tags rather than sub-grade predictions.

SnapGrade — PSA pre-grading

Pricing model

Ludex: subscription tier (verify current rates). SnapGrade: pay-per-credit, $1–$2/card, 2 free on signup, never expires.

Verified accuracy data

SnapGrade publishes a 412-card public log of prediction vs PSA return. Ludex hasn't (at time of writing) published a comparable verification dataset.

Shareable reports

SnapGrade reports have public URLs (snapgradeai.com/r/...) for eBay listings. Ludex collections are app-internal.

Mobile model

Ludex: native iOS + Android apps. SnapGrade: web app, no install needed, runs in mobile browser with camera viewfinder.

What does each tool actually do?

Ludex is an AI mobile app that identifies trading cards by photo and flags visible condition issues. It's primarily a cataloging tool — point your camera at a card, get back the set/variant/estimated raw value, and add it to your collection.

SnapGradeAI is an AI pre-grading service that predicts the PSA grade your card will receive, with sub-grade breakdown and confidence-based refunds. The output is a predicted PSA grade with reasoning — designed for the question "should I submit this card to PSA?"

The two solve different problems. Many serious collectors use both — Ludex to ingest the collection, SnapGrade to decide what's submission-worthy.

Accuracy & verification — the key difference

SnapGrade publishes 412 verified PSA returns with predicted vs actual grade for every card — including the cards we got wrong. Across that dataset: 87% within ±0.5, 89% on Pokémon specifically, 96% within ±1.0.

Ludex (at time of writing) hasn't published a comparable verified-returns dataset. The team makes accuracy claims for the identification model but the condition-flag accuracy isn't documented against PSA outcomes. If verifiable accuracy matters to your workflow, this is the cleanest single differentiator.

Choose SnapGradeAI if…

Use both if…

You have a large collection AND submit to PSA regularly. Catalog with Ludex; pre-grade submission candidates with SnapGrade. The tools are complementary, not substitutes.

The bottom line

Ludex is the better tool if your primary job is "what is this card and what's it worth?". SnapGrade is the better tool if your primary job is "is this card worth $42 in PSA fees?". The 412-card verified-returns log is the cleanest reason to trust SnapGrade on the second question.

Is SnapGrade or Ludex more accurate for Pokémon cards?
