SnapGradeAI vs TAG Grading — AI pre-grade vs AI grading service.

TAG is a grading company that uses AI internally — they grade and slab your card, similar to PSA but AI-driven. SnapGrade is a pre-grading tool — you submit a photo, we predict the grade before you ship the card anywhere.

They're not the same product. Here's why that matters.

TAG replaces PSA submission. SnapGrade decides whether PSA (or TAG) submission is worth it. Different problems — and the right answer is often both.

TAG — full grading service

You ship TAG your card. They grade it with AI, slab it, ship it back. Output: a physical TAG-encapsulated card with a grade.

SnapGrade — pre-grading prediction

You upload a photo. AI predicts the PSA grade with sub-grade breakdown. Output: a digital prediction in 6 seconds.

Turnaround time

TAG: weeks (verify current). SnapGrade: under 6 seconds.

Pricing model

TAG: per-card grading fee + shipping + insurance. SnapGrade: $1–$2/card pre-grade, no shipping.

Card stays at home

TAG: ship to them and back. SnapGrade: card never leaves your hands.

Market recognition

PSA-slabbed cards carry the largest resale premium. TAG slabs are growing. SnapGrade reports aren't slabs — they're decision tools.

Are you trying to grade a card or decide whether to grade it?

TAG Grading is a card-grading company that uses computer vision to grade and slab your card. Their slab is the deliverable — similar to PSA or BGS but with AI-driven evaluation. You ship the card, you get a slab back.

SnapGradeAI is a pre-grading tool. You submit a photo and we predict the grade before you ship the card to PSA, BGS, CGC, or TAG. The card never leaves you, the prediction takes 6 seconds, and the output is a digital report — not a physical slab.

They solve different problems: TAG replaces PSA submission; SnapGrade decides whether PSA (or any other) submission is worth it. Many collectors use both — SnapGrade to screen the batch, then TAG (or PSA) on the winners.

When to choose each

Choose TAG Grading if…

Choose SnapGrade if…

Use SnapGrade first, then TAG (or PSA)

The most informed workflow: pre-grade your batch with SnapGrade first, identify the cards most likely to grade 9 or 10, and ship those (and only those) to TAG or PSA. This avoids spending grading fees on cards that won't earn back the investment.

The bottom line

TAG and SnapGrade aren't direct competitors — TAG grades and slabs, SnapGrade predicts. If you want a slab, TAG is one valid path (PSA is another). If you want to decide which cards deserve a slab in the first place, SnapGrade is the tool. The honest answer is usually "both", in that order.

Common questions

Questions we hear all the time.

Is TAG a real grading company?
Yes. TAG (Technical Authentication & Grading) is an AI-driven grading service that slabs cards. It's a smaller market presence than PSA but a legitimate grading company.
Does PSA accept TAG-graded cards for cross-grading?
PSA's policies on cross-grading from other slabbing services change periodically — verify current PSA cross-over rules before submitting a TAG slab to PSA.
Can I use SnapGrade on a TAG-graded card?
You can pre-grade any card with SnapGrade, but once a card is in a slab the SnapGrade prediction is largely academic — the official grade has already been assigned.
Which is cheaper, TAG or SnapGrade?
SnapGrade is much cheaper per card ($1–$2) because it doesn't slab the card — it predicts the grade. TAG is cheaper than PSA for grading-and-slabbing, but more expensive than SnapGrade because it produces a physical product.
