Frequently asked questions

Gemaura is an AI tool that estimates the grade of a sports card from photos of the front and back. It scores the four things graders look at — centering, corners, edges and surface — and returns an estimated grade in seconds, so you know roughly how a card would grade before paying to submit it.

Upload a clear photo of the front and back of your card. Gemaura's machine-learning model analyzes the condition factors and returns an estimated grade on the familiar 1–10 scale, along with a confidence score.

Estimates are a guide, not a guarantee. They reflect what the model can see in your photos, so lighting, photo quality and borderline cases all affect the result, and an estimate won't always match an official grade. Use Gemaura to decide whether a card is worth submitting — not as a replacement for professional grading.

No. Gemaura is an independent service and is not affiliated with, endorsed by, or sponsored by any card-grading company. References to the 1–10 grading scale describe the familiar industry standard only.

Professional grading costs money and takes time, so it only makes sense for cards likely to come back in high grade. Gemaura gives you a fast, low-cost read on a card's likely condition first, so you can avoid paying to submit cards that probably won't grade well.

There's a free plan with one estimate per month. Paid plans (Plus and Pro) add more monthly credits and grading history, and you can buy extra credits at any time. See the pricing page for current details.

Yes — you can cancel from your account settings at any time, no questions asked.

Yes. Credits never expire and accumulate — any unused credits carry over to the next month.

Monthly credits are included in your plan and stack up over time. Extra credits are purchased separately and work the same way — they all accumulate in your balance and never expire.

Gemaura works best on modern sports cards photographed clearly, in even lighting, against a plain background, with the whole card visible in frame. Blurry, angled or cropped photos lower the accuracy of the estimate.

No. A Gemaura estimate is a prediction to help you decide whether grading is worth the cost. Official grades are determined by the grading company and can differ from the estimate.
