The Problem
Collectors often rely on gut checks before listing, submitting, or trading. That can lead to poor pricing, wasted submission fees, or missed opportunities.
Built for Collectors and Sellers
The trading card grading app for faster pre-grade decisions.
Get a fast, explainable pre-grade estimate before submission or sale.
Automated estimate only. Not an official grade.
The GemScout Solution
GemScout evaluates card images for quality, analyzes visible defects, and returns an explainable estimated grade band with confidence details you can act on.
Made for real TCG grading workflows
GemScout is built as a practical trading card grading app for Pokemon grading prep, One Piece grading checks, and Yu-Gi-Oh grading reviews before listing or submission.
Use it to screen raw cards quickly, compare scans over time, and decide which cards deserve grading fees.

How GemScout Works
-
Step 1
Capture front and back photos
Frame the card cleanly and let GemScout validate capture quality before analysis.
-
Step 2
Run image quality checks
Blur, glare, exposure, and perspective checks reduce false confidence from bad scans.
-
Step 3
Analyze grading factors
Centering, corners, edges, and surface condition are evaluated together in seconds.
-
Step 4
Review explainable results
Get a grade band, confidence range, top defects, and visual overlays that show what matters.
Example Result Card
Every scan is paired with clear reasoning, confidence metrics, and visual defect highlights so you can make decisions with less guesswork.
Sample Result
Sample Result
Estimated Grade Band: 8.0 - 8.5
Top Detected Defects
- Upper-right corner whitening
- Minor edge chipping (left side)
- Slight centering offset (front)
Why This Grade
Surface remains strong with low scratch visibility, but corner wear and mild centering drift limit upside toward mint bands.
Confidence interval: +/- 0.5 grade points
FAQ
Is this an official grade?
No. GemScout provides an automated pre-grade estimate to support decisions before submission or sale. It is not an official third-party grade.
How accurate is it?
Accuracy depends on image quality, card type, and visible defects. GemScout pairs the estimate with confidence metrics so you can judge reliability scan by scan.
Does it work with holographic cards?
Yes, but reflective foils can introduce glare. GemScout flags these quality issues and may widen the confidence interval when glare affects defect visibility.
Is my data uploaded?
No by default. Processing runs on-device, and scan history is stored locally on your phone unless you choose to export anything manually.
Why do confidence scores vary?
Confidence changes with image quality, lighting consistency, and defect clarity. Better captures usually produce tighter ranges and higher confidence.
Can I compare scans over time?
Yes. GemScout keeps local scan history so you can review past captures and compare shifts in likely grade outcomes.
