Visual annotations show the analysis step-by-step
Build your grading expertise with each assessment
No expensive classes needed - AI is your teacher
See Everything We See
"Tell me why" shouldn't be met with silence. Tier 1 says "It's a 7" with zero explanation. Glass box grading shows you everything.

Corner analysis with visual highlights showing wear
Surface defect mapping with confidence scores
Verify every assessment yourself - no "trust us" required
The Card Grading Industry Has a Problem
❌ Black Box Mystery
"It's a 7" - no explanation. Can't verify. Can't challenge. Just trust them.
❌ Damage & Theft Risk
Mail your irreplaceable cards. Wait 2-3 months. Hope they don't get scratched, lost, or counterfeited.
❌ No Education
Want to learn how grading works? Too bad. Industry keeps grading mysterious to maintain their gatekeeping power.
❌ Conservative Grading
Incentive to grade low so you resubmit hoping for better. They profit from your uncertainty.
Real Story: Collector sent pristine card expecting Tier 1 10. After 3 months, it came back damaged at grade 7. Tier 1 had his card for months, charged $25, and destroyed hundreds of dollars in value. No recourse. No accountability.
This is why photo-based grading matters. Your cards never leave your possession.

Why You Can Trust AI Grading
We don't ask you to "just trust us." Here's exactly how our AI works, what it's trained on, and why it's getting more accurate every day.
Trained on Real Graded Cards
Our AI has analyzed thousands of professionally graded cards from Tier 1, Tier 2, and Tier 3. It learns patterns that even experienced graders might miss.
5,000+ training images of Tier 1-graded cards (grades 1-10)
Sub-pixel precision for centering measurements (0.1mm accuracy)
Multi-factor analysis - corners, edges, surface, centering all evaluated separately
Continuous learning from every new scan and collector feedback
Real Validation Data
We test our AI against professional shop assessments and publish the results. No hiding behind vague claims.
Ongoing validation studies comparing AI to professional graders
Target: 70-85% accuracy within 1.0 grade of professional assessment
Public accuracy reports - see exactly where AI agrees/disagrees with Tier 1
Live calibration - model improves weekly based on new data
Confidence Scores Built In
Our AI tells you when it's uncertain. Unlike Tier 1's "trust us" approach, we show confidence levels for every grade.
Grade range estimates - "85% confident this is 8.5, could be 8.0-9.0"
Visual uncertainty maps - see where AI is most/least confident
Flagged edge cases - AI warns when card is borderline between grades
Honest limitations - we tell you when professional grading is recommended
