Collectible GradeSnap

Collectible GradeSnap turns macro photos and edge/surface close-ups into sub-60-second pre-grading screening reports, centering defect heatmaps, corner/edge wear measurements, and worth-grading ROI calculators before collectors submit items to PSA, BGS, CGC, or PCGS.

### The Problem
Official grading costs €30 to €150+ per collectible item and takes weeks or months. Collectors, hobby shops, and auction marketplaces routinely waste significant money submitting raw items that have subtle micro-scratches, edge chipping, or off-center alignment that cap their grades below profit thresholds. Manual pre-screening with loupes is tedious, subjective between shifts, and yields zero reusable audit data.

### The Solution
Collectible GradeSnap combines multimodal computer vision powered by the Sensifai AI Engine with sub-millimeter centering ratios, 4-corner microscopic wear profiling, and surface scratch detection. Collectors snap front and back macro photos under guided lighting, and the system instantly delivers estimated grade ranges (e.g., PSA 8.5–9.2, Mint 9), defect annotations, and an empirical grading ROI breakdown.

### Key Capabilities
- Front/back centering ratio measurement (top/bottom, left/right sub-pixel alignment)
- 4-corner micro-whitening and edge fraying wear detection with zoom crops
- Surface print-line, foil scratching, and silvering anomaly flags
- Confidence-banded grade range prediction mapped to major grading scales (PSA, BGS, CGC, PCGS)
- Worth-Grading ROI calculator comparing raw market value vs grading fees vs slabbed upside
- Instant PDF screening certificate and exportable condition dossier
