NuGrade helps comic collectors assess raw books from guided photos and videos. Capture your comic with step-by-step guides, then receive an AI-assisted condition report with a 10-point grade estimate and supporting evidence. Keep your book with you throughout the process. WHAT YOU GET • A grade estimate with a plausible range and condition notes. • Area-by-area observations covering the covers, spine, corners, staples, and pages. • Defect citations linked to the photos or video frames that informed the report. • A shareable report URL, report ID, QR code, and downloadable PDF. • Report history saved to your account. HOW IT WORKS 1. Sign in with email or Apple. 2. Buy grading credits in the app. One credit covers one comic grading submission. 3. Follow the guides to capture the covers, corners, centerfold, spine video, and flip-through video. 4. Answer a short condition survey and submit your captures. 5. Open your completed report to review the grade estimate and evidence. Processing time varies.
