Built on Trust & Transparency

We're honest about what AI can and cannot verify

What We Can Verify
  • • Set identity and model number
  • • Major visible assemblies and modules
  • • Color substitutions in visible parts
  • • Minifig presence and configuration
  • • Build correctness from visible angles
  • • Surface condition and cleanliness
  • • Sticker alignment and condition
Limitations
  • • Hidden internal parts and structure
  • • Micro-parts and small elements
  • • Visually identical substitutions
  • • Internal structure without disassembly
  • • Parts obscured in photos
  • • Authenticity of individual bricks

These limitations are clearly noted in every report with follow-up recommendations.
