🔍

  • Score 0–100 per listing
  • 10 weighted dimensions
  • Evidence per dimension
  • Method shown (AI Vision / Detected / Estimated)
📊

  • Impact ranking per gap
  • Category-specific analysis
  • Matches actual RUFUS behavior
🧠

COSMO Semantic Score

COSMO is Amazon's computer vision model that reads listing context. Get a 0–100 score showing how well your listing answers buyer intent across 5 relationships.

  • Use case coverage
  • Target audience clarity
  • Problem-solution framing
  • Occasion context

AI-generated briefs that target your exact gaps.

🗺️

Smart Gap-Based Blueprint

Unlike tools that always suggest 7 images, Letnexus generates only the slots you actually need — 3 to 7 — based on your specific RUFUS and COSMO gaps.

  • Only generates missing image types
  • Slots named by goal not type
  • Addresses real buyer questions
🎬
