Letnexus is the only tool that diagnoses your visual gaps, generates targeted briefs, and creates AI listing images — in one workflow.
Gemini AI analyzes all 9 listing images across 10 visual dimensions — hero image, infographics, lifestyle, size reference, trust signals, and more.
See exactly which buyer questions RUFUS can't answer from your images. Each gap ranked high/medium/low by conversion impact.
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.
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.
5-scene Sponsored Brand Video storyboard with hook, strategy, keyframe prompt, and Veo animation instructions for each clip.
Blueprint briefs are tailored to your product category — medical scrubs get different lifestyle guidance than pet products or supplements.
Upload 3–6 reference photos. AI extracts your product's exact shape, colors, materials, textures, logo placement, and distinctive features — locked for every generated image.
Generate hero shots, lifestyle images, infographics, size references, and trust images using Gemini's most advanced image model.
Set your brand colors, typography style (6 options), and brand mood (8 options). Both auto-suggested based on your product category.
Generate 16:9 widescreen keyframe images for each video scene — brand-locked, product-accurate, and cinematic.
Animate keyframes into 6-second video clips using Google's Veo 3.1 — the most advanced video generation model available.
All video output meets Amazon Sponsored Brand Video specifications: 1920x1080px, MP4, H.264, max 500MB, 6–45 seconds.
Every scan is saved. See your VAS score progression over time — 36 → 72 → 85 — as you upload better images and rescan.
Manage all your scanned ASINs in one dashboard. See generated images, videos, scores, and quick actions for every product.
Works with any Amazon.com ASIN. No Seller Central login, no API connection, no permissions required.
