Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureAltShot uses Google Gemini AI vision to analyze your product images and generate accurate, SEO-optimized alt text -- not templates like "Blue Sweater - Size M", but real descriptions like "Navy oversized knit sweater styled on a cobblestone street in autumn". Scan your entire store in seconds, review AI suggestions, edit inline, and apply with one click. Compress images to WebP for faster page loads.
ShelfShot processes product images directly in your browser. The editing engines run on your own device, and finished images are saved straight to your store's files - your photos are not sent to our servers for processing. The catalog audit checks every product image for five common problems: images that are too small, images that are not square, oversized files, legacy formats, and missing alt text.
- AI-powered alt text that describes what's actually in your images
- One-click scan and fix for every product image in your store
- Image compression to WebP that replaces originals and keeps your alt text intact
- Per-image SEO scores so you can see exactly which products need attention
- Every tool runs in your browser - images never leave your device
- Catalog audit with one-click links from finding to fix
- Bulk alt text, WebP, square-fit, upscale, white background
- Deterministic SEO alt text from your product data
