How it sells itself

AltShot 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.

ImageBoost SEO helps merchants manage and optimize store images from one place. Compress and rename images individually or in bulk, with all changes reversible and securely backed up for 30 days. Scan products to detect missing or unoptimized alt text and generate alt text using templates or AI.

Key points
  • 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
  • Image compression and SEO friendly file renaming for faster-loading pages
  • AI powered alt text generation
  • Automatic 7-day scans to catch SEO and image issues
  • Fully reversible edits with secure 30-day backups

How Shoplist compares apps

Store counts come from Shoplist’s crawl of Shopify storefronts, which detects the apps each store runs; they are as of Oct 13, 2026. Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
