Runs On Your Storefront
A tiny 2KB script loads on your store pages and fills in alt text as images appear. Powered by our AI vision models.
How BigCommerce Alt Text Automation Works
Install from the marketplace, connect your account, activate the script, and product images start getting descriptions:
Install the App
Find AltText.ai in the BigCommerce App Marketplace and click "Get This App" to install.
Connect Your Account
Link your AltText.ai account using an API key. Create a free account if you don't have one.
Activate the Script
Click "Install InstantAlt Script" in the app to add our 2KB script to your storefront pages.
Alt Text Appears
As customers browse, the script fills in alt text for each image. They won't notice—but Google will.
Key Features for BigCommerce Stores
Built for BigCommerce's product structure, themes, and variant system:
Uses Your Product Data
The alt text includes your product names and brands, plus colors and details our AI sees in the images. So Google sees "Nike Air Max 90 in white and grey" instead of just "a sneaker on a white background."
Handles All Your Images
Main product photos, variant images, gallery shots—the script catches them all. Product pages, category grids, search results, wherever.
Works With Any Theme
Cornerstone, custom themes, headless setups—doesn't matter. The script runs on your storefront and handles images regardless of how your theme is built.
No Batch Jobs
Upload a new product and it gets alt text the first time someone views it. You don't need to run bulk processing or wait for anything to sync.
Multilingual Support
BigCommerce supports multiple storefronts and currencies—your alt text should match. We generate descriptions in 130+ languages for localized product pages.
Accessibility Support
Screen reader users can actually navigate your catalog. Meets WCAG 2.1 Level AA standards.
Why Bother Writing Alt Text Manually?
Writing Alt Text by Hand
- 500 products with 4 images each = 2,000 descriptions to write
- Variant images double or triple the workload
- Quality drops when rushing through bulk updates
- New inventory arrives without descriptions
With AltText.ai
- All 2,000 images handled as visitors browse
- Variant images get unique descriptions based on what the AI sees
- Consistent tone and style across every product
- Fresh products get indexed right away

InstantAlt is a 2KB JavaScript snippet that runs on your BigCommerce storefront. When someone views a product, it grabs alt text from our servers and adds it to the image. Takes milliseconds and doesn't slow down your pages.
-
Yep. Each variant image gets its own description. A blue shirt looks different from a red shirt, so they get different alt text. The AI describes what it sees in each photo.

Regular formats like JPG and PNG cost 1 credit per image. SVG and AVIF cost 2 credits because they're more complex. You get 25 free credits to start. Volume discounts kick in for larger catalogs.
