What AltKing can do
Automatically generates alt text for all product images using AI
AltKing uses AI vision models to automatically generate descriptive, high-quality alt text for every product image in your store. Each alt text is generated from the actual image content along with the product and variant properties, making it specific to each image rather than generic.
Analyzes your store before making any changes
When you first set up the app, it analyzes your store by fetching all your products and images. Before anything is published, you can preview the AI-generated alt text for your top 5 products, so you can see exactly what the output looks like before committing to it. No changes are made to your store during this preview stage.
Runs on a 24-hour schedule
The app checks your store every 24 hours for any new images that have been added or any images that still need alt text generated. Your store stays up to date automatically without any manual intervention — new products and images are picked up on the next scheduled run.
Lets you review before publishing
If you would rather approve each suggestion yourself, switch on Review alt text before publishing in App settings. Suggestions then wait on the Review alt text page, where you can edit the wording, approve the ones you want, and remove the ones you do not. Nothing reaches your store until you approve it.
Gives you full coverage visibility
Once the app is running, the dashboard gives you a complete picture of your alt text coverage across your store:
Total number of images in your store
Number of images with alt text generated
Number of images pending generation
Your overall alt text coverage

Protects alt text you have already written
By default, AltKing only fills in images that have no alt text — anything you have already written is left untouched.
For finer control, you can add exception patterns. The app checks each pattern against the image's existing alt text, and skips any image whose alt text contains one of them. Two things to know: matching is case-sensitive, so the pattern featured will not match alt text reading Featured hero shot; and an image with no alt text is never excluded, since patterns only ever protect text that is already there.
A set of default patterns ships with the app, so common exceptions are handled out of the box.
Adds nothing to your storefront
AltKing works entirely inside your Shopify admin. It installs no app embed, no theme extension and no scripts. It reads your products and writes the alt text field through Shopify's own API, so it cannot affect how your store loads or looks — and removing it cannot break your theme.
The alt text it writes lives on Shopify's own media records, so you can see and edit it in your Shopify admin exactly like alt text you typed in by hand.
Free, with no limits
AltKing has no subscription, no usage charges and no image quota. A store with 500,000 images is processed on exactly the same terms as one with 5.
Significantly enhances SEO
Because every product image gets a descriptive, variant-aware alt text generated from actual image and product data, your store's SEO improves meaningfully. Search engines use alt text to understand and index images — having accurate, detailed alt text across all your product images makes them more likely to appear in image search results and improves your overall store discoverability.
What AltKing cannot do
It does not generate alt text for non-product images
AltKing only processes images in the media section of your Shopify products. It does not generate or update alt text for other images on your store — such as images in your theme, blog posts, pages, or any other sections outside of the product media library.
It does not touch archived products
The app covers images on your active, draft and unlisted products. Archived products are skipped entirely.
It does not let you pick individual products
AltKing works across your whole catalogue rather than product by product, so there is no way to select specific products for generation. If you want control over what goes live, switch on Review alt text before publishing and approve only the images you want.
It does not support custom templates or text patterns
The app generates alt text purely using AI based on the image and product properties. It does not support building alt text from a template — adding custom metafields, static variables, or manually defined text patterns such as a product title followed by a SKU is not possible today. This may be considered for a future release — reach out to our support team if this is something you need.
The one thing you can control is the output language, in App settings → AI alt-text language.
It does not rename or change image file names
AltKing only updates the alt text attribute of your product images. It does not rename, modify, or change the file names of your images in any way, and it does not touch any other product field such as titles, descriptions or SKUs. Your media file names remain exactly as they are in Shopify.
