See every featureAltGenius writes alt text for your product images from a template you choose, using details such as title, type, brand and variant. You see the result on your own products before you start. By default it fills in only images with no alt text, so anything you wrote stays as it is. Alt text with links or embed code, which review and video apps use, is skipped.
SEO Vision AI checks your catalog for product images without alt text and shows how many need attention. With one click, AI looks at each main product image, writes a short descriptive alt text based on what it sees and on the product title, and saves it to your store.
