AltMaster: AI Alt Text SEO

AltMaster helps Shopify merchants fix missing, blank, or messy image alt text at scale. Scan your store, then bulk-generate alt text with AI or reusable templates built from product title, variant, vendor, type, and tags. Preview before saving, then update product, variant, and collection images directly in Shopify. Great for large catalogs, variant-heavy stores, and migrations where old alt text needs cleanup.
