AltKing: AI Alt Text SEO & ADA vs AltText.ai (2026): which should you pick?

Pick AltKing: AI Alt Text SEO & ADA if

• Fits if your Shopify catalog has hundreds of product images with no alt text
• Works for stores that already use StarApps' Variant Image Automator

Look elsewhere if

• Skip it if your store isn't on Shopify, as it installs only from the Shopify App Store
• Watch out: despite AI in its name, the listing describes alt text built from templates, not written by AI
• Too light for meta tags, schema, sitemaps or redirects, as it covers product image alt text only
• Watch out: variant details in alt text need Variant Image Automator, another StarApps app
• Watch out: the listing links no help center or FAQ, so questions go to StarApps support

Pick AltText.ai if

• Fits if your store or blog has hundreds of images with no alt text
• Works for multilingual sites that need alt text in several languages

Look elsewhere if

• Tight if you're just looking, as the 25 free credits are one-off and packs cost $3 for 50
• Pricey if you have lots of images, as 2,000 a month is $59 and 10,000 is $229
• Watch out: AVIF, HEIC, SVG and TIFF cost 2 credits and need a paid plan, and each extra language is 1 more
• Watch out: changing plans forfeits that period's unused credits, and used credits are usually not refunded
• Too light for your whole SEO setup, as it only writes alt text
