AltText.ai vs Caseo

AltText.ai generates image descriptions intended to support accessibility and help search engines understand image content. It supports more than 130 languages and can be used through its web service, integrations, browser extensions, and developer tools. Listed integrations include WordPress, Shopify, WooCommerce, Magento, BigCommerce, Contentful, DatoCMS, Storyblok, Cloudinary, Dropbox, Pinterest, and Google Drive. Developers can use a REST API, webhooks, or an MCP server; Chrome and Firefox extensions generate descriptions for web images. A free scanner checks up to 25 pages for missing alt text and reports an AI visibility score. One credit covers one image, and each additional language translation costs another credit. Standard formats include JPG, PNG, GIF, WebP, and BMP. Paid plans also support formats such as AVIF, HEIC, HEIF, JP2, SVG, and TIFF at two credits per image. Prices include a 3.00 USD one-time pack of 50 credits and annual Bronze at $49 a year. AltText.ai says submitted images are removed after processing and are not used to train AI models without expressed written consent.

Caseo is a Shopify app for generating image alt text and SEO content for online stores. Its AI uses product images together with product data to create alt text for screen readers and search engines. It can bulk-generate meta titles and descriptions for products, collections, and blog posts, and generate or revise product descriptions to match a store’s tone. Generated material can be reviewed and edited individually, or checked in bulk before it is applied. Each image alt text, meta title, meta description, or product description uses one credit, deducted when generation happens. Caseo lists English, Spanish, French, Portuguese, Italian, German, Dutch, and Lithuanian. It writes fields through the Shopify Admin API and says it does not alter theme code or affect page-load speed. The free plan includes 50 credits, a full store scan, and all features unlocked within a 15-day trial window, with no card required. One-time credit packages start at 9.00 USD; purchased credits remain valid for 365 days. A 30-day money-back guarantee applies to unused credits.
