ALTification vs Caseo

ALTification is a WordPress plugin and web service that uses AI to generate keyword-aware alt text, captions, and descriptions for images. It considers the page’s surrounding content and SEO context, and supports bulk site scans as well as targeted scans of pages, posts, and public custom post types. Supported formats include JPG, PNG, WebP, and AVIF. Integrations include Yoast SEO, Rank Math, All in One SEO, SEOPress, The SEO Framework, WooCommerce, and Advanced Custom Fields. Agency workflows can use before-and-after reports. One credit covers a generation; requesting alt text, a caption, and a description together can use up to three credits per image. The free trial includes 25 credits, three Preview & Refine tests, and one site. Monthly and one-time credit packages are available. Each API key is tied to the first WordPress site where it is used, so additional sites need separate keys. ALTification is operated by A Fine Studio in the United Kingdom. Its privacy policy says submitted images, prompts, and responses are not kept after generation and are not used to train AI models.

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.
