Alt Audit vs Caseo

Alt Audit generates AI alt text, scans websites for missing or weak image descriptions, and exports accessibility reports. Its site audits inspect real pages, extending checks beyond individual image uploads. The service says Google Gemini 2.5 Flash generates context-aware text; it describes its image checks as aligned with WCAG Level A requirements and says output meets WCAG 2.2 standards. Reports can be exported as PDFs and summaries for clients, stakeholders, or content teams. A WordPress plugin can create text when images are uploaded and process existing media-library images in bulk. Users can create API tokens from the dashboard for integrations. Each image uses one credit, subscription credits reset monthly, and unused credits do not roll over. Alt Audit says images are accessed temporarily by URL and discarded after processing, while image URL references and generated alt text are stored. The Free Starter plan includes 25 credits per month. Paid plans start with Starter at $5 a month for 800 credits; Pro is $19 a month for 3,000 credits, and Agency is $49 a month for 8,000 credits and API access.

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.
