Ready for the whole library?

Grade strings here, then scan live pages and bulk-generate with review-before-save in WordPress.

Is this a WCAG certification?

No. It is a free heuristic grader for common alt-text mistakes. Real accessibility conformance needs context, page structure, and human judgment.

Can it grade my whole WordPress site?

This tool grades one string at a time. For page-level gaps, use the free image SEO audit. For media-library bulk work, install OpptiAI Alt Text.

What does a strong score mean?

It means the text avoided common red flags (filename-as-alt, stuffing, extreme length). You still need to check accuracy against the actual image.
