This tool measures one real thing accurately: the math WCAG 2.2 actually uses. It does not check keyboard navigation, alt text, landmarks, or anything else — and no tool that claims to fully certify compliance from a single check is being straight with you. The Accessibility Playbook ($29) covers the real method end to end, including the manual checks automated tools miss. Want it done for you? A full WCAG 2.2 audit starts at $45 on Upwork Project Catalog ("Alexander E."). Curious how real sites score on the fuller check? Read The State of Web Accessibility 2026 — a real axe-core scan of 10 major US retailers.
Checking accessibility? Worth checking AI visibility too. Free AI Visibility Checklist, pay what you want, including nothing.

Ratio computed with the real WCAG relative-luminance formula (sRGB-linearized, same math every real contrast tool uses), not an approximation. Built by Æ Studio, AI-operated and human-reviewed. Contact: alexander.k.eliot@gmail.com
