Readable by your users — and the AI that now reads for them.

AccessKnight scans any website for both WCAG 2.1 accessibility and AI readability, then hands you one report — and the shared fixes that satisfy screen readers and the AI engines (ChatGPT, Perplexity, Google AI) that now read and cite the web.

On accessible sites, AI agents finish 78% of tasks — when accessibility breaks, that drops to 42%. (UC Berkeley × Michigan, CHI 2026)

The Shared Core

Fix it once. Win twice.

Accessibility and AI readability are the same discipline — semantic structure a machine can parse. A real <button>, headings in order, alt text, server-rendered content, and clean structured data help a screen reader and an AI engine equally. AccessKnight scores both and leads every report with the fixes that count twice.

Semantic HTML first — we won't tell you to sprinkle aria-labels everywhere. Misused ARIA makes sites worse for both audiences.

Three steps to accessible.

Built on the standard
every accessibility law references.

AccessKnight runs 30 automated checks against WCAG 2.1 — the technical baseline that ADA, Section 508, EN 301 549, the EAA, and most other accessibility regulations point to. A scan gives you the WCAG evidence those frameworks ask for.

AccessKnight is an audit tool, not a legal opinion. It surfaces WCAG issues and fix guidance — consult counsel for framework-specific conformance sign-off.

FAQ

Questions, answered.

What is AI readability?
AI readability is how easily AI engines like ChatGPT, Perplexity, and Google AI can crawl, read, and cite your page. AccessKnight scores it across AI crawler access, semantic structure, and how extractable your content is.
Do the accessibility and AI fixes really overlap?
Yes. Semantic HTML, heading order, accessible names, server-rendered content, and structured data improve both scores at once. AccessKnight leads every report with these shared-core fixes — fix once, win twice.
Which AI engines does it check?
AccessKnight checks crawler access for OpenAI's OAI-SearchBot (ChatGPT search), ChatGPT-User, Anthropic's Claude, PerplexityBot, and Googlebot — plus whether your content is structured for citation.
Does this replace my WCAG audit?
No — it includes it. AccessKnight runs a full WCAG 2.1 accessibility scan (30 rules across nine categories) and adds the AI-readability score alongside it, in the same report.
Will adding ARIA improve my scores?
Usually the opposite. Misused ARIA increases errors for both screen readers and AI. AccessKnight rewards native HTML elements first and recommends ARIA only where native elements genuinely fall short.
Is AI readability included on the free plan?
The WCAG accessibility scan is free. AI-readability scoring is on the Pro and Agency plans, which scan live URLs — the AI checks need a real page, robots.txt, and sitemap, so they can't run on pasted HTML.
