What is the Free AI Readability Checker?

The Free AI Readability Checker measures how easily AI models can extract answers from your page. It scores heading hierarchy, answer-first (BLUF) formatting, paragraph and sentence shape, semantic HTML, and entity clarity — the signals that decide whether an AI engine can quote you. Your report is emailed to you.

What the Free AI Readability Checker checks

  • Heading hierarchy — a single H1 and logical, unskipped H2–H4 nesting
  • Answer-first (BLUF) formatting so key answers appear early
  • Paragraph and sentence length for clean AI extraction
  • Semantic HTML — article, section, nav, main, header, footer
  • FAQ and “what is” entity statements AI models quote
  • Descriptive alt text and meaningful internal-link anchors

Frequently asked questions

What is AI readability?

AI readability is how easily a large language model can parse your page and extract a clean, quotable answer. It depends on heading structure, answer-first formatting, concise paragraphs, and clear entity statements.

Why does BLUF formatting matter for AI?

BLUF — Bottom Line Up Front — puts the direct answer at the top of a section. AI engines preferentially extract early, self-contained answers, so BLUF content is more likely to be cited.

Is this the same as a Flesch reading score?

No. Classic readability scores target human reading level. This tool measures machine extractability — structure, semantics, and answer formatting — which is what determines AI citation.

Is the Free AI Readability Checker really free?

Yes. You can scan a website at no cost and receive the full report by email. There is nothing to install and no credit card required.
