AI Readability Checker vs Health Literacy Advisor

AI Readability Checker is a free web tool for reviewing whether pages and drafts are easy for AI assistants to extract. Users can enter a URL or paste content before publication. It examines heading structure, paragraph and sentence lengths, and how quickly a page answers its apparent topic. Additional checks assess whether headings clearly name or pose questions, each paragraph makes one point, and sentences are concise enough for clean quotation. Results separate checks into pass, warning, and fail states and provide rewrite suggestions for flagged sections. The maker connects these practices with human-friendly writing, while also favoring passages that remain understandable outside their original context. The checker measures extractability and understandability only; it does not promise selection or citation by ChatGPT, AI Overviews, or another AI product. The page describes URL and pasted-content input, without naming third-party integrations. Google reCAPTCHA protects the site, with Google's Privacy Policy and Terms applying.
