AI Readability Checker vs ProfText

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.

ProfText checks documents for vague language, patterns associated with AI-generated writing, and academic citation validity. Available on the web and through an API, it accepts text and offers a free tier with 30 clarity and detection rules. ProfText says free analysis runs in a browser Web Worker, so text stays on the user’s device and is not retained. The free plan allows unlimited analyses of up to 5,000 characters each, but excludes citation verification, AI rewrites, compliance checks, risk scoring, and shareable report links. Pro costs €9.99 per month and raises the analysis limit to 100,000 characters. It adds citation cross-checks against OpenAlex, rewrites with tone controls, compliance flags, risk grading, custom rules, and.txt and.docx uploads. Pro also includes CSV export, priority support, and report links that remain available for 90 days. Enterprise adds REST API access, bulk processing, SSO and team management, and dedicated support at a custom price. The site describes team workflows with roles, document versioning, comments, approvals, and analytics.
