AI Readability Checker

Purpose: The checker scans structural and language signals that help AI assistants extract content, including headings, early answers, sentence and paragraph complexity, and standalone passages.
Input modes: Users can enter a page URL or paste draft content for checking before publication.
Page analysis: It extracts heading structure, paragraph and sentence lengths, and how early content answers its apparent topic.
Extractability checks: It scores whether headings name or pose clear questions, paragraphs make one point each, and sentences are short enough for a model to quote cleanly.
Results: The checker presents pass, warning, and fail checks plus rewrite suggestions for sections flagged as hard to extract.
Human readability: The maker says AI readability overlaps with human-friendly writing such as short sentences, one idea per paragraph, and clear headings, while also favoring passages that make sense out of context.
No citation guarantee: The tool measures extractability and understandability and does not guarantee selection or citation by ChatGPT, AI Overviews, or another AI product.
Integrations: The product page describes URL scanning and pasted-content input but does not name third-party product integrations.
Security: The product page states that the site is protected by Google reCAPTCHA and that Google's Privacy Policy and Terms of Service apply.
Support: The page invites users to leave an email so Fortitude can help fix issues holding their site back.
Intended users: The checker supports reviewing existing pages and draft content before publication for AI extractability.
Maker history: Fortitude Development says it has helped individuals, start-ups, and business owners since 2016.
