AI Readability Checker vs Text Inspector

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.

Text Inspector analyses English text for difficulty, readability, lexical diversity, and CEFR levels. Its overall difficulty score draws on more than 200 metrics, while the CEFR Level Checker gives individual words a level along with their commonness and difficulty. Listed tools include Statistics and Readability, Lexical Diversity, Scorecard, Tagger, EVP, BNC, COCA, Academic Word List and Phrases, Knowledge-Based Vocabulary Lists, and Metadiscourse Markers. An API lets people and organisations add analysis and scoring to their own products. The maker describes it as useful to language professionals, academics, and students preparing teaching materials or tests and evaluating student work. English is fully supported; other languages may receive limited statistics or lexical-diversity information. The Free plan covers 250 words and automatically deletes analysis data after six hours. The Organisation plan allows up to 13,000 words, the largest stated limit. A 30-day trial is listed for API access, which starts from £360 per year.
