In their own words
AI Readability
AI Readability is a web checker for English text aimed at writers, editors, and content teams. It measures how readily people can read text and how easily AI systems can parse and reuse it. The checker returns a score from 0 to 100 covering Sentence Clarity, Structural Organization, Entity Consistency, and Answer Readiness. It also offers a short illustrative rewrite, rather than a complete edit. Scoring runs entirely in the browser, so pasted text is not sent to a server during the check. The site says the tool uses transparent heuristics without a model call, server, or crawl, and requires no signup. English is the only supported language. Selecting “Continue in Textorum” sends the text to Textorum through the URL. The maker describes the score as a proprietary diagnostic framework, not a validated scientific instrument, and says no readability tool can promise citations or rankings. The free plan costs nothing.
