AI Readability vs ToolsVale Readability Checker

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.

ToolsVale Readability Checker evaluates pasted text or URLs for readability, crawler access, and paragraphs that may need revision. It combines seven readability formulas into a weighted consensus grade and reports Readability, Content Clarity, and beta AI Citation Readiness scores. Paragraphs receive color-coded scores, with difficult sentences available for inspection, and the checker provides rule-specific fixes classified as deterministic, safe-with-review, or semantic. Crawler checks fetch pages as Chrome, Googlebot, GPTBot, ClaudeBot, and PerplexityBot to flag blocked access or substantial content differences. Users can compare up to 10 URLs side by side in one run, and share reports through links available for 48 hours. The checker is free, requires no account, has no daily limit, and does not put features behind a paywall; it allows 30 checks per minute per IP address. Requests are processed on a server over an encrypted connection, and uploaded content is deleted within one hour. Because page fetching uses raw HTML, client-side JavaScript content may not appear; the site suggests pasting visible text for JavaScript-heavy pages.
