What it does

AI Text Auditor scans text you paste in and reports which of 28 patterns associated with AI-written prose are present. The report gives each finding a severity level with fix suggestions, plus an overall AI risk score, a sentence-variation figure (shown as Sentence CoV), word count and AI vocabulary density. An option highlights AI-style vocabulary in the text. The site says the analysis runs in your browser. Agents and scripts can also post text to a JSON endpoint and get back the risk score and findings; the API is rate limited to 60 requests per hour per IP address. The page sits among a set of free developer tools from the same site, which also lists an AI humanizer, an AI prose improver and a CLAUDE.md writer.
