Use when reviewing web pages, dashboards, blog posts, page titles, meta descriptions, copy baked into JavaScript by a coding agent, or the text of a PDF document. Checks HTML, Markdown, plain text, rendered JavaScript string literals, PDF text and Word or OpenDocument document text only; it is not a code-quality, accessibility, security or SEO linter (those run only as explicit opt-in audits) and it does not judge whether a claim is true.
