Proofmark checks a document before you whether your sources exist, whether they still resolve, and whether they say what you cite them as saying. And whether the prose is clean. Built for students, academic researchers, consultants, corporate and enterprise professionals, journalists, and authors who stand behind their own names.

Your document stays in your browser. Only the reference strings and passages you confirm are sent, and the passages are discarded in the same request. Before anything is sent, you see the exact strings and confirm them.
Inline links, footnotes, endnotes, and unlinked attributions. Each linked source is fetched and checked against what you cite it as saying. A citation without a link is flagged for you to add one. Every result carries dated evidence of what was found and what could not be established.
Strunk (1918), Orwell, and Flesch readability, plus our own named checks, evaluated locally with zero outbound requests.
