    Why AI Detectors Flag Well-Written Essays

    <p>The question assumes the detector read your essay and marked it down for reading too well. Nothing the vendor publishes about the tool has anywhere to put "well written", which changes what a flag can be telling you.</p> <h2> The short answer </h2> <p><strong>It is not grading…
