CaveatThese signals are probabilistic proxies, not proof of authorship.
False positives and false negatives are unavoidable at every threshold, so a score should never be
sole evidence in an academic, employment, or disciplinary decision. Real detectors estimate perplexity
with a language model; this page uses transparent heuristics, but the failure modes are shared.
