AI detection FAQ
Can AI detectors detect paraphrased text?
Quick answer
Paraphrasing and humanizing tools can weaken AI-writing signals, so paraphrased text is harder to detect — but it is not guaranteed to evade detection, and the practice often raises its own integrity concerns.
Detectors look for statistical patterns in word choice and sentence structure. Paraphrasers rewrite those patterns, which can lower a detector's confidence. Some paraphrased passages still trigger signals, while others slip through, so results become more uncertain.
This uncertainty cuts both ways: it makes evasion possible but also raises false-positive risk for genuine human editing. That is why a single score should never be treated as proof when heavy paraphrasing may be involved.
Reviewers should weigh paraphrased results alongside drafts, sources, and policy. Where AI use is permitted, disclosure is simpler and safer than trying to disguise it.
