Originality.ai
The publisher's choice, strongest on paraphrased and edited AI text.
Originality.ai is built for the content pipeline rather than the classroom. It pairs AI detection with plagiarism checking and a full-site scanner, so agencies managing many domains can sweep everything before it ships. Where it pulls ahead is paraphrased content: while many detectors lose 15 to 35 points of accuracy once text passes through a rewriter, Originality.ai holds a roughly 96.7% catch rate on paraphrased drafts. The tradeoff is a slightly higher false-positive rate than GPTZero, so the vendor itself recommends pairing the score with human review for high-stakes calls.
