The short verdict
Originality.ai is one of the more reliable AI detectors for web content, combining AI detection with plagiarism and readability checks.
Our Originality.ai review
Aimed at publishers and agencies, Originality.ai scans content for likely AI generation, plagiarism and factual issues, and can scan a whole website. It is pay-as-you-go or subscription based.
