Originality.ai is the AI detector that SEO agencies, content marketing teams, and freelance writing platforms use most. The tool's classifier is tuned for web content, which means different signals and different blind spots than Turnitin or GPTZero.
How Originality.ai scores web content
Originality runs a transformer classifier trained on a mixed corpus of human-written articles and AI-generated marketing copy. The output is a 0-to-100 confidence score where higher means more likely AI. Most agencies set their internal threshold around 30: anything above gets flagged for editor review.
Originality is particularly sensitive to the patterns of AI marketing copy: H2-H3-bullet structure, hook-promise-list-cta paragraph shape, transition phrases, and a vocabulary skew toward industry buzzwords.
