Study 2: The Effectiveness of Software Designed to Detect AI-Generated Writing: A Comparison of 16 AI Text Detectors
According to this comprehensive study on “The Effectiveness of Software Designed to Detect AI-Generated Writing,” where 16 AI text detectors were evaluated, Originality.ai demonstrated remarkable accuracy identifying AI-generated content. It ranked as a top performer across GPT-3.5, GPT-4, and human-written papers with an overall accuracy of 97%.
(% of all 126 documents for which each detector gave correct, uncertain, or incorrect responses)
Top Performers: Originality.ai, Copyleaks, TurnItIn
Dataset: 126 short papers/essays that were generated by AI or first-year college students.
Evaluation Criteria: Overall accuracy, accuracy with each type of document, decisiveness, the number of false positives, and the number of false negatives.
Six common AI content detectors and four human reviewers were employed to differentiate between the original and AI-generated articles. Originality AI emerged as the most sensitive and accurate platform for detecting AI-generated (including paraphrased) content.
