Key Use Cases
Copyleaks provides a detailed analysis for both plagiarism and AI-generated text, making it a useful tool for academic and content integrity. However, AI detection is based on probability, not certainty. False positives on human writing are possible, especially for non-native English speakers, so a score should never be the only reason for an accusation.
