A note on AI detectors
No tool can guarantee how an AI detector will score your text. In a peer-reviewed Stanford study, seven detectors labeled 61% of human-written TOEFL essays as AI-generated on average, and independent tests have found detectors disagree with one another. Natural English you wrote — plus drafts that show your process — is the most reliable protection. Read more about why detectors flag ESL writing.
