The Rise of Detection Tools
As AI writing tools gained popularity, detection software emerged to identify synthetic text. Tools like Turnitin, GPTZero, and Originality attempt to classify whether a passage was written by a human or a machine.
The Reality of Detection Accuracy
AI detectors do not "know" who wrote a piece of text. Instead, they calculate statistical likelihoods. Because many human writers naturally write in a clear, straightforward style, detectors often flag authentic human writing as machine-generated.
