Introduction
Artificial intelligence is having a profound impact on the way content is created, shared and consumed in the ever-changing digital world.

Whereas plagiarism detection tools contrast submitted text against published content online, AI detectors analyze elements including structure, syntax, creativity, repetition and predictability — characteristics that can vary between human-authored and machine-authored text.
