How AI Detection Works

AI text is highly predictable. Detectors measure how "surprising" each word choice is. Human writing scores higher.

Humans vary sentence length naturally: short punchy sentences mixed with long complex ones. AI tends to be uniform.

Certain phrases, transitions, and structural patterns are strong AI signals. Detectors look for these fingerprints.
