How undetectable AI works
Detectors flag text that is too predictable, measuring signals like low perplexity and even sentence length. Humanizers paraphrase the input to add the variation and irregular rhythm typical of human writing, often looping through a detector until the score drops. Because both sides use models, results shift as detectors update, so no tool guarantees a pass forever.
