The Science

Why synonym swappers get caught

AI detectors don't look for specific words — they analyze statistical patterns. Perplexity measures how predictable the word choices are. Burstiness measures sentence length variation. Tools like Humanizer.io reorder words but don't change these underlying patterns. Ours does.
