Discover the core linguistic metrics and workflow features that make our originality checks highly reliable.
Perplexity measures how predictable a word is within a sentence context. AI generators write by picking the mathematically most likely next word, resulting in extremely low perplexity. Human writers express ideas with higher variation, resulting in natural spikes in word perplexity.
Burstiness measures the variation in sentence structure and length throughout a document. AI text tends to have uniform sentence lengths and standard rhythm, resulting in low burstiness. Human writers naturally mix short punchy sentences with longer complex clauses, creating high burstiness.
