How AI Detectors Work: Perplexity & Burstiness

Burstiness (Sentence Rhythm)

Humans write with natural rhythmic variation — alternating short, punchy statements with sprawling complex sentences. AI outputs uniform 14-18 word sentences with steady rhythm.

Perplexity (Word Predictability)

Large Language Models pick statistically probable next tokens, creating predictable text with signature transition phrases ("delve into", "tapestry", "in conclusion", "crucial role").
