1. The Mathematics of AI Detection: Perplexity & Burstiness
AI detection engines (like GPTZero, Winston AI, and platform classifiers) analyze two primary statistical metrics:
1. Perplexity (Word Predictability)
LLMs always choose the mathematically most probable token. When text is too predictable, perplexity is low, instantly flagging the content as synthetic.
2. Burstiness (Sentence Rhythm)
Humans vary their sentence lengths dramatically: a 4-word punch, followed by an explanation, followed by a bullet point. LLMs produce uniform 16-word paragraphs.

Frequently Asked Questions
What is the primary indicator of AI-generated content on LinkedIn?
Uniform sentence length and high density of cliché transitional adjectives (e.g. 'delve', 'testament', 'tapestry', 'holistic', 'synergy'). Human writing naturally has high burstiness (mixing short 3-word sentences with longer 18-word sentences).
How does Voicewire eliminate AI detection markers?
Voicewire runs deterministic regex and phonetic filters that strip over 80 known LLM cliché phrases and reformats text with conversational single-sentence pacing.
