phy-content-humanizer-audit — AI Content Signature Detector

LinkedIn's 360Brew algorithm penalizes AI-detected content with 30% less reach and 55% less engagement. This tool tells you exactly which linguistic signals are triggering detection — so you fix only what's wrong instead of rewriting everything.

Not a humanizer. An auditor.

The Problem

You draft a LinkedIn post (maybe with AI help), publish it, and reach tanks. Why?

LinkedIn's 360Brew uses an LLM to evaluate:

• Lexical diversity — AI repeats vocabulary patterns
• Sentence rhythm — AI maintains unnaturally consistent sentence lengths
• Transition words — AI overuses "Furthermore", "Moreover", "Additionally"
• Hedging language — AI says "arguably" and "it seems" instead of stating opinions
• Formality — AI avoids contractions ("do not" instead of "don't")
• Impersonality — AI rarely uses first-person pronouns
• No questions — AI makes statements, doesn't ask
• Vagueness — AI uses abstract language with no specific data
