Frequently asked questions
HumanizeAI analyzes text using a combination of perplexity scoring (how predictable each word is given the preceding context), burstiness analysis (variation in sentence length), and syntactic pattern recognition. AI-generated text tends to have low perplexity and uniform sentence structure — we surface those signals in the analysis report.
