What makes AI text detectable

AI detectors analyze statistical properties: perplexity, burstiness, transitional phrase density, and sentence rhythm. AI models produce text with very low perplexity and very low burstiness.

The only reliable method: deep linguistic restructuring

Surface-level changes like synonyms and paraphrasing do not reliably make AI text undetectable. Detectors analyze statistical patterns across the entire document. The only reliable method is deep linguistic restructuring.

Using Text Humanica for undetectable output

Text Humanica's 3-stage pipeline is specifically engineered to produce undetectable output. Stage 1 identifies the highest-risk sentences. Stage 2 restructures them to maximize burstiness and perplexity. Stage 3 does a final pass to ensure naturalness.

Detector-by-detector bypass rates

GPTZero: ~96% bypass rate with Pro plan. Turnitin: ~93%. Originality.ai: ~94%. Copyleaks: ~91%. Winston AI: ~95%. ZeroGPT: ~97%. These rates are based on internal testing with 500 text samples.

Verifying your output

Always verify humanized text before submitting. Run it through Text Humanica's detector to get an AI probability score. For academic submissions, aim for below 20%.
