Humanization

Humanization is the umbrella term for modifying AI-generated content so it scores as human on detection tools. For text, that means raising perplexity and burstiness, removing telltale phrases, and shifting stylometric ratios. For images, it means adding sensor noise, breaking frequency-domain signatures, generating realistic EXIF, and stripping watermarks.

Humanization is not the same as paraphrasing. Paraphrasing changes wording but leaves the underlying statistical signature intact — detectors that score perplexity will still flag it. Effective humanization targets the actual signals classifiers use.

SynthGuard's humanization is layer-based and deterministic. Each layer addresses a specific signal: contractions for stylometry, phrase-replace for n-gram overlap, restructure for burstiness, punctuation for surface variation, optional unicode for last-mile evasion. The same input plus same settings produces the same output, which matters for workflows that need predictability.

Browser-only execution means humanization happens on your device. Nothing uploads, nothing logs, nothing trains on your content.
