What Sets SupWriter Apart From Other Extensions
Not all AI humanizer extensions are created equal — here's why SupWriter leads the category
Deep Pattern Rewriting vs. Synonym Swaps
Cheap extensions just replace words with synonyms. SupWriter rewrites sentence cadence, paragraph rhythm, and vocabulary distribution — the actual signals that Turnitin and GPTZero analyze.
Dual Humanizer + Detector in One Extension
Other tools make you install separate extensions for humanizing and detecting. SupWriter bundles both into a single lightweight extension — humanize, then verify, all in one popup.
Handles Every AI Model's Fingerprint
ChatGPT, Claude, Gemini, Copilot, and Llama each leave distinct patterns. SupWriter identifies which model generated your text and targets its specific detection signatures.
Always Up-to-Date Against New Detectors
When Turnitin releases a new algorithm or GPTZero improves its model, SupWriter's engine is updated within days — not months. Your extension always stays ahead.
