Rewrite AI - Zero-AI Stealth Text Humanizer & Anti-Plagiarism Engine

Rewrite AI is an enterprise-grade text humanization and anti-plagiarism engine built on statistical entropy heuristics. It systematically deconstructs the uniform syntax, flat burstiness, and predictive n-grams of LLMs (ChatGPT, Claude, Gemini, DeepSeek), transforming robotic outputs into authentic human prose that scores 0% AI on Turnitin, GPTZero, ZeroGPT, CopyLeaks, Scribbr, and Winston AI.

Key Capabilities

• Extreme Burstiness Modeling: AI detectors detect uniform sentence cadence (15-20 words per sentence). Rewrite AI injects high variance: pairing 3-word punchy assertions with intricate 25-word multi-clause sentences.
• Perplexity Amplification: Replaces predictable LLM token sequences with natural, high-entropy human collocations without compromising meaning.
• Systematic Cliché Purge: Automatically removes recognized AI transition markers:
  • English: delve, tapestry, testament, beacon, multifaceted, crucial, paramount, moreover, furthermore, in conclusion.
  • Spanish: sumergirse, tapiz, testimonio, crucial, en conclusión, es fundamental destacar, cabe señalar, desempeña un papel.
• 1:1 Factual Fidelity: Guarantees absolute preservation of names, dates, quotes, mathematical figures, and scientific claims.
• Dedicated Modes:
  • Ultra-Stealth (0% AI): Maximum entropy disruption for strict institutional detectors.
  • Academic / Anti-Turnitin: Formal scholarly tone, thesis-grade vocabulary, and citation preservation.
  • Executive / Business: Punchy, high-impact business communication without corporate fluff.
  • Natural / Conversational: Fluid, idiomatic, relaxed human cadence.
• Real-Time Telemetry Dashboard: Live meters for AI Probability, Sentence Burstiness, Lexical Perplexity, and Purged Clichés.
• Visual Diff Inspector: 1-click side-by-side highlighter comparing modified phrasing against the raw input.
