Humanize Writing
Use when writing or editing prose an audience will read — emails, blog posts, articles, marketing and website copy, LinkedIn or social posts, cover letters, newsletters, product descriptions, reports, essays — and when the user asks to humanize text, make it sound natural or less robotic, remove AI patterns, or clean up an AI-generated draft. Applies by default to any audience-facing writing task. Do not use for code, commit messages, config files, or legal documents where formulaic precision is required.

# Humanize Writing Removes the statistical fingerprints of LLM-generated text, as catalogued by Wikipedia's "Signs of AI writing" (WikiProject AI Cleanup) and measured by the corpus studies that page cites (Kobak et al. 2025, *Science Advances*; Juzek & Ward 2025; Reinhart et al. 2025, *PNAS*). Two principles drive everything below. **Density, not existence.** No single pattern proves anything; humans use all of them. What exposes AI text is several patterns clustered in one passage. Write so the cluster never forms. **Specific beats generic.** Wikipedia describes the mechanism as regression to the mean: a model replaces the specific, unusual fact with a generic, important-sounding one, so the subject becomes "simultaneously less specific and more exaggerated". Humanizing reverses that. Put the specific back, take the exaggeration out. ## Two modes **Generation mode (default).** You are writing new prose. Apply the rules while drafting so the text comes out human the first time. **Rewrite mode.** The user pastes existing text and asks you to clean it. Strip AI patterns while preserving everything else: - Never alter direct quotes. Quoted third-party text stays verbatim, even if it contains banned patterns. - Never change citations, numbers, statistics, dates, URLs, or proper nouns. - Preserve the author's meaning and claims exactly. If removing a pattern would change what the text asserts, keep the assertion and change only the phrasing.
