# Humanizer — AI Writing Humanizer, Pattern Detector, and Rewriter

> Last updated: 2026-08-25 (v0.6.0). Humanizer is a pure-Markdown Claude Code skill, an AI writing humanizer, that detects 55 AI writing patterns and rewrites text with human rhythm, voice, and burstiness. 5 named voice profiles. 0-100 AI-tell score. Zero-dependency Markdown core plus an optional metrics CLI, CI gate, and pre-commit hook. No network calls, no binaries. Install in one command.

## Install

- [Any agent via the skills CLI](https://github.com/Aboudjem/humanizer-skill#quickstart): `npx skills add Aboudjem/humanizer-skill`
- [Project-scoped curl install](https://github.com/Aboudjem/humanizer-skill#quickstart): `mkdir -p .claude/skills/humanizer && curl -sL https://raw.githubusercontent.com/Aboudjem/humanizer-skill/main/skills/humanizer/SKILL.md -o .claude/skills/humanizer/SKILL.md`
- [Plugin marketplace](https://github.com/Aboudjem/humanizer-skill#quickstart): `claude plugin marketplace add Aboudjem/humanizer-skill`

## Usage

- [Basic rewrite](https://github.com/Aboudjem/humanizer-skill#usage): `/humanizer "your text"` — rewrite with the default voice
- [Detect mode](https://github.com/Aboudjem/humanizer-skill#usage): `/humanizer "text" --mode detect --score` — scan only, get a 0-100 AI-tell score
- [Voice profiles](https://github.com/Aboudjem/humanizer-skill#voice-profiles): `--voice casual|professional|technical|warm|blunt`
- [File editing](https://github.com/Aboudjem/humanizer-skill#usage): `/humanizer --file docs/README.md --voice technical` — edit a file in place
- [Aggressive mode](https://github.com/Aboudjem/humanizer-skill#usage): `/humanizer "text" --aggressive --iterate 3` — convergence mode

## The 55 AI Patterns

- [Content P1-P8](https://github.com/Aboudjem/humanizer-skill/blob/main/skills/humanizer/SKILL.md): Significance inflation, promotional language, AI vocabulary ("delve", "leverage")
- [Language and Style P9-P18](https://github.com/Aboudjem/humanizer-skill/blob/main/skills/humanizer/SKILL.md): Negative parallelisms, em dash overuse, structured list syndrome
- [Communication P19-P21](https://github.com/Aboudjem/humanizer-skill/blob/main/skills/humanizer/SKILL.md): Chatbot artifacts, sycophantic tone
- [Filler and Hedging P22-P30](https://github.com/Aboudjem/humanizer-skill/blob/main/skills/humanizer/SKILL.md): Filler phrases, uniform sentence length, comprehensive overview openers
- [Emerging P31-P43](https://github.com/Aboudjem/humanizer-skill/blob/main/skills/humanizer/SKILL.md): Treadmill effect, infomercial hooks, elegant variation
- [Craft and Forensic P44-P55](https://github.com/Aboudjem/humanizer-skill/blob/main/skills/humanizer/SKILL.md): False agency, diff-anchored writing, reasoning-chain artifacts, unicode obfuscation, argument residue, leftover hedge debris

## Science and Research

- [Burstiness](https://github.com/Aboudjem/humanizer-skill/blob/main/skills/humanizer/SKILL.md): Sentence length variation — humans vary wildly, AI averages 18 words. Detectors measure this.
- [Perplexity](https://github.com/Aboudjem/humanizer-skill/blob/main/skills/humanizer/SKILL.md): Word predictability — AI picks the statistically likely next word. Humans don't.
- [RAID Benchmark](https://github.com/Aboudjem/humanizer-skill/blob/main/README.md): Structural paraphrasing drops DetectGPT accuracy from 70.3% to 4.6% (ACL 2024)
- [HC3 corpus](https://github.com/Aboudjem/humanizer-skill/blob/main/skills/humanizer/references/patterns.md): Bilingual ~40K-pair corpus (arXiv 2301.07597) on length, vocabulary diversity, and perplexity

## Comparisons

- [vs QuillBot](https://github.com/Aboudjem/humanizer-skill/blob/main/README.md): QuillBot swaps words; Humanizer fixes structure, rhythm, and burstiness
- [vs Undetectable.ai](https://github.com/Aboudjem/humanizer-skill/blob/main/README.md): Paid, closed, no pattern detection, no voice profiles
- [Open source advantage](https://github.com/Aboudjem/humanizer-skill/blob/main/README.md): 55 patterns vs 0, 5 voices vs 3, free vs $10-20/mo, explains every change

## Optional

- [Metrics CLI](https://github.com/Aboudjem/humanizer-skill/blob/main/cli/README.md): Zero-dependency Node tool that computes burstiness, TTR, trigram repetition, AI-vocab density, and a 0-100 score, with a CI quality-gate and GitHub Action
