Humanize Writing Skill

Humanize Writing

A prompt-based writing editor that rewrites AI-generated text to sound like a real human wrote it.

It catches the patterns that make AI writing obvious — the vocabulary, the sentence structures, the too-perfect tone — and fixes them through a systematic 3-pass editing process.

Works with any LLM: Claude, ChatGPT, Gemini, Cursor, Windsurf, or anything that accepts a system prompt. Also available as a one-command install for Claude Code users.

How It Works

The system runs your text through three passes:

Pass 1: Kill the AI Vocabulary — Replaces words like "delve," "leverage," "tapestry," and 30+ other statistically overused AI words with simpler human alternatives.

Pass 2: Break the AI Structures — Eliminates structural patterns like parallel negation ("Not X, but Y"), tricolons (groups of three), em dash overuse, rhetorical Q+A, and mirror structures. These are stronger tells than vocabulary.

Pass 3: Add Human Texture — Varies sentence length, adds contractions, lets some thoughts stay unresolved, and makes the author's actual opinion visible.

Also includes special rules for LinkedIn posts and a 14-point quality checklist that runs before returning any rewrite.

Quick Start (Any LLM)

The entire system is two markdown files. You can use them right now:

1. SKILL.md — The main instructions (the 3-pass process, LinkedIn rules, quality checklist)
2. ai-patterns-dictionary.md — The reference dictionary (36+ banned words, 10 structural patterns, tone tells)

Copy the contents of both files into your LLM's system prompt or custom instructions, then paste any text you want humanized.

Setup by Platform

One command, and it works automatically whenever you ask to humanize text:

After that, just say things like "humanize…
