Humanizer

blader

Free

An open agent skill that rewrites AI-sounding text to read like a person wrote it, without changing what the text actually says.

25 Named Patterns: A ranked catalogue of AI-writing tells — from 'not X but Y' staging to decorative bold, chatbot residue, and knowledge-limit disclaimers — each with before and after examples.
Strength-Weighted Detection: The first five patterns justify an edit on a single sighting, while patterns marked weak alone only count when several share a passage, so deliberate stylistic choices survive.
Draft-Critique-Final Loop: Humanizer shows its work by producing a first rewrite, a short critique of whatever still sounds artificial, and then the final version.
No Invention Guarantee: Names, numbers, dates, quotes, and citations must come from the source or the writer; if a sentence needs a missing detail the skill asks rather than fabricating one.
Voice Matching: Supply a writing sample and the rewrite follows its rhythm, word choice, punctuation, and deliberate quirks, including em dashes if you use them.
File-Safe Rewriting: Point it at a file path and it edits prose only, leaving code, data, frontmatter, and link targets untouched.
Agent-Agnostic Install: Distributed as Markdown so it works with any skill-capable agent, via the Skills CLI, the Claude Code plugin, or a ZIP upload in Claude Desktop.
Register-Aware Output: Personal writing keeps the writer's opinions and quirks while technical and reference prose stays neutral and plain.

Cleaning Up AI Drafts: Run a model-generated blog post or essay through Humanizer before publishing so it does not read as machine-written.
Matching a House Voice: Provide a sample of existing published work so rewritten copy matches an established author or brand voice.
Documentation Editing: Point the skill at a repository file to strip decorative headings and staged sentences from technical docs without touching code blocks.
Email and Outreach Polish: Remove sales language and borrowed authority from outbound copy so claims are stated plainly.
Editorial Review: Use the marked list of tells as a critique pass to teach writers which habits read as AI-generated.
Agent Pipeline Step: Chain Humanizer after a drafting agent so generated text is normalized before a human ever reviews it.
