Humanizer
Humanizer is a Markdown-based agent skill that rewrites AI-sounding text so it reads like it was written by a person, without changing the underlying claims or facts.
It works with any agent that supports skills, including Claude Code, Codex and Cursor, and can rewrite pasted text or an entire file while leaving code, data, frontmatter and link targets untouched; given a sample of a user's own writing, it matches that sample's rhythm, word choice and punctuation instead of a generic voice.
It checks a drafted rewrite against a numbered list of twenty-five "tells" of AI-generated prose, such as staging a point instead of stating it directly or dressing up an ordinary fact as a pivotal one, correcting the strongest and most frequent patterns first, and asks for a missing fact rather than inventing one. It shows its work as a first rewrite, a short critique, and a final version.
