humanizer

Remove signs of AI-generated writing from text to make it sound more natural and human-written. Use this skill when asked to "humanize", "de-AI", "clean up", or "make this sound less robotic". Also triggers when reviewing text for AI patterns, editing content to feel more authentic, or when someone says "this sounds like ChatGPT". Also use when asked to make text "undetectable" or pass AI detection tools. Originally built on top of https://github.com/blader/humanizer, which itself draws from Wikipedia's comprehensive "Signs of AI writing" guide. Substantially evolved with pattern additions for 2025+ and 2026+ model outputs across Claude, GPT, and Gemini, plus LinkedIn-genre AI tells. Optionally calibrates rewrites to the user's voice fingerprint when one exists at ~/.humanizer/voice-fingerprint.md, and applies per-model rule weights when the source model is identified.
