Humanizer, 56k stars: strips AI-writing tells using Wikipedia's checklist
sujingshen · x · 2026-10-13
blader/humanizer (56k stars, MIT) is an Agent Skill that removes signs of AI-generated writing based on Wikipedia editors' "Signs of AI writing" guide, while preserving meaning.
Key points:
- Scans 26 AI-writing patterns — "Not X but Y" constructions, tidy moral-of-the-story endings, fake-profound filler, padded intros, arguing with strawmen; weak signals must stack before it rewrites
- Works with Claude Code, Codex, and other agents via npx skills
- Handles pasted text or edits prose in files while leaving code and frontmatter untouched
- Accepts your own writing samples to match your voice
- Blind test: judges preferred Humanizer output 16/16
The thread's takeaway: AI-ness lives in over-structured sentences, not factual errors — cut half the connectives and it reads human. The goal is human readers, not beating detectors.
