Humanizer (Remove AI Writing Tells)

An editing skill that finds and rewrites 24 tell-tale AI writing patterns, based on Wikipedia's "Signs of AI writing" guide.

Content & WritingBeginner★ 297⑂ 23AI score 10/10Last updated: Jul 24, 2026

What it does

  • Scans text for 24 documented AI tells: inflated significance ("stands as a testament", "pivotal moment"), promotional language, superficial "-ing" analyses, vague attributions ("experts believe"), em dash overuse, rule-of-three padding, negative parallelisms ("it's not X, it's Y"), mechanical boldface and emoji, chatbot residue ("I hope this helps!"), hedging and filler phrases.
  • Every pattern ships with a before/after rewrite, so the instruction is to rewrite naturally rather than just delete keywords.
  • Includes a "personality and soul" section: vary sentence rhythm, take a position, use first person when it fits — while explicitly banning embodied-emotion performance ("my chest tightened"), which it flags as the strongest AI structural tell.
  • For marketing copy, landing pages, product UI or social posts, it adds a copy-specific reference (references/copy-tells.md) and a deterministic scanner (python3 scripts/copy_scan.py <file>).
  • States its own scope honestly: this is pass 1 of 2, covering surface wording and punctuation only; structural tells require the companion structural-humanizer skill.

Who it's for

  • Bloggers, newsletter writers and ghostwriters cleaning up AI-assisted drafts
  • Marketers and brand editors who need copy that doesn't read as machine-generated
  • Developers and technical writers de-hyping READMEs, release notes and docs
  • Students and analysts who want plainer, more specific prose

Examples

  1. "Humanize draft.md" → the skill removes em dashes, AI vocabulary like "landscape" and "pivotal", and rule-of-three lists, then returns the rewrite plus a change log.
  2. Landing page review: run python3 scripts/copy_scan.py landing.md for the mechanical hits, then rewrite using the copy-specific tells.
  3. Replace "industry experts believe..." with a named source and a number, and swap a generic "the future looks bright" ending for a concrete next-step sentence.

Install the skill I found on Claude Skill Mart.
Copy the skills/humanizer folder from the GitHub repo NulightJens/humanizer-stack into my ~/.claude/skills/humanizer/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/NulightJens/humanizer-stack.git && mkdir -p ~/.claude/skills && cp -r humanizer-stack/skills/humanizer ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal (Terminal on macOS/Linux, Git Bash on Windows).
  2. Clone the repo: git clone https://github.com/NulightJens/humanizer-stack.git
  3. Create the skills folder if needed: mkdir -p ~/.claude/skills
  4. Copy the skill in: cp -r humanizer-stack/skills/humanizer ~/.claude/skills/
  5. Optional but recommended: copy the bundled structural-humanizer skill the same way to run the second pass.
  6. Restart Claude Code and confirm humanizer appears in your skill list.
  7. Try it: "Humanize this draft and list what you changed." The optional copy_scan.py step requires python3 on your machine.
