Humanizer (Remove AI Writing Tells)

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-humanizerskill.
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
- "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.
- Landing page review: run
python3 scripts/copy_scan.py landing.mdfor the mechanical hits, then rewrite using the copy-specific tells. - 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.
- Open a terminal (Terminal on macOS/Linux, Git Bash on Windows).
- Clone the repo:
git clone https://github.com/NulightJens/humanizer-stack.git - Create the skills folder if needed:
mkdir -p ~/.claude/skills - Copy the skill in:
cp -r humanizer-stack/skills/humanizer ~/.claude/skills/ - Optional but recommended: copy the bundled
structural-humanizerskill the same way to run the second pass. - Restart Claude Code and confirm
humanizerappears in your skill list. - Try it: "Humanize this draft and list what you changed." The optional copy_scan.py step requires python3 on your machine.
