Humanize is an agentic skill that rewrites AI-generated copy to remove the most common AI writing tells, overused words, hollow phrasing, em dashes, inflated language, without changing the meaning, length, or intent of the original text. It fixes the style, not the substance.

What it removes:

At it’s core the skill starts with known AI tells as documented in Wikipedia – en.wikipedia.org/wiki/Wikipedia:Signs_of_AI_writing, then adds additional AI writing tells on top of that base.

• Overused AI vocabulary (“pivotal,” “underscore,” “tapestry,” “delve,” “vibrant,” and 50+ other words and commonly used phrases)
• Em dashes, replaced entirely with commas, colons, or sentence breaks
  (*Important: depending on the model, it can be very difficult to force it to stop using em-dashes. Always review your final output)
• Puffery and fake significance (“a pivotal moment in the evolving landscape of…”)
• “Not just X, but Y” constructions, collapsed into plain statements
• Excessive bold formatting
• Chatbot sign-offs like “I hope this helps” and “Let me know if you need anything”
• You can add new tells to the skill by simply editing the skills.md file from your platform’s dashboard (if available), or using a text editor on your computer, then re-uploading the skill.

After each pass, the skill tells you exactly what was changed and asks whether you want further edits or to download the result as a Word doc, plain text, or Markdown file.

Installation (easiest way)

The easiest way to install skills on most platforms is to either download the skill, or copy the GitHub URL and tell your platform “Install this skill” and give it the link or the file. Today most platforms will install the file from your prompt.

Claude Cowork Installation

1. To install: Unzip humanize.zip,
2. Then go to Cowork → Settings → Capabilities → Skills → Upload Skill, and select the unzipped humanize folder.
3. That’s it.

How to use it:

• Install Humanize to supplement your already existing AI content process. Even if you have your projects, and work spaces all set up with your brand’s voice, AI can still use it’s familiar tells in your writing. Humanize is an extra fail safe against that.
• There are no slash commands. Once the skill is installed it activates automatically on most platforms or there’s a toggle to turn it on.
• Once its installed you can use natural language to run it against your pasted or, uploaded or other AI created copy such as:

• “Humanize this”
• “Make this sound human”
• “Remove the AI tells”
• “This sounds like ChatGPT, fix it”
• “Clean up the AI writing”

No special syntax required.
