Once installed, just ask Claude to humanize text naturally:

humanize this text: Your AI-generated content here...

Or use the slash command:

/humanize Your AI-generated content here...

You can also point it at a file:

/humanize path/to/article.md

• Rewrites ChatGPT, Claude, Gemini, Copilot, or any AI-generated text to sound human
• Passes GPTZero, ZeroGPT, Turnitin, Copyleaks, and other AI content detectors
• Preserves meaning, facts, and formatting (headings, lists, markdown)
• Supports 1-3 humanization passes for deeper rewriting

The skill calls the free DiaIQ Humanizer API. No authentication required. Your text is sent to the API, humanized using a fine-tuned local AI model, and returned directly in your terminal.

DiaIQ converts video recordings into blog posts, newsletters, social media posts, and more. The humanizer was originally built for our own content pipeline and is now available as a free public tool.
