Humanize AI Text with Claude Code

What you’ll get

You’ll get AI-generated text that reads more naturally and authentically, free from common “AI-isms” like repetitive phrasing, vague attributions, and overly formal language. This approach works by leveraging a specialized “skill” that analyzes and rewrites text based on a comprehensive guide of AI writing patterns, ensuring a more human-like output.

Tools you need

• Claude Code (paid): A local environment for running Claude AI skills, used here to host the humanizer tool.
• OpenCode (free): An open-source alternative environment for running Claude AI skills, compatible with Claude Code skills.
• Claude (freemium): The underlying AI model that powers the humanization process.

Steps

1. Prepare your environment: Ensure you have either Claude Code or OpenCode installed on your computer. These are local environments that allow you to run AI skills. The author doesn’t provide installation steps for these tools themselves. For OpenCode, you can find setup instructions on its official GitHub page.

   You should see a working Claude Code or OpenCode environment, ready to accept commands.

2. Install the Humanizer skill: Open your terminal and paste the commands for your operating system, pressing Enter after each one.

   On macOS or Linux (bash or zsh):

   mkdir -p ~/.claude/skills
   git clone https://github.com/blader/humanizer.git ~/.claude/skills/humanizer

   On Windows, use PowerShell (the older Command Prompt rejects these commands with “The syntax of the command is incorrect”):

   New-Item -ItemType Directory -Force "$HOME\.claude\skills" | Out-Null
   git clone https://github.com/blader/humanizer.git "$HOME\.claude\skills\humanizer"

   If you use OpenCode instead, clone into its skills directory:

   # macOS or Linux
   mkdir -p ~/.config/opencode/skills
   git clone https://github.com/blader/humanizer.git ~/.config/opencode/skills/humanizer

   # Windows (PowerShell)
   New-Item -ItemType Directory -Force "$HOME\.config\opencode\skills" | Out-Null
   git clone https://github.com/blader/humanizer.git "$HOME\.config\opencode\skills\humanizer"

   The author notes that cloning into the Claude Code skills folder is enough for both tools if you use both.

   You should see messages indicating the repository is cloning and files are being received. A new folder named humanizer will appear inside your ~/.claude/skills (or ~/.config/opencode/skills) directory.

3. Calibrate your writing voice (optional but recommended): To help the skill match your personal writing style, provide a sample of your own writing. In your Claude Code or OpenCode interface, type or paste this prompt, replacing [paste 2-3 paragraphs of your own writing here] with your actual text:

   /humanizer Here's a sample of my writing for voice matching:
   [paste 2-3 paragraphs of your own writing here]

   The model will process your input. While the exact response isn’t specified, you can expect an acknowledgment that your writing style has been noted or that it’s ready for the next step.

4. Humanize your AI-generated text: Now, paste the AI-generated text you want to humanize. In your Claude Code or OpenCode interface, use one of these commands:

   /humanizer [paste your AI-generated text here]

   Or, if you prefer a more natural language approach:

   Please humanize this text: [paste your AI-generated text here]

   The skill will process your text and return a rewritten version. This output should sound more natural, less repetitive, and free from common AI writing patterns.

Original source

This workflow is based on the “humanizer” skill created by blader and shared on GitHub. This skill is designed to remove signs of AI-generated writing from text, making it sound more natural and human.

Notes & variations

• Cost and free-tier alternative: Claude Code requires a paid Claude plan or API credits. OpenCode is a free, open-source environment that runs the same skill, though you still need access to a model to power it.
• Common mistake: Not providing a sufficient or representative sample of your own writing for voice calibration. This can lead to the humanized output still sounding somewhat generic rather than truly matching your personal style.
• Tip for better results: Review the “33 Patterns Detected” section in the original source’s README.md file. Understanding the specific AI writing patterns the skill targets can help you refine your initial AI-generated text or better evaluate the humanized output.
