Refine AI-generated text to sound like natural human writing
Use this tool as a final step before publishing blog posts or document drafts. It removes the unnatural rhythm and exaggerated expressions found in AI-generated sentences, making the text appear as if written by a person. Based on criteria used by Wikipedia editors to identify AI-generated content, it detects and fixes 26 patterns while preserving the original meaning.
How it detects AI writing traces
The tool operates based on Wikipedia's 'Signs of AI Writing' guide. Language models predict the most likely next word, which leads them to generate neutral and regular sentences for a broad audience. This tool identifies sentences written in that 'default' style and rewrites them as if a person wrote them for a specific audience and topic. For example, it changes contrastive phrases like 'not a simple feature, but a turning point' or one-sided closing sentences like 'savor that meaning' into direct descriptions. It checks all 26 patterns and fixes them in order, starting with the strongest signals.
Five key correction targets
The most common and strong signals of AI writing are as follows.
- Negative-to-positive structure It removes sentences structured as 'not X, but Y' and states the core content directly.
- Dramatic endings It deletes or merges short exclamations or moralizing one-liners that repeat in each section into specific claims.
- Seemingly deep aphorisms It replaces abstract expressions like 'in the end, what matters is...' with concrete facts or claims.
- Pre-main-point narrative It removes introductory phrases like 'honestly?' that lead into the main point and starts the content immediately.
- Hypothetical counterarguments It removes sentences that assume and refute opposition that the other party has not actually expressed.
Installation and usage
It can be used in various agents such as Claude Code, Codex, Gemini CLI, and GitHub Copilot. If you use Claude Code, add the plugin with the /plugin marketplace add blader/humanizer command and invoke it with /humanizer:humanizer. For other agents, run the npx skills add blader/humanizer --global --agent [agent name] command. If you provide a file path, it modifies only the body of that file and leaves code or data untouched. If you want to reflect your own writing style, provide 2-3 paragraphs of your writing as a sample, and it will match the rhythm and vocabulary.
Things to check before use
This tool does not aim to fool AI detectors. Detectors can still classify most of this tool's output as AI. Therefore, it is suitable when the goal is to improve text readability and naturalness, not to evade AI detection. For documents where factual accuracy is important, remember that the tool does not invent missing information but asks questions. It is released under the MIT license for free use and requires Claude Code version 2.1.142 or higher.
