Wikipedia’s AI Red Flags Turn into a Guide: The Claude Humanizer Plugin
Siqi Chen has released 'Humanizer,' an open-source plugin for Anthropic's Claude Code that uses Wikipedia's AI detection patterns to make AI writing sound more human and avoid detection.
Is your AI writing too robotic? Tech entrepreneur Siqi Chen just released an open-source solution that uses Wikipedia's own 'cheat sheet' to hide chatbot fingerprints. The tool, called Humanizer, is a plugin for Anthropic's Claude Code assistant that instructs the AI to stop following the predictable patterns usually associated with Large Language Models.
Anthropic Claude Humanizer: Leveraging Wikipedia’s Red Flags
The plugin functions by feeding Claude a specific list of 24 language and formatting patterns. These aren't just random guesses; they are the exact markers that Wikipedia editors use to flag AI-generated content. According to Chen, it's incredibly effective to tell an LLM exactly what behaviors to avoid to sound more authentic. The plugin has already gained over 1,600 stars on GitHub as of Monday.
The Origins: WikiProject AI Cleanup
The source material for this 'humanizing' prompt comes from WikiProject AI Cleanup, a volunteer group founded by French editor Ilyas Lebleu in late 2023. These editors have tagged more than 500 articles for review. In August 2025, they formalized their findings into a list of AI 'giveaways.' What was intended as a shield for encyclopedia integrity has now become a sword for those looking to bypass detection.
