humanizer
humanizer is an agent framework - Agent skill that removes signs of AI-generated writing from text.
Overview
Humanizer makes AI-written text sound like a person wrote it, without changing what it says. It is built on Wikipedia's Signs of AI writing, the guide Wikipedia editors use to catch AI-generated text, and it works in Claude Code, Codex, and any other agent that supports skills.
In a blind test, judges preferred Humanizer's rewrite over the original AI text 16 times out of 16 (#229).
Humanizer edits for human readers. Getting past AI detectors is not a goal, and detectors still flag most of its output.
- Not X but Y: "It's not just a feature, it's a shift." 2. One-line closers: "Let that sink in." 3. Sayings that sound deep: "At its core, what really matters is..." 4. A staged run-up: "Here's the thing." "Honestly?" 5. Arguing with no one: "I'm not saying X, but..."
The plugin answers to '/humanizer:humanizer'. It needs Claude Code 2.1.142 or newer; on older versions, use 'npx skills add blader/humanizer --global --agent claude-code'.
