Claude Skill A Claude Skill that rewrites AI-flat copy in your defined brand voice, enforces em-dash and banned-phrase removal, and flags common LLM tells.

Every team that uses LLMs to draft also needs to detect and clean the tells. The Humanizer reads a draft, applies your team’s voice rules, strips em-dashes and banned phrases, and flags hedging, the rule-of-three pattern, listicle drift, and the other common LLM signatures. Output is a clean draft plus a one-line summary of what it changed.

What it does

• Step 1, draft: The draft, plus a reference to your team’s voice and style guide.
• Step 2, detect: Em-dashes, banned phrases, hedging, the rule-of-three pattern, listicle drift, AI-flat structure.
• Step 3, rewrite: Each flagged passage gets a humanizer pass that preserves meaning and tightens voice.
• Step 4, report: Updated draft plus one-line summary: counts of em-dash removals, banned phrases swapped, hedging tightened.
