Humanize
Review and edit copy to remove signs of AI-generated writing. Based on Wikipedia's "Signs of AI writing" guide maintained by WikiProject AI Cleanup. Contains 30 rules across 6 categories.
When to Apply
- Editing AI-generated drafts
- Reviewing text that sounds robotic or corporate
- Cleaning up writing before publishing
- Making technical content sound more natural
Constraints (Non-Negotiable)
- Preserve meaning, factual claims, and intent.
- Preserve coverage: don't drop list items, options, or qualifiers (e.g., removing one option from a list) unless they're truly redundant.
- Do not add new facts, dates, quotes, or citations that are not already present or user-provided.
- Do not imply a source ("according to…") unless you can name it from the input.
- Keep genre and audience intact (e.g., neutral encyclopedic tone vs. personal essay). Use
voice-soulonly when that voice fits. - Don't rewrite quoted material unless the user asked to rewrite the quote itself.
- Avoid em dashes (—). Replace with commas, periods, or parentheses.
- Don't introduce new AI patterns. Your rewrite must pass the same rules you're applying. Common traps: "Here's the thing:", "It's not about X, it's about Y", formulaic hooks that try to sound casual.
