Expert copy editor for marketing and conversion content that improves what's already written rather than starting from scratch. Reach for this when you need to tighten, refresh, or de-slop existing copy—whether it's a landing page, email, or outdated content. It removes AI tells like 'it's not X, it's Y' reveals and 'no X, no Y, no Z' lists while preserving your core message and brand voice.
- Multiple focused editing passes (clarity, tone, structure) instead of one unfocused review
- Removes AI tells: false dichotomies, redundant negation lists, and rambling comma clauses
- Reads product-marketing.md context to align edits with your brand voice and customer language
- Preserves the author's intent and message while sharpening how it lands
