This is proper copy editing, not rewriting. It runs your marketing copy through seven focused sweeps: clarity, voice consistency, benefit bridges ("so what?"), proof backing up claims, vague-to-specific upgrades, emotional resonance, and friction removal. Each pass catches different issues you'd miss trying to fix everything at once. It checks for product context files first to maintain your brand voice. Use it when you have copy that works but needs polishing, or when stakeholders say "this feels off" but can't pinpoint why. Beats the usual unfocused "make this better" approach that often makes things worse.
