RedPen reads your draft like an experienced editor — structure, clarity, tone, argument — and tracks your scores over time so you know exactly what to work on next.
Try 2 Free AnalysesNo credit card required
Blog post, newsletter, sales copy, LinkedIn post — paste any professional writing you want feedback on.
Structured scores on structure, clarity, tone, argument, and CTA — plus specific rewrites for your weakest spots, in your voice.
RedPen tracks your scores across every post. See your trends, spot your patterns, and know exactly where to focus next.
Most writers paste into ChatGPT and get generic feedback. RedPen is built around the full coaching loop.
LinkedIn posts, newsletters, blogs, and sales copy have different conventions. RedPen knows them — it doesn't give you the same feedback regardless of what you wrote.
RedPen rewrites your weakest sentences the way you write, not the way an AI writes. Paste examples of your work and it calibrates to your style.
Every analysis is scored and saved. See how your structure, clarity, argument, and CTA trend across posts — and whether you're actually improving.
RedPen surfaces what you consistently get wrong. If your opening averages 5.1 across ten posts, that's where to focus — not whatever happened to score low today.
