How it works

1

Paste your draft

Blog post, newsletter, sales copy, LinkedIn post — paste any professional writing you want feedback on.

2

Get editorial feedback

Structured scores on structure, clarity, tone, argument, and CTA — plus specific rewrites for your weakest spots, in your voice.

3

Improve — and keep improving

RedPen tracks your scores across every post. See your trends, spot your patterns, and know exactly where to focus next.

More than a one-shot fix

Most writers paste into ChatGPT and get generic feedback. RedPen is built around the full coaching loop.

Format-specific feedback

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.

Rewrites in your voice

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.

Score tracking over time

Every analysis is scored and saved. See how your structure, clarity, argument, and CTA trend across posts — and whether you're actually improving.

Pattern identification

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.
