2

Get editorial feedback

3

Improve with rewrites

Get your 3 weakest sentences rewritten with explanations of what changed and why. Not vague suggestions — actual rewrites.

The gap between Grammarly and a human editor

Grammar checkers

Fix commas and typos. Useful, but they can't tell you that your opening buries the lead or that paragraph 3 contradicts your thesis.

RedPen

Reads your piece like an editor. Evaluates structure, argument, tone, and persuasion. Gives you specific rewrites for your weakest spots. $25/month.

Human editor

The gold standard, but $50-200 per piece and days of turnaround. Not practical for every blog post and newsletter.
