What is ProWritingAid?

ProWritingAid is an AI grammar checker where you can improve your grammar, perfect your writing style, and check for plagiarism.

Our Verdict — Best Grammar Checker

Price: Starts at $30/month

The Best Part:

  • It’s your writing coach. ProWritingAid doesn't just catch your grammar errors, it also monitors and showcases analytics of how much you've grown as a writer over time. 

The Worst Part:

  • Extra fees for plagiarism checks. ProWritingAid’s plagiarism checker comes at an additional cost on top of your subscription, starting at $10 for 10 checks.

Get it if you want a real-time AI grammar checker to polish and improve your writing.

I recommend you get started with the Free plan, then upgrade to the Yearly Premium plan for $120/year.
