Testing ProWritingAid or Grammarly – Which Performs Better?

I am going to test Grammarly and ProWritingAid proofreading capabilities to see differences between detecting issues and improvement suggestions.



I took some random article and pasted its content into both tools. I don’t want to go into long details of test as each tool has its own set of proofreading tools, so in short, both tools found approximately the same number of issues with content. The difference was slight in regards to some suggestions, readability, variety, etc.



For second test, I decided to use part of this article. In this example, I noticed that each tool had mostly different suggestions on which parts of the article should be fixed or improved.

It is hard to conclude which performs better on proofreading field. I would say both do a good job, and because they work slight differently, they will not have same suggestions for fixing and content improving.


Grammarly vs ProWritingAid Verdict

Use Grammarly’s free version if you’re low on cash. In comparison to Word or Google Docs, it is more accurate.

Grammarly Premium is an excellent choice if you frequently write non-fiction materials such as articles and emails. It will be able to discover more mistakes. Grammarly Business is the best option if you cooperate with other authors or work in a team.

Grammarly is one of the most sophisticated and up-to-date proofreading tools on the market today. Right now, it can identify mistakes based on over 400 different parameters. It’s also accessible on a variety of platforms, including MS Office. You can also use the web browser addons and the desktop app.

ProWritingAid is also an excellent tool for improving writing. It has more features than Grammarly and focuses more on the style and readability of the text. Even though it can resolve many grammatical and spelling errors, Grammarly is a better option for that purpose if you are looking for simpler tool.

Grammarly and ProWritingAid have the following key differences:

  • Grammarly is better suited for short blog articles, but ProWritingAid is best suited for longer writing pieces such as academic papers.

  • Grammarly focuses on correcting more basic mistakes, while ProWritingAid provides in-depth explanations for the suggestions it makes.
