If you’re confused about which tool you should use, read this comparison guide till the end. We will be comparing these two tools in terms of accuracy, user-friendliness, spelling, editing features, and customer service response.

For this review, we will demo both products using an article about lawn care from one of our portfolio websites.

1. Interface & Design

You won’t be able to take maximum advantage of any tool if its interface is not user-friendly. So don’t forget to check with design and interface before investing in any proofreading tool. Let’s find out how good Grammarly and ProWritingAid are in terms of ease of use.


Web Editor

Grammarly features a clean web editor. You can upload your document by clicking on the “upload” button or simply copy and paste your text in the editor. The good thing is, you can add this tool to Chrome as an extension, making it exceptionally easy to use.

Apart from this, identifying errors is not that difficult with Grammarly. You will see your mistakes broken into categories. You simply need to click on your errors to see the suggestion.

Google Chrome Extension

Grammarly has a Google Chrome plugin that plugins into most forms on the internet automatically so that you can check your grammar as you go. The Chrome plugin also auto-corrects your writing as you type, so you edit less later.

Microsoft Word Editor

The Word editor works just like Grammarly’s web editor, except that the suggestions are embedded directly in Word so you don’t have to leave your favorite writing software.

You can even use Microsoft’s Editor side-by-side with Grammarly’s editor.

Web Editor

Compared to Grammarly, the ProWritingAid interface is not that clean. It shows your errors on the left side of the app. To see the suggestions, you need to click on a tiny arrow and then hover over the text to check the recommendations.

The web editor has a sidebar that shows how you can improve your writing based on various attributes, including grammar/spelling, sentence length, etc. The interface can take some getting used to since what qualifies as green/good is not always intuitive. For example, the green dots showing whether your writing meets that attribute do not line up in the center of the sidebar, so visually it can be confusing to understand when your writing meets the bar for that attribute.

Unlike Grammarly, suggested improvements are hidden behind a tab in the sidebar labeled “Improvements” which makes it hard to see how you can quickly edit the text.

Google Chrome Extension

Like Grammarly, ProWritingAid has a Chrome plugin that will show up in just about any text form on the web, including while we were editing this article.

The biggest disadvantage of ProWritingAid’s Google Chrome plugin that we found was the lack of auto-correction as you type. This is one thing that Grammarly has nailed. While it may seem trivial, Grammarly has built such robust AI that their auto-correction is almost always 100% correct.

Microsoft Word

ProWritingAid’s Office integration is very similar to Grammarly’s. ProWritingAid showed all of the same suggestions as their web editor and focused on the “improvements” sidebar so that it was the first thing we saw.

Winner: Grammarly

Grammarly is the clear winner in terms of user interface since the sidebar often clutters ProWritingAid’s interface and hides the important information about suggested improvements.

2. Features

Both Grammarly and ProWritingAid support a variety of features to help you write better content.


Grammarly comes with both a desktop app and a web version and can be integrated into Microsoft Word. The browser extension is also very helpful to automatically correct grammar and spelling mistakes in email and other web forms. Both the desktop and web versions support multiple platforms. Moreover, you can use it on your Android and iOS phones with the mobile app. It supports both the free and paid versions.

Some of the major features of Grammarly include:

  • Grammar checker
  • Plagiarism checker
  • Spelling
  • Punctuations
  • Tone detector
  • Tone rewriter
  • Passive voice detection
  • Word variety
  • Style suggestions
  • Repetitive words
  • Weak adjectives
  • Word variety

ProWritingAid supports more features than Grammarly. However, it does not support the iOS and Android app. Similar to Grammarly, it comes with both free and paid versions. Some of the additional features of ProWritingAid which are missing in Grammarly include:

  • Dialogue checks
  • Context-sensitive style suggestions
  • Homonyms
  • Visualize Sentence
  • Word Explorer
  • Contextual Thesaurus Report

Winner: ProWritingAid

ProWritingAid offers more features than the free version of Grammarly, but similar levels of features as Grammarly Premium.

3. Accuracy

Accuracy is an important feature to look into when choosing a proofreading tool. After all, everyone wants their content to be correct.


We’ve been using Grammarly for years on our own websites and have found that it catches most errors. As you can see from the side-by-side comparison of the two products, Grammarly flagged more issues, including the British version of the word “fiber”.

When we evaluate the entire article, Grammarly produced fewer errors than ProWritingAid, but we accepted more of its recommendations. Thus, we can say, though Grammarly determines fewer errors, but is more accurate in its recommendations. 


Compared to Grammarly, ProWritingAid provided more suggestions throughout the entire test article, but we accepted more of the Grammarly corrections. 

When writing this article, we noticed ProWritingAid flagged the misspelling of “plugin” as you can see below, but none of the suggestions were accurate.

According to our testing, ProWritingAid seems like a better tool for fiction writers as it takes care of things like fragmented sentences and dialogue better than Grammarly.

ProWritingAid impressed us with its ability to remove fluff from our articles. We noticed how many filler words we used. For example, in this review, we included the following sentence at the beginning:

“For the purposes of this review,”

which ProWritingAid corrected to:

For this review,”

ProWritingAid did this on several occasions, and removing the fluff was always the best option.

Winner: Tie

Grammarly and ProWritingAid both have their strengths and weaknesses in terms of accuracy. While we accepted more of Grammarly’s suggestions, ProWritingAid offered a lot of helpful tips to improve the flow and readability of our writing.
