Before reviewing both, let us see the features and primary goals for both tools. The primary purpose of Microsoft Word is writing and printing the documents. Grammarly, on the other hand, is a unique tool specially designed for checking grammar mistakes.

Microsoft Word comes with basic grammar and spells checking features. It marks mistakes in red, blue, or gold underline to help you understand the mistake type. Grammarly free comes with a tool which also checks for the basic mistakes. It highlights the text in red colour.

Grammarly is a great tool, and because it is specially made for checking grammar and spelling mistakes, it could find and fix more issues than Word. Here is the list of fixes which Grammarly could solve.

  • Changed on YouTube to On YouTube, and also it added a comma after YouTube in the second line.
  • It added a comma after “messages”.
  • Grammarly added, “the” before email and “a” before particular video at the end of the paragraph.

Here is the list of fixes which Word could solve but not Grammarly.

  • It changed Youtube to YouTube.
  • It deleted “particular” before “video” because it was unnecessary.

Here are a couple of issues both could not fix.

  • In the first line, Youtuber should be YouTuber.
  • google should be Google.

Issues with both tools

Anyway, none of the software is perfect, but if you have both, then it is essential to check the text in both. I have been using both for a long time, and here are some cons about both.

  • Grammarly lacks on checking the brand names.
  • Microsoft Word isn’t good at suggesting comma.
  • Relying on Grammarly can be harmful. For example, sometimes it keeps suggesting the verbs like the word “software” to “tool” then same “tool” to “machinery”. You can see we were talking about computer software, and in two clicks Grammarly changed it to a physical machine.

  1. Thank you for this useful comparison, especially in pointing out some the specific differences between the two. Ultimately, it comes down to price. I was surprised to see the relatively high price tag of Grammarly premium compared to Microsoft Office. Considering everything that comes along with Microsoft Word, including a top-tier office productivity suite, collaborative functionality, access to a cloud drive, etc., Grammarly premium is simply too expensive and definitely not an option worth considering for casual writers like me, which I imagine comprise the vast majority of people.

    1. You are right, NM. Grammarly premium is expensive compared to Word. It is not for casual writers. Grammarly premium is for serious writers like bloggers.
