Spell and grammar check – Test 01

Let us dive into the comparison of Grammarly vs Microsoft Word and see which one can perform better under certain circumstances. I took a piece of content and tested it in both the software. Both software showed corrected the grammar, but after fixing all the issues, the text was a little bit different. Below is the original text which I tested on both tools.

Original text

Being a Youtuber I get lots of messages every day, and I don’t have enough time to respond to each person because I’m busy learning how google works. on Youtube so that’s why I have hired an assistant who handles all these messages and if he finds anything important he sends the message in email with particular video URL.

If you want I can ask the guy if he can work for you too in his free time but he is expensive and it can cost you a lot if you ask him to work on Sundays.

Grammarly premium 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. Here is the detailed comparison of both tools.

  2. It added a comma after “messages”.

A review video

Before we begin comparing both services, let’s watch a video made purely for the comparison. The video shows the same mistakes mentioned in this article and explains what happens and why.

Issues with both tools

Anyway, no software is perfect, but if you have both, then it is essential to check the grammar in both the tools. I have been using both for a while now, and here are some of the negatives about both.

  1. Grammarly has a lack of knowledge about checking for brand names.
  2. Microsoft Word isn’t good at suggesting comma.
  3. Overuse of 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.
