Grammarly and Microsoft Word are different programs with one feature that goes against each other: writing assistant.
Word is designed for writing and printing documents, whereas Grammarly is a writing assistant.
How do both perform in the tests I’m going to conduct? This is the Grammarly vs. Word comparison.
Note: Microsoft Word now uses Microsoft Editor as a writing assistant. You can check out its comparison with Grammarly if you are interested.
Grammarly
Grammarly is a grammar checker tool for desktop, mobile, major browsers, and Microsoft Word.
It checks over 400 types of mistakes in writing and can be used to check grammar mistakes in different versions of English.
The official website says over 34 million users use Grammarly to improve their writing.
Grammarly is free software that checks for basic mistakes. It is also available in paid subscriptions to fix more complex grammar errors.
Microsoft Word

Grammar checking is a built-in feature in Microsoft Word which works offline. Regarding pricing, the mobile and online versions are free, but the desktop version is offered in subscriptions.
Test 01
Let us dive into the first test and see which one performs better. In this test, we will check a paragraph in both.
Results
Grammarly is a great tool, and because it is specially made for checking grammar and spelling mistakes, it can find and fix more issues than Word. Here is the list of fixes that Grammarly could solve.

- Grammarly added “the” before email and “a” before a particular video at the end of the paragraph.

Round winner: Grammarly
Issues with both tools
None of the apps is perfect, but if you have both, it is essential to check the text in both. I have been using both for a long time, and here are some issues.
- Grammarly lacks in checking the brand names.
- Microsoft Word isn’t good at suggesting commas.
- Relying on Grammarly can be harmful. For example, sometimes it keeps suggesting the word “software” to “tool” and then the same “tool” to “machinery.” We were talking about computer software, and in two clicks, Grammarly changed it to a physical machine.

grammarly sucks...

According to the majority of people, hard work is the key to success. Inserted a comma after people. "According to the majority of people," Is a statement. "Hard work" is the answer to that statement. I picked all of those errors as I proof read and text edit my own work. My main frustrations are, when proofreading others work, is the starting a sentence with a conjunction and ending a sentence with a preposition! "And that's another thing that we are glad of!" Continual (not continuous) use of "It was.." Superfluous words. "How long are you here FOR?" "Now, to continue.." English is such a beautiful rich language and I enjoy twisting the words for emphasis. It is fun. Kind regards, Dennis.

Word capitalizes the start of sentences in 2020 anyways so it may have improved.

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.

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.
