Microsoft Editor vs. Grammarly

Microsoft Editor vs. Grammarly

Grammarly is a popular writing assistant available on multiple platforms. Microsoft Editor is a Grammarly alternative from Microsoft.

Which one is more useful? This is the Microsoft Editor vs. Grammarly battle to help you decide.

Quick overview

Both are freemium writing assistants available for browsers. Grammarly is more accurate and has a Windows and mobile app to check grammar. It also supports more websites than Microsoft Editor.

Grammarly can be installed on Microsoft Word, whereas Microsoft Editor is a built-in checker.

Which is best for grammar

From the tests I conducted below, Grammarly is more accurate and advanced in finding errors.

Platforms both support

Microsoft Editor works on major browsers (Chromium-based). It’s only web-based, so there is no desktop or mobile app.

Grammarly supports desktop computers, office suites, Google Docs, and mobile phones. The app has different features on each platform.

On the web and Windows, it checks mistakes in any text editor; on mobile, it’s a keyboard app checking writing as you type.

Which wins: LanguageTool vs. Grammarly

Languages both support

Microsoft Editor wins this round with support for over 50 languages. However, the efficiency of checking mistakes in all languages is not the same.

Grammarly supports the 4 English language variations:

  • English American
  • English British
  • English Canadian
  • English Australian


After testing both on many websites, I concluded that Grammarly supports more websites.

Microsoft Editor worked on popular sites, including Gmail, Outlook, Word, Docs, etc., but it did not work on many smaller websites.

Other Grammarly features

Grammarly has a few other features we don’t see in Microsoft Editor.

While suggesting a fix, it shows the error type with more information. There is a button that goes to an article discussing that issue type.

It sends you the weekly statistics, including your productivity, mastery, and vocabulary score. It also shows the type of mistakes you make frequently.

You can double-click on a word in browsers to see its meaning and synonyms. Lastly, you can save personal words in the dictionary to stop the app from correcting you.

Premium and pricing

Microsoft Editor vs Grammarly

Pricing is the Editor vs. Grammarly article’s last and most crucial section. Microsoft Editor is a part of the Microsoft Office subscription.

The free plan checks for basic grammar and spelling issues, while the premium app supports the following:

  • Advanced grammar checking
  • Clarity
  • Conciseness
  • Formal language
  • Vocabulary
  • Punctuations conventions

Microsoft Office 365 Personal costs $6.99 per user per month. The plan offers Office apps, such as Word and Excel.

The upper-hand plan is Microsoft 365 Family costing $9.99 per month. The features are the same, but you can add up to six people to use the Office apps and Microsoft Editor.

Moving to Grammarly, you have a couple of options. Grammarly offers one premium plan for individuals and one for businesses.

One can pay month to month, quarterly, or yearly. The one-month plan costs $30, the quarterly plan costs $60 ($20/mo), and the annual plan costs $144 ($12.20/mo). You can expect features such as:

  • Clarity
  • Tone adjustments
  • Plagiarism checker (check out my tests on its accuracy)
  • Word choice
  • Formality level
  • Fluency
  • Additional advanced suggestions

The business plan is for three or more users. In this plan, you track your team’s performance by evaluating brand tones, style guides, and snippets.

Conclusion and recommendation

When Microsoft Editor came, it was useless. It did not work correctly, and still, it sometimes shows the same nature.

Moreover, the tests showed that Grammarly Free performs better than Microsoft Editor.

So, at this point, I don’t see any reason to use Microsoft Editor. We may see improvements from Mircosoft’s end, but let’s focus on Grammarly for now.

From people who type over 500 words daily to those who occasionally type, having one of those tools can benefit them in many ways.
