How do both work?

Writing Assistant Tools
Writing Assistant Tools

Microsoft Editor comes as an extension for major browsers. It can be enabled on Microsoft Word to fix mistakes while typing.

Grammarly, in comparison, is a straightforward tool that works as you type. It is a multi-platform program, and depending on the platform; it offers different features.


Microsoft Editor, as mentioned, is for browsers. It works on many websites, but you don’t get any desktop or mobile apps.

On the other hand, Grammarly supports desktop computers, office suites, and mobile phones. Here is where Grammarly can be used:

  • The extension supports most major browsers, including Chromium browsers and Mozilla Firefox. The extension checks for grammar issues as you type in the text box.
  • It comes as an add-in for Microsoft Word.
  • It is currently in beta for Google Docs.
  • The app can be installed on Android and iOS as a keyboard that also checks your writing as you type (screenshot).
  • The web editor supports rich text editing and all other functionalities that Grammarly offers.
  • The desktop app, which almost looks like the web editor, is available for Windows PC.

Microsoft Editor

  • Supports over 60 languages: Apparently, Microsoft Editor does not offer any features other than multi-language support. Also, according to its settings page, the efficiency of checking mistakes in all languages is not the same.


  • Separating different types of mistakes: Grammarly, while suggesting a fix, shows the error type with more information. There is a button that goes to an article discussing that issue type.
  • Weekly statistics: You get weekly statistics, including your productivity, mastery, and vocabulary score. It also shows the type of mistakes you make frequently.
  • Meanings and synonyms: One can double-click on a word to find out its meaning and synonyms.
  • Personal dictionary: Words that are not in the English language can be added to the personal dictionary.

To find the best tool, we must see both in action. In this section of Microsoft Editor vs. Grammarly, I’m conducting two tests and finding the most accurate tool. Both tests are recorded below for you to see for yourself.

Test 1

Microsoft Editor vs Grammarly Test 1

Microsoft Editor found six issues in the first test, while Grammarly found six grammatical issues, one language variant error, and one conciseness mistake. The winner of this round is Grammarly.

Test 2

Like the first test, we see Grammarly winning in the second test. Microsoft Editor’s AI found six mistakes. Grammarly, on the other hand, suggested fixes for nine issues.

Both tests prove that Grammarly is better at checking and fixing grammar and spelling mistakes.

Premium and pricing

Pricing is the last and an important section of the Editor vs. Grammarly article. 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:

  1. Advanced grammar checking
  2. Clarity
  3. Conciseness
  4. Formal language
  5. Vocabulary
  6. 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 you get 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 in total ($20/mo), while the annual plan costs $144 ($12.20/mo). You can expect features such as:

  • Clarity
  • Tone adjustments
  • Plagiarism checking (see it in action)
  • Word choice
  • Formality level
  • Fluency
  • Additional advanced suggestions

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

What’s best for you?

One thing I don’t like about Microsoft is not testing the program properly. When Microsoft Editor came, it was useless. It did not work correctly, and still, it sometimes shows the exact nature.

Moreover, from the tests, we found 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 until we don’t.

Microsoft Editor vs. Grammarly: Websites


From people who type over 500 words a day to people who occasionally type, having one of those tools can benefit in many ways. Even though there are a couple of downsides to using writing assistants, the benefits outweigh those disadvantages.

Anyway, I must stop writing the Microsoft Editor vs. Grammarly article now because I have covered everything you need to know to decide on the right program. Feel free to leave your remarks in the comments to help improve this article.
