Grammarly vs. ProWritingAid vs. Ginger

With dozens of grammar tool options, it can be overwhelming to select the right one. How do the three top grammar tools compare when it comes to features?

Grammarly’s free plan has generous features and allows you to edit text, but it does not offer a plagiarism checker. ProWritingAid’s paid version allows you to edit longer text and offers a very detailed report about sentence length, similar to Hemingway.

Whilst Grammarly and ProWritingAid stand out, Ginger does impress with text-translation features, as well as an algorithm to detect grammar errors within specific contexts of each sentence.

All three work on Windows and Mac and offer a Chrome plugin.


  • Grammarly is $29.99 billed monthly and $11.66 per month billed annually
  • ProWriting Aid is $70 a year (a little over $5.00 a month.)

  • Ginger is $20.97 billed monthly and $7.49/mo on annual contracts

Guide: Grammar Check Options in Microsoft Word

Many people don’t go beyond the ever-reliable Microsoft Word spellcheck. The issue is Word’s standard spell check isn’t particularly sensitive. It tends to miss nuanced errors, such as misplaced commas, or might recommend changes that aren’t necessary.

However, there are advanced options you can use to get the most out of Microsoft’s native tool.

Here’s how:

  1. Open up Word, then go to File > Options (it is in the bottom left corner on the current version of Word)
  2. Select Proofing
  3. Then, look for Writing Style, right next to that click Settings
  4. That opens up a huge list of Grammar Settings right in Word. The best part is that you can pick and choose which features you want word to check for, including first-person, vague quantities, cliches, weak verbs, and even the Oxford comma. 5. Select the errors you want Word to check for, and click Okay. 

That is all there is to it! If you aren’t looking for a powerful editor with fancy tools like a plagiarism checker, this feature can be a valuable option. And it’s free if you already have Word.


Got questions about grammar checkers? We’ve got you. Here are the answers to your most-asked grammar software queries.

What writing software is best for screenwriters?

Screenwriting often includes dialogue, which can make working with a grammar tool tedious. You can consider ProWritingAid, which serves as a grammar tool, style editor, and writing mentor all in one. It will suggest better word choices and help spot style issues. Then again, the best writing software for you depends on your writing style and preference of correction mechanisms.

Are there specialized software tools for book writers?

Yes. ProWritingAid and Hemingway are combination grammar tools and style editors, both popular with authors. They can spot both misspelled words and weak areas that need a bit more love. ProWritingAid integrates with Scrivener, a popular app with both fiction and nonfiction authors and Google Docs.

What are the best grammar and writing plugins for WordPress users?

Grammarly and Ginger may be ideal choices as they both integrate with WordPress, allowing you to check for grammar mistakes and misspellings in WordPress. Other tools like WhiteSmoke and Slick Write are extensions of your browser so they can be used in conjunction with WordPress.

Which writing software works best for team projects?

Both Grammarly and WhiteSmoke offer business plans, which can make paying for a whole team more affordable. Ideally, the tool you select will work with the other tools you use, such as Google Docs and Gmail, either through a browser plugin or integration.

Which writing software is best for students?

Slick Write is a totally free grammar checker that will catch most mistakes students are prone to make. If you can afford $10.00 per month, we suggest PaperRater, which checks for more issues, such as wordy sentences, and offers a plagiarism checker too.


Now that we’ve covered all the most popular grammar tools, you have a decision to make! Which one will you choose? Start by selecting a few that have the features you need, then take their free trial for a spin. A week or two should be all you need to choose the right writing support tool for your needs.
