Grammarly vs. ProWritingAid: Best Grammar Checking App

Grammarly and ProWritingAid are two of the most popular spelling and grammar checking apps out there.

So, which one is better?

At first glance, they can seem very similar; however, their small differences can make a large impact depending on each user’s needs.

Let’s get into the nitty-gritty and dissect the details of each app to settle the debate about which one is the better choice for you. Here we go: Grammarly vs ProWritingAid!

Grammarly Cost & Features

Grammarly offers three subscription plans: free, premium, and business.grammarly vs prowritingaid

The paid plans take payments annually but are broken down into a monthly costs.

The free plan is, of course, free – at no cost to the user.

It includes the basics: spelling, grammar, and punctuation checks. It’s very similar to the spelling and grammar check on Microsoft Word or Google Docs.

The free plan also provides Grammarly site support and a Microsoft Word add-on which means you can integrate Grammarly into Microsoft Word, allowing you to use both checking systems at the same time.

Grammarly’s premium plan costs $11.66 per month, which calculates to $139.92 per year.

That number can be cringe-worthy; however, the premium plan includes everything in the free plan, plus full site access, and many in-depth features that allow users to be more specific about the type of document they want to design.

The premium plan will assist in creating the desired tone for documents, suggest new word choices, and adjust the level of formality. It also offers plagiarism detection.

The business plan costs $12.50 per month, which adds up to an annual total of $150.

It has the same exact features as the premium plan, except that it can be shared across a team of people.

The business plan is especially beneficial if you want one membership to be accessible by multiple people. It could be worth the money even if only two people are using it.

ProWritingAid Cost & Features

Similar to Grammarly, ProWritingAid also offers three subscription plans: free, premium, and premium plus. ProWritingAid is a slightly cheaper grammar checker than Grammarly, but it’s not safe to assume that the lower price equals a better choice.

ProWritingAid’s free plan offers basic spelling, grammar, and punctuation checks. However, it limits you to 19 writing reports, caps the number of words edited to 500 at a time, and the app is operable online only.

Upon upgrading to ProWritingAid’s premium plan, which is $79 per year, members keep all of the benefits of the free plan but drop all the limitations. There is no report limit, no editable word cap, and it’s even accessible offline.

The premium plan allows ProWritingAid to integrate with a myriad of web browsers and applications, such as Microsoft Word, Google Docs, Chrome, Scrivener, and many more.

The premium plus plan, $89 annually, includes everything in ProWritingAid’s premium plan, but only adds 50 plagiarism checks per year. Contrast this with Grammarly’s unlimited plagiarism checks with their premium and business plans.

ProWritingAid’s premium plus plan does not allow multiple users to share the membership.

Like most subscription programs, Grammarly vs ProWritingAid’s free versions can be a tease by only helping with a few obscure things. You won’t receive any help from either app if heavy editing and formatting are needed.

Although the site integration could be listed as a pro, neither app provides extensions that are extremely reliable. It is common for plug-ins to glitch and cause frustrations for the user.

Grammarly seems to be a tad more reliable than ProWritingAid.

Depending on the user, both grammar-checking apps can appear overwhelming because of the numerous features available.

Grammarly gives a good overview that can be clicked into for more details, while ProWritingAid shows too many features which can seem complicated for some people. This con is irrelevant to someone not interested in exploring all available features.
