Grammarly vs ProWritingAid Video Review 

If you are a video person, here’s my video review of Grammarly vs ProWritingAid. It’s in the Hindi language with English subtitles. Hope you enjoy watching!

User Interface – Grammarly vs ProWritingAid

 User Interface – Grammarly

The user interface of Grammarly is modern and elegant. All the options and settings are neatly arranged on the left sidebar. The main screen comprises a list of your edited documents.


To create a new document, you need to click on the ‘New’ icon. It also lets you upload documents to its editor. However, importing documents via a link is not possible.

Its editor interface is quite simplistic as well. The right panel displays your document score and relevant corrections. The bottom bar has basic formatting options to edit your document in the Grammarly editor.

Grammarly Editor Interface

You might find a few formatting issues on Grammarly editor. For instance, copying the edited document and pasting it into a different editor disturbs the spacing. Also, if you had images and tables in your document, they are removed as you paste the content on Grammarly.

The Grammarly editor dramatically slows down with long-form content over 4k words. But overall, the interface of Grammarly is pleasing and friendly for newbies.

User Interface – ProWritingAid

The interface of ProWritingAid is simple and clean, but slightly old-fashioned. The main screen displays a list of your recent documents. 

ProWritingAid User Interface

To create a new document, you can click on the ‘New Doc’ button on the left panel. It supports uploading documents but importing them via links is not allowed.

The ProWritingAid editor is decent. The upper panel comprises all the detailed reports you can use to check your content. 

ProWritingAid User Interface

The right panel shows your goals, document score, and suggestions. Unlike Grammarly, the formatting options on ProWritingAid are visible once you select the content you want to format.

You may face issues while copying and pasting images and tables in the editor. But overall, the interface is clean. The dozens of reports make it a little complex for a beginner. 

It has a small learning curve. So, once you invest a few hours in understanding all its features, you will realize the true power and value of ProWritingAid.

Winner – Best User Interface

Although both the tools have elegant and friendly interfaces, ProWritingAid has a small learning curve. Thus, Grammarly is the winner here.

The Content Score on Grammarly is available in the top right corner. You can click on it to view your overall performance.

Talking about reports, Grammarly displays details about your document’s performance, word count, and readability. The design of its report is quite clean and easy to understand.

Winner – Best Content Score and Reporting

Grammarly offers surface-level reports on the content. Whereas, reports offered by ProWritingAid are far more detailed and helpful for improving your writing. Hence, ProWritingAid is the winner here.

Real-Time Suggestions Grammarly vs ProWritingAid

Real-time Suggestions Grammarly

Because Grammarly does not have a report-based system, it shows all the suggestions found throughout the document on the right side of the editor.

Grammarly - Real time Suggestions

As you keep on accepting the changes suggested by it, your document automatically keeps on scrolling down to the next error spot, which is a very convenient feature. 

Real-time Suggestions ProWritingAid 

ProWritingAid works on the report-based approach, so you won’t find a lot of suggestions in the Real-time mode. You need to separately check out the relevant reports to make edits to your content.

ProWritingAid - Real time Suggestions

It also does not display all the real-time suggestions at once. As you keep scrolling down the document, it only shows the suggestions in their respective places. You can click on the downward arrow on every suggestion to accept/reject it and move to the next one.

Winner – Best Real-time Suggestions

Grammarly wins at real-time suggestions as it makes it easier and more convenient for users to find all grammar errors in one place. This is best if you wish to edit shorter documents.

Spelling and Grammar – Grammarly vs ProWritingAid

Spelling and Grammar – Grammarly

In Grammarly, you can spot spelling, punctuation, and grammar mistakes in the Correctness tab. My test document offered 6 suggestions for correctness. All of them seemed very logical, for instance, adding punctuation, first letter capitalization, etc. 

Grammarly - Spelling and Grammar Suggestions

You can also add certain spellings to your personal dictionary. These words won’t be marked as errors when you refresh the page.

Spelling and Grammar – ProWritingAid

Grammatical errors and spelling errors can be spotted under the Grammar tab. Our test document suggested 10 grammatical errors. 

ProWritingAid - Spelling and Grammar Suggestions

These included the usage of punctuation and first letter capitalizations. However, most of the suggestions offered by ProWritingAid were very different from Grammarly. 

Winner – Best Spelling and Grammar

Overall, Grammarly and ProWritingAid pointed out very different errors in spelling and Grammar. But both of them were logical and accurate in their own ways. Thus, this round is a draw between them.

Content Clarity – Grammarly vs ProWritingAid

Content Clarity – Grammarly

Under the Clarity tab in Grammarly, you will find suggestions to make your content easier to read and more clear for your audience. This includes changing the wording of the used phrases or rephrasing the sentences entirely. 

When I pasted my test document in the Grammarly editor, it offered 28 clarity suggestions.

Grammarly - Content Clarity

Overall, the suggestions are logical and relevant. However, the best thing about its full-sentence rephrasing feature that helps maximize clarity. Unlike ProWritingAid, it rephrases the entire sentence automatically and all you need to do is hit the Accept button to implement it. 

Content Clarity – ProWritingAid

In ProWritingAid, the Style, Readability, and Sticky Sentences reports can be optimized to improve content clarity. When I pasted my test document in its Editor, I found 29 suggestions in total under these 3 reports.

ProWritingAid - Content Clarity

These included suggestions for improving my content’s readability, style, word choice, and passive voice. It also identified sticky sentences and difficult-to-read sentences. Grammarly doesn’t offer such detailed suggestions.

The readability report shows the Flesch reading score of a sentence and the sticky sentences highlight the sticky words used in your sentence. This helps you simplify wordy sentences. 

However, unlike Grammarly which rephrases your complex sentences, you need to rephrase your sentences by yourself on ProWritingAid. It won’t rewrite them for you.

Winner – Best Content Clarity

Grammarly offers you full-sentence rewrites. Whereas ProWritingAid comes with advanced and more intricate suggestions related to language. Both are powerful features on their own. Hence, it’s a draw for this category.

Tone Detector – Grammarly vs ProWritingAid

Tone Detector – Grammarly

Grammarly offers a Tone Checker on its free and Premium plans that help you understand the tone of your content through helpful emojis.

Grammarly Tone Detection

It offers a variety of tones, including friendly, confident, excited, appreciative, formal, concerned, etc.

Tone Detector – ProWritingAid

Unfortunately, ProWritingAid does not provide any such functionality on its platform.

Winner – Best Tone Checker

Without a doubt, Grammarly is the winner in this category because ProWriitngAid doesn’t have this tool.

Plagiarism Checker – Grammarly vs ProWritingAid

Plagiarism Checker – Grammarly

The Premium version of Grammarly offers unlimited plagiarism checks. However, the quality of plagiarism checking is average.

Grammarly Plagiarism Test

It simply points out the plagiarised phrases along with the percentage of plagiarism in every phrase or sentence. It does not provide any in-depth data on the plagiarised content.

Plagiarism Checker – ProWritingAid

On ProWriitngAid, the Plagiarism checks are only available in the Premium Plus plan. On this plan, you can perform 60 plagiarism checks/year, which is quite low.

Winner – Best Plagiarism Checker

Overall, the winner of this round is Grammarly because even though the quality of plagiarism checks is average, it doesn’t impose any limits on plagiarism checks per month.

Limitations – Grammarly vs ProWritingAid

Limitations – Grammarly

Even though there is no strict limit on Grammarly Premium, you can only check up to 300 docs or 150k words in 30 days. This is done to prevent the overuse of this tool.

Limitations – ProWritingAid

ProWritingAid offers no restrictions. You can create unlimited documents and check an unlimited number of words every month.

Winner – Least Number of Limitations

ProWritingAid wins in this case because it does not have any hard limit on the number of documents or word checks in a month.

The free version of Grammarly gives you access to basic grammar suggestions. This comprises spelling, grammatical errors, punctuation, and clarity. It does not pose any limit on the word count of checking.

Grammarly Free plan

Apart from that, it also performs live tone detection as you type in your content on various online apps. It displays how your content sounds to readers via helpful emojis.

This helps you edit your content in a detailed and precise manner. However, you can only check up to 500 words at a time.

Winner – Best Free Version

Customer Support – Grammarly vs ProWritingAid

Customer Support – Grammarly

Grammarly offers a chatbot and email support to its users. I found its email support to be pretty knowledgeable and polite. They usually respond to email queries within 12 hours.

Grammarly Knowledge base

They also have an extensive knowledge base of helpful articles and a blog full of insightful posts on language, grammar rules, and their correct usage. However, you won’t find live chat support in Grammarly.

Customer Support – ProWritingAid

ProWritingAid provides email support to its customers that functions from Monday through Friday between 8 A.M. to 5 P.M. 

ProWritingAid Support

They also feature FAQ questions, lots of writing resources, a Grammar Guide, and a rich blog with helpful articles on grammar and language. However, they also don’t offer live chat support to their customers.

Winner – Best Customer Support

Both the tools offer email support, a decent knowledge base, an informative blog, and lack live chat support. Thus, it’s a draw for this category.

When Should You Use Grammarly?

Grammarly would be your best option when dealing with short-form content like emails, notices, social media posts, product descriptions, etc. It comes with functional extensions and apps for all devices, which make it accessible anywhere and anytime.

It’s an easy-to-use tool that can proof your content quickly and accurately. For more details, you can also read my Grammarly Review.

When Should You Use ProWritingAid?

ProWritingAid is best when you’re dealing with long-form content (over 1.5k+ words) like blog posts, books, reports, academic papers, etc. You will experience the actual power of ProWritingAid’s reports with long-form content.

Although it demands a slight learning curve, it is worth it if you are a content writer or someone who works with lengthy texts regularly. For more details, you can check out my ProWritingAid Review.
