Prowritingaid vs Grammarly

For over a year now, I've been using both the free and premium versions of Grammarly and ProWritingAid.

While I use the Grammarly Windows desktop app almost daily, I use ProWritingAid 3-4 times a week while revising long-form articles and blog posts.

So, I thought of creating a detailed comparison of ProWritingAid vs Grammarly for people looking to improve their day-to-day writing.

What is Grammarly?

Grammarly is a grammar checker, style editor, and plagiarism checker available as a native app for Windows and Mac and has browser extensions. Grammarly can help with all types of business writing as well as academic writing.

What is ProWritingAid?

ProWritingAid is an online editor, writing mentor and style editor that scans your text for grammar mistakes, potential stylistic mistakes, and other features of interest. Whether you're a blogger, novelist, SEO professional, or student writing an essay for school, ProWritingAid can take your writing to the next level. 

Feature-by-feature comparison: Grammarly vs ProWritingAid 

1. Grammar Assistance


Grammarly works by comparing your writing to its internal database of more than 250 million published documents across the web, including books from Amazon. The software uses statistical analysis to determine if the way you are using words is appropriate for the context in which you're using them.

Grammarly checks for periods, ellipses, commas, apostrophes, exclamation points, question marks and dashes etc., to ensure that your punctuation is always correct. Less commonly used punctuation marks such as Interrobang, Brackets etc., are also incorporated. Having my punctuation taken care of by Grammarly allows me to direct my writing flow, showing my readers where to pause and where to stop. This helps in interpreting the text easier for the reader.


ProWritingAId provides 20 writing reports that help you find inconsistent writing and repetition, awkward sentence structure, etc. The software can highlight spelling errors, which are highlighted in red. Misspelt and commonly confused words in the English language are pre-programmed to help you figure out when you make a mistake, such as a wrong usage.

The grammar checking tool in ProWritingAid is robust and built to be as similar to popular word processing programs as possible. ProWritingAid's grammar checker includes many options for fixing important grammar errors, such as Subject/Verb agreement, Possessive nouns not followed by a gerund form of a verb and Unclear pronoun references.

The punctuation corrector software detects punctuation errors such as comma splices, apostrophes and semicolons. ProWritingAid highlights punctuation errors in orange and blue. The errors are also accompanied by an explanation to help you get a better understanding of the rules in the process. This helps avoid repetitive mistakes.

Verdict: ProWritingAid is slightly better than Grammarly at Grammar Assistance

The two software are almost on par with each other. I slightly favour ProWritingAid versus Grammarly because of the more extensive range of reports available that allow you to go beyond just grammar and infuse an element of learning for the user.                                     

Winner: ProWritingAid (9/10)

Loser: Grammarly (8.5/10)

2. Writing Style Assistance


The writing style is influenced by a multitude of writing choices. But word choice and structure are arguably the most significant when it comes to defining your writing style. 

Word choice options in Grammarly suggest vocabulary enhancements that help you find the right words. The suggested words are context-optimized to ensure the correctness of meaning in a given context.

Grammarly is also highly customizable, allowing you to deactivate or activate specific suggestions as you see fit.

You can also choose whether you are a Student or a Teacher, a Business Professional, a job applicant, an Author, a Medical professional, a Blogger or a Technical Writer, and Grammarly will suggest an editing style catered to the specific needs of your profession. 

Grammarly style guide is available in the business version. The features in the style guide allow you to use shared words, phrases and terms specific to your team or organization. It can help you replace acronyms and jargon by creating rules. It also remembers company names, product names, and trademarked names to ensure proper spelling and capitalization. Grammarly Business allows you to create and update custom style guide rules.


The Word Explorer feature in ProWritingAid analyzes your work and highlights various potential problems, including overused words, abstract language, passive voice, punctuation difficulties, and more. You can also look at how you employ word lengths, sentence lengths, transitions (words like "however" or "moreover" that introduce a new point), pronouns and articles (a/an/the), and filler words. Overused terms are highlighted in blue in ProWritingAid, so you can readily spot them wherever they appear in your work.

ProWritingAid offers an interactive style guide that can help you remove errors in your writing efficiently. 

By default, ProWritingAid offers several prebuilt writing styles.

  1. General style: It checks for capitalization and punctuation marks and helps you convey emotions in your writing. This style avoids Business jargon and suggests replacements.
  2. Academic style: It suggests simple sentences with grammar rules while allowing you to use passive voice, which is often used in academic writing.
  3. Business style: It checks for offensive or Discriminatory language, email style rules etc. 

Apart from these rules, there are many other writing styles available in ProWritingAid, including, Technical, Creative, Web, Script etc. 

You can also create custom style guides tailored to your writing needs and dispositions.        

Verdict: ProWritingAid is slightly better

ProWritingAid and Grammarly are both great options for enhancing and accomplishing your writing style goals. Both offer a lot of room for customization according to your needs. I think ProWritingAid is slightly more customizable and offers more space for personalization. 

Winner: ProWritingAid (9.5/10)

Loser: Grammarly (9/10)

3. Plagiarism Detection

Both ProWritingAid and Grammarly have excellent plagiarism checkers. However, they differ in price and features.


ProWritingAid's Plagiarism Checker uses the same database as Turnitin (the industry-standard plagiarism checker). This means that it's a great way to double-check your work before submitting it to instructors who use Turnitin. Because of this, all students can benefit from using ProWritingAid's Plagiarism Checker.

A free edition of ProWritingAid allows you to perform 25 checks every month. If you use ProWritingAid after the free trial period, you will be prompted to pay for a membership, starting at $40 per year.

For example, running two different types of analysis (such as spelling and grammar) at the same time would count as two checks. However, given you were using the same file for both analyses, if you ran spelling first and then grammar without restarting your document from scratch (which does not count as another check), it would only count as one check. This means that the majority of customers will have no trouble meeting their monthly quota.


Grammarly's plagiarism checker is just as effective as ProWritingAid, but it doesn't use the same database as Turnitin. Therefore, there's a chance that you won't catch all instances of plagiarism if you submit work that you've checked with Grammarly to an instructor who uses Turnitin. However, if your purpose is only to catch plagiarism in your own writing rather than checking against other works, then Grammarly will serve you well.

Verdict: Grammarly is better then ProWritingAid at Plagiarism Detection

In conclusion, there is one notable advantage that Grammarly has versus ProWritingAid: Its premium plan allows users to upload unlimited word documents into their dashboard for easy checking and correction on the go. 

Winner: Grammarly (9/10)

Loser: ProWritingAid (8/10)

4. Pricing


The Standard version of ProWritingAid costs $20 per month, while the Premium version costs $34. For either package, the Chrome plugin costs $20. A yearly membership to the ProWritingAid web editor costs $59 for the standard edition and $66 for the premium version. You can save 20% on an annual subscription package if you are a student or teacher.

Prowritingaid has three programmes for people and three for businesses, but they also have discounted pricing for students and teachers. The ProWritingAid web editor comes with a 14-day money-back guarantee, so if you don't like it, ask for a refund within 14 days of purchase.

Prices for the basic plan in ProWritingAid:

Pricing for the ProWritingAid premium plan:


Premium Plan

Grammarly Premium can be purchased monthly, quarterly, or annually. The following is Grammarly's regular pricing: Each month's subscription is $30. The cost of a three-month quarterly subscription is $60 (billed as one payment). A one-year subscription costs $144 (billed as one payment)

Business Plans

Grammarly Business provides monthly and annual memberships for teams of three or more. The membership cost is $25 per month for each member (billed as one payment for all users). The number of users on your team determines the annual subscription fee. In 3–9 member teams, each member pays $12.50 each month, teams with 10 to 49 members pay $12.08 per month, and teams with 50 to 149 members pay $11.67 per month.

The prices listed are for the average monthly cost per user; however, the annual plan is paid in one lump sum for all users.

Conclusion: Both ProWritingAid and Grammarly are at par

Both ProWritingAid and Grammarly have free plans, but ProWritingAid's free plan only allows you to check 500 words at a time and gives you 19 reports. Grammarly's free version has some limitations, but you get a lot more out of it, and you can even install the Chrome extension. Both paid plans are top-notch, and they have apps for pretty much any device you own. However, only ProWritingAid allows you to integrate with Scrivener, a screenwriting and book rating app. 

Grammarly premium has a limit of 150 000 words per month, which is relatively high, whereas ProWritingAid premium users have limitless checks. Once again, it's a tie, but the free version of Grammarly is the best choice in the category, but if you are looking for premium services, ProWritingAid might be the best alternative. 

Winner: ProWritingAid (8.5/10)

Loser: Grammarly (8/10)

5. Platform Integration


ProWritingAid works on Mac, Windows, and Linux (as well as online). ProWritingAid can be installed as a standalone program (Mac, Windows, and Linux) on your desktop. It can also be used to enhance your favourite word processor so that you don't need to switch between tools. Alternatively, users can upload files from their computer to the online editor for deep analysis of more than 20 different reports.

The free version has MS Word and Google Docs interfaces, which is excellent for anyone who changes documents on those platforms. These allow you to double-check your work with a single click and use features like the contextual thesaurus and vocabulary builder.

The only drawback: You're only allowed to alter texts up to 20,000 words every session, and you can only check 25 documents per month.

You can also combine it with Scrivener, Open Office, a Google Chrome extension, and MS Outlook with the premium edition. There is even an HTML editor option for combining the programme with internet sites such as WordPress, Medium, or Gmail.

To use many of the ProWritingAid website capabilities, the ProWritingAid text processing API provides a simple RESTful interface with lightweight JSON-formatted responses. This document explains how to interact with the ProWritingAid API to have access to our advanced text processing API for developers.


Grammarly is available on Windows, Mac, Android and iOS. You can also integrate Grammarly with various browsers such as Chrome, Safari, Firefox and Edge. Grammarly seamlessly integrates with Microsoft Office and Google Docs. 

Grammarly can also be integrated with Slack, Skype, Apple Mail and Discord. You can add real-time writing capabilities to your app with the Grammarly Text Editor SDK by adding only a few lines of code. This feature allows you to deliver comprehensive suggestions quickly on your web applications. This can make writing easier for your end-users and assist writers of all skill levels. 

Conclusion: Both ProWritingAid and Grammarly are at par

Both Grammarly and ProWritingAid can sync your account across devices which is a huge help if you travel with multiple devices.

ProWritingAid has one feature that I wish was included in Grammarly: real-time collaboration (similar to Google Docs). Unfortunately, this feature is only for paid Premium members. I think it would be a fun way to write together if you are working with another writer on a joint project or even just when writing blog posts together.


Winner: ProWritingAid (9.5/10)

Loser: Grammarly (8.5/10)

6. Support

The primary source of customer support in both ProWritingAid and Grammarly is the blogs and FAQs available on their respective platforms. Other than that, several independent blogs exist to walk you through the various processes and features. If you need more assistance, you can contact the respective customer support teams through email. I found this feature very useful as sometimes it's difficult to find content on the exact problems that you face.

Conclusion: Both ProWritingAid and Grammarly are not so good

Because neither ProWritingAid nor Grammarly provides a live chat feature, you must submit a question and wait for an email response. I had to wait almost a day for a response from Grammarly, but their tone was kind and friendly. ProWritingAid, on the other hand, took an hour to respond to my email and also composed a thoughtful and professional response. Grammarly's customer support was adequate, but if you're in a rush and require immediate assistance, ProWritingAid can save you time and effort.

7. Language Preferences

This is not much of a contest; both Grammarly and ProWritingAid are available in English only. So, this might not be the best choice for multilingual users to check for grammar in multiple languages. However, there are other options you could try, such as white smoke or ginger.

What are the other alternatives to Grammarly and ProWritingAid? is artificial intelligence (AI)-powered writing assistance. It aids in the creation of SEO-friendly blog posts, social media postings, Facebook ads, YouTube video descriptions, product reviews, and Quora comments. The platform is backed by paper content, already well-known in the content writing sector. SEO (search engine optimization) Beginners will enjoy it. However, the  Pricing might be too high for some users, and  When the editor generates a mix of languages, it can be a little unattractive.


Outranking is a content editing and writing programme powered by artificial intelligence. Training AI to extract sentiments and provide factual material is one of its features. analyzes other high-ranking posts and extracts the best elements. Content editors and AI text production are available. There is no limit to the amount of AI content you can create. Some cons I found are that The user interface is still in its infancy, and at times the target keywords are incorrect.


INK for all is a platform that uses artificial intelligence to create and modify content for social media, business, marketing, sales, and even personal projects. Both content writers and SEO professionals will find it useful. A copy can be generated automatically and adjusted for search engine compatibility using the AI writing helper. AI Text production and content editing are both available on this platform. It also offers a no-cost package. One problem that I faced with INK is that only about 30 words are generated at any given time.

Grammarly vs Prowriting Aid: Which one is best for me? 

Both ProWritingAid and Grammarly are excellent writing assistants, and finding a clear winner is a difficult task even for me. But some things are just better in one application than the other. And based on these I will help you choose the best. 

If you are looking for a tool to help you improve your grammar and stylistic errors, ProWritingAid performs slightly better than Grammarly with its wide range of reports and customizations. The plagiarism checker is marginally better in ProWritingAid compared to Grammarly, but it's limited in the number of words that you can check. 

In terms of pricing, the free version of Grammarly is better than ProWritingAid, offering unlimited document upload and chrome integration. But if you are a user who wants to pay for writing assistance services, ProWritingAid can offer more. 

Both applications can be integrated with different platforms, but in this regard, ProWritingAid has the edge, especially for Businesses and Teams. 

Based on the various features, pricing, and support, I think ProWritingAid has a slight edge over Grammarly, especially when it comes to the premium plans. I feel that ProWritingAid offers a little more in terms of quality.
