By Jacob Maslow

When it comes to improving one’s writing, both ProWritingAid and Grammarly have become popular choices for writers, students, and professionals. These tools offer grammar checking, style suggestions, and editing assistance, but there are critical differences between the two that potential users should consider. This article will discuss the primary distinctions between ProWritingAid and Grammarly and help you decide which tool suits your needs.

ProWritingAid offers a more detailed writing analysis, boasting 20 reports that delve into structure, syntax, and style. On the other hand, Grammarly mainly focuses on punctuation, grammar, and clarity. The speed at which the tools provide feedback also differs, with Grammarly being faster, while ProWritingAid takes a bit more time to scan and prepare reports.

Another noteworthy difference is that ProWritingAid integrates with Scrivener, a popular writing software for novelists, screenwriters, and long-form writers. Grammarly, however, does not possess this feature. Both tools have browser plugins and desktop versions, catering to a wide range of users. In the following sections, we will examine these differences in depth, providing an informed choice between these two writing aids.

As a side note, I have been a heavy Grammarly Premium user for over three years and use it for all my writing. I am also an affiliate of Grammarly and Quillbot.

Prowritingaid Vs. Grammarly

Prowritingaid and Grammarly are popular tools designed to help writers improve their content quality. These tools focus on different areas of writing and can be helpful depending on individual needs.

Prowritingaid is known for its detailed analysis, offering 20 writing reports focusing on the content’s structure, syntax, and style. It provides in-depth explanations of its suggestions and helps writers improve their writing style. Prowritingaid has downloadable apps and extensions for Chrome and Safari, desktop apps for Mac and Windows, and a Microsoft Word add-in. However, its analysis might take a few seconds longer than Grammarly.

Grammarly, on the other hand, primarily focuses on punctuation, grammar, and clarity of content. Its suggestions are more straightforward and aimed at resolving simple errors. In addition, Grammarly offers real-time editing with its browser extension, allowing users to proofread and edit their content on various platforms and websites. It also has a mobile application for editing text on the go.

In terms of integrations, both tools have the following options:

  • Prowritingaid:
    • Chrome extension
    • Safari extension
    • Desktop apps for Mac and Windows
    • MS Word add-in
  • Grammarly:
    • Browser extension (Chrome, Safari, etc.)
    • Mobile application
    • Cloud storage for documents

To summarize this section, Prowritingaid and Grammarly are user-friendly tools catering to different writing needs. While Prowritingaid is more suitable for those seeking to enhance their writing style and structure, Grammarly is the go-to option for quick and efficient grammar and punctuation corrections.

Features Comparison

Writing Style and Suggestions

Both ProWritingAid and Grammarly offer suggestions to improve writing style and clarity. While Grammarly focuses on punctuation, grammar, and clarity, ProWritingAid emphasizes the content’s structure, syntax, and style. In addition, ProWritingAid offers more detailed analysis with 20 different writing reports, enabling users to dive deeper into the nuances of their writing.

Grammar and Spelling Check

Grammarly and ProWritingAid both provide grammar and spelling checks for users’ text. However, Grammarly stands out for its instantaneous result generation, identifying errors quickly and efficiently. On the other hand, ProWritingAid is slightly slower in scanning and preparing reports, taking a few seconds more to present the suggestions.

Plagiarism Checker

Grammarly and ProWritingAid offer plagiarism checkers, helping users avoid unintentional content copying or duplication. These plagiarism checkers scan articles for similarities with existing content, ensuring the work is original and unique.

Readability and Structure

ProWritingAid and Grammarly assess the readability and structure of the text, suggesting improvements to make the content more engaging and concise. Grammarly focuses on readability by presenting suggestions to break down complex sentences into simpler ones, reducing the overuse of certain words and phrases, and enhancing the overall clarity. ProWritingAid, on the other hand, extensively analyzes various writing aspects like sentence length, overused words, and passive voice construction, helping writers improve their text’s structure and flow.

Integrations and Supported Platforms

When comparing ProWritingAid and Grammarly, it’s essential to consider the integrations and platforms each tool supports, as this affects usability for the end-user.

ProWritingAid and Grammarly support popular word processors such as Microsoft Word and Google Docs. ProWritingAid can be used as a plugin on Microsoft Word, while Grammarly has a separate add-in for MS Word integration. For Google Docs, Grammarly provides a dedicated browser extension to make real-time editing and suggestions within the document. ProWritingAid also supports Google Docs through its browser extensions.

ProWritingAid offers a direct integration for writers who use Scrivener, which can be a crucial factor in choosing between the two tools. This allows Scrivener users to analyze their work from within the application easily.

Regarding websites and WordPress, Grammarly offers a browser extension that enables users to edit and proofread their content directly ( I use that on this site). This feature is handy for bloggers and content creators who want to avoid the hassle of copying and pasting their text back and forth between applications.

For browser extensions, both tools support popular platforms such as Chrome and Safari, with easy-to-install plugins. In addition, ProWritingAid Premium offers extensions for Chrome and Safari, while Grammarly has extensions for Chrome, Safari, and Microsoft’s Edge browser.

Lastly, when it comes to mobile apps, Grammarly has a clear advantage. Grammarly provides a mobile application that lets users proofread their messages, emails, and documents. Unfortunately, ProWritingAid does not currently offer a mobile app solution, limiting its usage for those who rely on mobile devices for their work.

In summary, ProWritingAid and Grammarly offer a range of integrations and supported platforms. Each tool has specific strengths. Whether you rely on Microsoft Word or Scrivener or need browser extensions for online editing, both tools can cater to your needs. However, for users who prioritize mobile functionality, Grammarly remains the standout choice.

Free Vs. Premium

When comparing ProWritingAid and Grammarly, it’s essential to consider their free and premium versions to understand their features and pricing better.

Free versions:

Both editing tools offer free versions with access to basic features like grammar-checking, spelling-checking, and punctuation. Here’s a quick look at the main features of their free versions:

  • Grammarly Free: Provides grammar checker, spell checker, and punctuation checker.
  • ProWritingAid Free: Offers a range of reports with a 500-word limit per analysis.

Premium versions:

To unlock more advanced features, users can opt for the premium versions of ProWritingAid and Grammarly. Here’s a breakdown of the key offerings for each premium version:

  • Grammarly Premium:
    • Price: Starts at $29.99 per month
    • Includes: Plagiarism checker, AI-powered writing assistant, and various other features aimed at enhancing your writing
  • ProWritingAid Premium:
    • Price: Currently unknown
    • Includes: No word-count limit for reports, in-depth feedback on your writing, accurate and easy-to-use functionality

While both tools have unique strengths and drawbacks, users should evaluate their needs and explore the free versions before deciding which premium offering best fits their requirements. Remember, always prioritize accuracy and clarity when choosing between the two platforms.

Pricing and Plans

When comparing ProWritingAid and Grammarly, it’s essential to consider their pricing and plans.

  • ProWritingAid:
    • Offers affordable options for users.
    • The premium plan provides added features at a competitive price point.
    • $120 per year if paid annually, $399 for a lifetime subscription, and a $30 monthly option.
  • Grammarly:
    • The premium version has three individual payment plans:
      • Monthly at $30
      • Quarterly at $20/month, billed as $60 (the plan I have used since January 2020).
      • Annual at $12/month, billed as $144
    • Grammarly Business pricing:
      • $29.99 per month per user
      • Based on the number of people on your team

In terms of affordability, ProWritingAid is often regarded as the more cost-effective option. This is particularly true when considering the lifetime plan, which doesn’t have an equivalent in Grammarly’s pricing structure. Moreover, ProWritingAid’s pricing appeals to a wider range of users, including students, writers, and professionals.

However, considering Grammarly’s advanced features and accuracy, users may find its pricing justifiable. Grammarly’s 400+ error-checking factors and ease of use make it a powerful option for those willing to invest in its higher-pricing plans. Furthermore, Grammarly Business may be beneficial for collaborative teams and organizations.

Overall, the pricing and plans of both ProWritingAid and Grammarly cater to different user preferences and needs. Therefore, weighing the affordability against the features provided by each tool will help users make an informed decision on the best-fit software for their specific writing requirements.

Accuracy and Performance

Grammarly is known for its accuracy and quick performance. It scans a piece of writing and reorders sentence structure to make it more straightforward for the reader. Over time, this tool has become more accurate, ensuring a higher level of error-free writing for users. However, one downside is that it can be less useful for long-form writing and fiction.

On the other hand, ProWritingAid offers more detailed reports and in-depth analysis of writing. For example, it provides 20 writing reports, more than any other marketing grammar checker. This makes ProWritingAid particularly useful for users looking for that extra layer of feedback and suggestions.

Both tools perform well in readability, but Grammarly offers more instantaneous suggestions. This ensures that users can make their writing more readable without spending too much time reviewing suggestions. On the other hand, ProWritingAid can sometimes be a bit slower in providing recommendations, which might be a drawback for some users.

As for accuracy, both Grammarly and ProWritingAid have their strengths. While Grammarly excels in providing fast, accurate suggestions for sentence structure and grammar, ProWritingAid delves deeper into the analytics, offering a more detailed report on the user’s writing style and areas for improvement.

In conclusion, both tools effectively enhance the accuracy and performance of users’ writing. Grammarly is an excellent option for those looking for fast, accurate suggestions, while ProWritingAid is better suited for users who want a more comprehensive analysis of their writing.

It utilizes artificial intelligence and machine learning to help users rewrite their content while maintaining the original meaning. This can be advantageous for those who require assistance in rephrasing or rewording sentences, especially for academic or professional work.

The grammar-checking feature of Quillbot is not as advanced as Grammarly’s; however, it is efficient enough for proofreading content before submission or publication. In addition, the tool supports different English dialects, such as American, British, and Australian English, which helps identify and correct spelling and grammar errors accordingly. Regarding grammar correction, it performs better than built-in checkers in applications like Google Docs and MS Word.
