DisclaimerPlease note: This article was written in November 2022. Changes to LanguageTool’s and ProWritingAid’s functionality may occur in the future.
LanguageTool and ProWritingAid are intelligent writing assistants. They are tools that help refine your writing by detecting and correcting errors in spelling, grammar, punctuation, and more.
Are you stuck deciding between the two? Below, we’ll go over five strengths that LanguageTool has over ProWritingAid.
Benefits of Using LanguageTool
1. LanguageTool detects more errors than ProWritingAid
Regarding spelling and grammar errors, ProWritingAid does, in fact, detect the obvious errors. However, not only does LanguageTool detect more spelling and grammar errors, but it also suggests stylistic improvements. Take a look at the following example:
LanguageTool detects 12 errors in spelling, grammar, punctuation, and word choice.ProWritingAid only detects five mistakes—all of which are grammar-related.
The types of mistakes LanguageTool detected that ProWritingAid did not include:
punctuation errors (missing comma after designing)
complex grammar rules (subject-verb agreement)
inconsistencies caused by dialects (jewellery → jewelry)
LanguageTool also provides style suggestions:
a lot of hours → plenty of hours
Splitting up a sentence that has over 40 words
ProWritingAid also provides style suggestions, but one of them convolutes the sentence by suggesting to remove “that” in the following sentence:
“… there’s just something about the smooth flow of ink on crisp, clean paper that helps rev up my creative engine…”“… there’s just something about the smooth flow of ink on crisp, clean paper helps rev up my creative engine…”
2. LanguageTool has more transparent privacy policies.
According to its website, ProWritingAid processes and stores data (including what you write) on servers hosted in the United States. LanguageTool, on the other hand, only processes data for improving their corrections.
Additionally, although LanguageTool offers rule-based and artificial-intelligence-based checking, it’s also open source—meaning people from all over the world can contribute to LanguageTool, which allows rapid growth and development.
3. LanguageTool supports multiple languages and dialects.
ProWritingAid only supports “General English” and some of its dialects including British English, US English, Australian English, and Canadian English. Not only does LanguageTool support these dialects, but it also supports New Zealand and South African English.
Moreover, LanguageTool is multilingual. It can detect spelling and grammar errors in over 25 languages including German, Spanish, French, Dutch, and Portuguese. ProWritingAid only checks for spelling and grammar errors in English.
4. LanguageTool has a rephrasing feature.
Enhancing your writing is much more than just correcting errors. LanguageTool can take your writing to the next level by helping you rewrite sentences to better suit your audience. The rephrasing feature rewords your sentences to be more formal, fluent, concise, or simple. As of now, ProWritingAid offers no such feature.
LanguageTool’s rephrasing feature helps get the exact tone you’re aiming for.
5. LanguageTool is more user-friendly.
LanguageTool’s interface is designed to provide distraction-free writing, whether you’re using the desktop or online editor. ProWritingAid’s editor has many icons and colors, which might make it difficult for some people to focus.
LanguageTool also provides more plug-ins and add-ons, which means more possibilities of seamless integration regardless of your favorite app or program.

LanguageTool is an advanced writing assistant that goes beyond simply checking for (and correcting) grammar, spelling, and punctuation mistakes. Instead, it analyzes your writing entirely to provide suggestions that significantly elevate your texts. For example, style suggestions can enhance the flow, clarity, and readability. If a sentence is too long, if the passive voice has been misused, or if there are better alternatives to a wordy phrase, LanguageTool will notify you.
LanguageTool does much more than correct grammar, spelling, and punctuation errors.
Furthermore, if you’re seeking a certain tone for your writing, but can’t seem to find the right words, LanguageTool’s rephrasing function can rewrite your sentence to better suit your audience’s needs.

Long sentences can leave your readers confused, or worse, they can cause them to stop reading your writing altogether. That’s why LanguageTool developed a feature that can detect long sentences and propose two shorter, split sentences.
This guide will go over everything, including what LanguageTool is, the issue with long sentences, and how to use the innovative sentence-splitting feature.
LanguageTool is a powerful writing assistant that enhances your text by correcting a wide range of errors and offering stylistic suggestions that improve the tone, flow, and readability. With support for over thirty languages and dialects, this powerful grammar, spelling, and punctuation checker can be used across multiple platforms including Mac and Windows apps, the online editor, and various add-ons and plug-ins.
Red notifications are spelling errors; yellow are grammar mistakes; purple are style suggestions; and blue are rephrased sentences.
Picture this: You’re an aspiring author working on a romantic fiction novel. You’re using an AI writing assistant to help rid your text of grammar and spelling errors. Occasionally, though, the writing assistant offers suggestions to paraphrase and “improve” your work. Out of curiosity, you view the suggestion, and it offers to “fix” it by rewriting poetic, awe-inspiring prose into a stiff, serious text. In dismay, you turn off the writing assistant because what’s the point?
LanguageTool understands that no two texts are the same. The Writing Goals feature lets you customize your experience so that you only get suggestions that fit your writing needs.
This is a game changer for all types of writers, whether you’re working on an academic paper, a work report, a creative project, or anything else. Below, we’ll show you how to use this writing feature and which writing goals you can choose from.

It’s not every day that one bears witness to the birth of a technology that will undoubtedly change the world and the way we live in it. For years, we’ve watched movies and shows about artificial intelligence. Still, those were always considered science fiction—just a figment of someone’s imagination of how things could be in the future. But that future is here now.
With the rise of artificial intelligence comes the need to learn new ways of doing things we’ve been doing all along—like using the written word to express our thoughts.
Helping us strengthen our writing is just one of the many ways in which artificial intelligence can be helpful. But it’s not as easy as asking it to generate a text for you, as doing this can be problematic. That’s why we will teach you how to correctly use ChatGPT along with LanguageTool to generate compelling, error-free writing.
Before we do that, let’s cover some basics, like what LanguageTool and ChatGPT are and why you should avoid using artificial intelligence to generate your entire text.
