Features of Grammarly

Goal Setting

Tone Detection

Probably one of my favorite features as an author. Grammarly offers genre-specific writing style checks through its goal-setting feature. It’s one of the core features of this grammar application that makes it unique from the others.

Set the intent, emotion, audience, and domain of your writing so the suggestions will be relevant to these needs. Goal-setting also encourages Grammarly to conduct more accurate grammar checks based on every writing project’s requirements.

Grammar and Spelling Check

2022 06 07 1

Grammarly is the most popular tool for conducting spelling and grammar checks because of its advanced suggestions. Aside from basic spelling and grammar mistakes, it also corrects advanced language mistakes like wordy sentences and the passive voice.

The grammar corrector offers clarity-focused sentence rewrites too. It shortens your sentences for readability without removing their meaning or intent. Grammarly Premium also provides suggestions for confident writing, politeness, and sentence variety.

Accept Grammarly’s suggestions until the performance score on the upper right shows 100.

This accurate grammar checker uses AI technology to spot all advanced writing clarifications. You won’t find these recommendations from other grammar checkers. And that’s why Grammarly is everyone’s favorite writing assistant.

Plagiarism Detector

Plagiarism Checker

One of the most special features of Grammarly Editor is its built-in plagiarism checker on the premium version. It compares your work against online and offline sources, looking for duplicate content or any form of unoriginal content.

Only a few grammar programs offer this type of plagiarism checker. But Grammarly requires a subscription so that users can access this feature.

Multiple Platform Availability

Grammarly gives basic grammar corrections across different platforms so you don’t have to switch between apps. Although it has its own desktop app and web editor with a clean interface, the browser extension will save you more time proofreading.

Install the helpful content editor on Google Chrome, Safari, Firefox, and Microsoft Edge so you can use it on different websites. Grammarly will underline any writing error you make as you type on email, social media, or Google Docs.

Grammarly also has an MS Word add-on and a Grammarly Keyboard for mobile users.

Features of LanguageTool

Grammar and Spelling Check

LanguageTool Grammar and Spelling Check

Although the writing assistant does not give advanced reports, the suggestions are highly accurate compared to other programs. Use the English grammar checker to proofread your academic and company documents for smooth writing.

LanguageTool also gets plus points for detecting overlooked writing errors like hyphenation. This feature will help you understand when to add a hyphen, em dash, or em dash to your words. 

English Variations

LanguageTool English Variations

Besides adhering to basic grammar rules, LanguageTool also offers detection of English language variations. Its ability to give you the correct spelling for British or American English promotes brilliant communication between the reader and writer.

It’s one of the most advanced features for writers who write for different audiences. LanguageTool uses artificial intelligence technology to fix this writing style subject. For example, if you select American English, the tool will flag “theatre” as a misspelling.

Multiple Languages

LanguageTool Multiple Languages

LanguageTool stands out in its multilingual feature. It ensures efficient communications between the writer and the audience by conducting a comprehensive review of your writing. No matter the language, this grammar checker tool can perfect your writing.

Many grammar tools do not offer this type of language tool. LanguageTool detects grammar errors in over 20 languages, including Persian, Slovak, French, Japanese, Italian, and German language. 

LanguageTool also spots some errors in spelling in different languages. Overall, its error detection in multiple languages is adequate. Use it as an everyday language checker for your casual writing.

Personal Dictionary

LanguageTool Personal Dictionary

Besides LanguageTool’s comprehensive features for grammar and spelling mistakes, it also has a customizable dictionary. You can add new words, made-up words, names, and other terms.

The next time you use these words, LanguageTool won’t give basic writing suggestions for them as “misspellings.” The grammar checker software excludes the word from possible spelling and grammar rules that might apply to the text. 

Platform Availability

Users like LanguageTool because they can use it as a browser extension for Chrome, Firefox, Docs, Word, and LibreOffice. Proofread your work directly on these applications, so you don’t have to switch between apps when editing.

Grammarly vs. LanguageTool: Free Version

Take a look at how Grammarly and LanguageTool compare against each other when it comes to their free versions.

Suggestions

Both Grammarly and LanguageTool provide similar suggestions for spelling and grammar on their free versions.

Grammarly Free helps you improve your grammar, spelling, and punctuation. But it won’t offer consistency in spelling and punctuation. It also doesn’t provide clarity-focused rewrites and vocabulary enhancements.

LanguageTool Free only offers basic suggestions for your grammar and style. But the free version won’t make your text look more readable and professional.

Character Limit

LanguageTool’s free version only checks up to 20,000 characters. This might be a dealbreaker if you’re a novel writer or long-form content writer. 

Try Grammarly if you want a free app that offers unlimited checks. This tool offers limitless grammar checks with no word or character limitations. 

Multilingual Feature

LanguageTool offers basic free grammar checks in different languages, including French, Italian, and German. But you need to subscribe to the premium version to receive 5,000 more checks.

Grammarly Free doesn’t conduct grammar checks in any language other than English. Even if you subscribe to the premium version, the grammar checker will not proofread content written in a foreign language.

LanguageTool vs. Grammarly Verdict

Writers need an accurate grammar checker to produce error-free content. Two online tools you may consult are LanguageTool and Grammarly.

Both writing assistants have their own pros and cons, but Grammarly is a more accurate and reliable tool you can try. It can correct more in-depth grammar mistakes like unclear sentences, wordiness, and improper tone.

But if you’re looking for a grammar checker with multilingual support, download LanguageTool. It offers grammar checks for foreign languages at a more affordable price.
