While we covered many factors. we are still missing one of the most important parts that can fully determine which grammar application can be the one for you!

The Grammarly Free version lets you access their basic tools but still gives you a high-quality result.

But if you want to use all of their features, you have Grammarly premium plans:

This app also offers a free version that covers the most basic writing issues

The main difference is that it won’t show you all of them unless you access LanguageTool Premium.

LanguageTool offers four payment intervals for its premium plans:

Which Should You Choose?

LanguageTool and Grammarly are both effective tools for improving the quality of your writing.

Each offers a variety of features to help you craft clear and error-free content, but they differ in cost, integrations, and AI-generated suggestions.

Grammarly is an excellent choice for users who need advanced features like AI-powered spelling and grammar checking. It also offers a wide range of integrations to ensure that your writing is error-free wherever you go online. 

However, its premium subscription can be expensive for some users.

LanguageTool is a great tool for basic users who don’t need very advanced features or browser extensions. It provides reliable grammar checking without any additional cost.

However, it lacks the AI-generated suggestions and integrations offered by Grammarly, limiting its usability to basic applications.

So, in our opinion, if you are looking for a free version, we would suggest Grammarly since they have better tools available and allow you to personalize it. 

We have been using its premium version for years to help college students with their essays and classes and never had a problem with it. We highly recommend its plagiarism checker.

So, if you want to pay for their plans, it’s also worth the shot.

But if you want to invest less in an app that can adapt to multiple types of websites and formats, then LanguageTool is a great choice.
