LanguageTool vs. Grammarly

LanguageTool vs. Grammarly

Grammarly is one of the most used grammar tools. From spelling to clarity, it has all we need. Another writing assistant is LanguageTool.

It’s not as popular, but it sure is an excellent program. How would both stand in a battle? This article looks at both and covers LanguageTool vs. Grammarly.

The main difference

One of the advantages LanguageTools has is that it supports over 20 languages. It underlines wrong words and phrases in either red, yellow, or purple to help you understand the mistakes.

  • Red suggests spelling mistakes.
  • Yellow suggests agreement errors.
  • Purple shows style issues.

On the contrary, Grammarly only supports English. You can select American, British, Canadian, and Australian English.

Even though it comes with British and Australian English options, the tool mainly suggests fixes according to British English (personal experience). Like LanguageTool, it underlines text and phrases as you go.

  • The Red color indicates spelling, grammar, and punctuation mistakes.
  • Blue suggests clarity issues.
  • Purple is for tone or politeness issues.
  • The green color underline suggests that the content can be improved.

Like LanguageTool, Grammarly offers basic grammar, tone, and spell-checking features in its free plan, while you get a wide range of services in the paid plans.


LanguageTool is available on:

  • Google Chrome
  • Firefox
  • Microsoft Edge
  • Safari
  • Opera
  • Google Docs
  • Word
  • LibreOffice
  • OpenOffice
  • Windows PC
  • macOS
  • iOS

It is not yet available for Android. Grammarly, in comparison, supports mobile and desktop devices. Like LanguageTool, you find Grammarly extension for Microsoft Word and major browsers. The app is in the beta version on Google Docs.

Pricing and plans

LanguageTool and Grammarly Pricing

Starting with LanguageTool, The free plan is called: For Beginners, which offers to check grammar, spelling, and punctuation mistakes.

The first premium plan is: For Individual Users. It costs:

  • $19 per month on a month-to-month plan
  • $39 ($13/mo) on a quarterly plan
  • $59 ($4.92/mo) on a one-year plan
  • $99 ($4.13/mo) on a two-year plan

You get advanced suggestions, enhanced grammar checking, and an extended character limit per document.

The final plan, which offers the same features as “For Individual,” is for teams. It is only available on a yearly plan charging $106.2 per year for two users. You can add up to 20 users: the more users, the savings.

Grammarly also comes in two premium plans. The free plan checks for grammar, spelling, and punctuation errors, while the Premium plan, along with free plan options, supports:

  • Clarity: Helps in clarifying the writing.
  • Plagiarism check: Checks the text on over 16 billion pages. I also did many tests to find out that Grammarly is 86% accurate.
  • Engagement: Helps in making writing more effective.
  • Fluency: Makes text more fluent.
  • Delivery: Helps you deliver the correct text.

Like LanguageTool, you can subscribe to a monthly, quarterly, and annual plan. The monthly plan costs $30, the quarterly costs $20/month, and the yearly plan costs $12/month.

The business plan is a bit more expensive than the premium plan and offers team-focused tools such as brand tone detection, analytics dashboard, single sign-on, etc.

Which one is better?

Grammarly is one of those tools that do pretty much everything for you. That is why it is more expensive than other programs. The tool is more powerful and confident.

It mainly suggests one word, which is the fix for the error. Tools like Linguix and LanguageTool show a few suggestions, and you must pick one.

So, if your English is already good or you are a native writer, I believe LanguageTool may save money. If you want to rely upon a writing assistant a lot, then Grammarly is the right tool.
