Which Types of Mistakes Does LanguageTool Correct?


Spell Checker

Yes, LanguageTool will correct common typos and spelling errors, like improperly using affect and effect or break and brake.

But going beyond just an average spell checker, LanguageTool can also detect errors like an incorrectly written date:

Example of LanguageTool detecting a wrong date "The date May 9th 2022 is not a Sunday, but a Monday."
Incorrectly written dates can cause big problems. Luckily, LanguageTool will tell you when you’ve written a date wrong.

Grammar Checker

Proper grammar can be challenging, regardless of which language you’re writing in. LanguageTool’s grammar checker can correct a multitude of mistakes, like improperly using less and fewer or if I was and if I were, just to name a few.

With LanguageTool as your writing assistant, you’ll never have to worry about incorrect grammar.

Style Checker

LanguageTool’s editor enhances your writing by fixing spelling and grammar errors, but also by making suggestions to improve your writing style. The recommendations help your writing become clear and more effective. For example, it can detect a sentence written in the passive voice and will recommend you restructure it to the active voice instead.

Additionally, it can identify sentences that are too long or phrases that are too wordy. As if that weren’t enough, a quick double-click can give you synonyms of any word you type, helping you convey your message more accurately.

To help you avoid wordiness, LanguageTool will recommend replacing “in a…manner” phrases with their adverb equivalent.
