Examples
Spelling

Grammar
'She don't know' is flagged. The correction is 'She doesn't know' with an explanation of subject-verb agreement.
Style
Phrases like 'due to the fact that' are flagged as wordy. The suggestion is to replace with 'because'.
Punctuation
A missing comma before a coordinating conjunction in a compound sentence is highlighted with an explanation.
Common Mistakes to Avoid
- !Ignoring style suggestions - they often catch passive voice and filler phrases that weaken writing
- !Running the check once and not re-checking after making edits, as fixes can introduce new issues
- !Treating every suggestion as correct - the checker can occasionally flag proper nouns or technical terms
Limitations
- –The tool checks grammar and style but cannot assess whether the argument or logic of your writing is sound
- –Highly specialised technical jargon may be flagged as errors even when used correctly
- –Context-dependent errors (such as using 'affect' vs 'effect' correctly in a sentence) can sometimes be missed
Privacy
Text is sent to the LanguageTool API for analysis and is not stored after the check completes. Avoid pasting highly confidential content such as passwords, legal documents under NDA, or private personal information.
