Write confidently in English, Spanish, French, German, Dutch, Portuguese, and many more, including regional dialects.
Catches grammar mistakes, punctuation errors, word choice issues, and style problems that simple spell checkers miss.

Add your own words, names, and terms so LanguageTool learns your unique vocabulary and stops flagging them as errors.
Track your progress over time with insights on errors made, suggestions applied, and languages used.
If you fit one of these, LanguageTool is probably built for you.
