What is LanguageTool?
LanguageTool is a writing assistant for students, professional writers, businesses, and multilingual users who want accurate grammar, spelling, punctuation, and style checking, especially across languages other than English.
It checks text in more than thirty languages and is widely regarded as one of the strongest options for multilingual accuracy, making it a popular alternative to English-centric tools.
The free version catches spelling and basic punctuation and some style mistakes, while Premium expands detection, adds advanced style suggestions for word choice and redundancy, and includes an AI-powered paraphrasing feature that can rephrase sentences to be more formal, fluent, simple, or concise.
It integrates broadly, working in major browsers, email clients, and office software like Word and Google Docs, so checking happens wherever you write, and it offers statistics to track writing improvement over time. LanguageTool suits anyone who writes in multiple languages or wants a privacy-respecting, well-integrated checker.

It uses a freemium model with a functional free tier and a Premium plan that unlocks advanced checks and unlimited paraphrasing. Pricing changes often, so check the official site for current plans.
