The free version gives you the basics, but the premium version really shines with its advanced features.

However, it still cannot compete with Grammarly as the best writing tool in this category. In our eyes, Grammarly is worth the more expensive price.

LanguageTool is a reliable and efficient writing assistant that supports multiple languages. Its advanced grammar and style checks make it a valuable tool for writers and professionals. While the premium version offers excellent features, the free version is somewhat limited. Overall, LanguageTool is a solid choice for anyone looking to improve their writing.

Compared to Grammarly, LanguageTool holds its own, especially if you need to write in multiple languages. When it comes to writing in different languages, LanguageTool is the way to go. But if you’re only writing in English, Grammarly still delivers better results.
