We believe that anyone can write beautifully and professionally

Our mission at LanguageTool is to unleash the professional writing skills in every one of our users. For this, we are going far beyond grammar and spelling, with an AI-based technology that analyzes the style, tonality and typography of your text and instantly generates context-aware suggestions.

A team of linguistic professionals and machine learning experts from across the globe is enhancing the product on a daily basis to make the best multilingual text corrector you can find on the web.

It all started in 2003 as an open-source project that attracted many contributors, fans and followers, and over time turned into a service that helps millions of users every day to improve their writing.
