LanguageTool is an AI-powered multilingual spelling, style, and grammar checker that assists with correcting or paraphrasing texts. It offers a “distraction-free writing experience,” a personal dictionary, quality scoring for evaluating style and grammar, along with storage of texts. A special feature called “Picky Mode” provides advanced punctuation, style, and typography suggestions.
LanguageTool works across devices and platforms. Its browser add-on can provide tips to improve your text while typing an email, a blog post, or a tweet. It can automatically detect the language you’re using and provide suggestions. Also, LanguageTool can integrate with popular office programs, such as MS Word and Google Docs, helping you deliver error-free results every single time. Furthermore, there are mobile apps for iOS and Android.
LanguageTool goes beyond spell-checking to also check for grammar errors, punctuation, and even offers advice on forming complex sentences thanks to its AI-based paraphraser. Plus, it can correct casing errors, such as when writing capitalized names, months, places, or national identities — as well as improve writing style by detecting overused phrases, foreign terms, redundant words, and improper word choices.
The tool supports more than 30 languages and dialects — including English, Spanish, German, French, Dutch, and Portuguese, while offering language variations of English like the US, UK, Canada, Australia, New Zealand, and South Africa.
LanguageTool is available in two tiers: a free version that corrects spelling, simple punctuation, and some style mistakes; and a Premium version that goes beyond that to help produce the best possible text.
The tool is especially useful for academic texts like term papers, theses, and other scholarly works, with a discount available for students. It is used by numerous organizations, such as BMW Group, European Union, and Deutsche Presse-Agentur.
