Language Tool Review 2026 - Features, Pricing & Deals

LanguageTool is an AI-powered writing assistant that helps users improve their writing across more than 45 languages and dialects. It spots and corrects common writing issues like grammar mistakes, spelling errors, and punctuation problems while offering style suggestions to enhance overall readability.

The tool integrates with popular platforms such as Google Docs, Microsoft Word, LibreOffice, and all major web browsers through extensions. It works on most websites including Gmail, Facebook, Twitter, and LinkedIn. Users see blue underlines for identified issues and can click to accept suggestions or double-click words to view synonyms. Its privacy-focused approach means your text isn't stored on their servers, making it a secure choice for sensitive content.

While the free version handles basic writing corrections, premium subscribers get access to advanced features like AI-powered paraphrasing, detailed style suggestions, personal dictionaries, and expanded character limits. The premium version starts at $4.99 monthly when billed yearly, with options available for both individual users and business teams.

Whether you're writing in English, German, French, or any of the other supported languages, the tool adapts to understand context and language-specific rules. It helps both native speakers polish their work and assists language learners in avoiding common mistakes.

LanguageTool stands out for its multilingual support, covering over 45 languages and dialects compared to Grammarly's focus on English. While both tools check grammar and spelling, LanguageTool offers more affordable premium plans and doesn't require registration to use basic features. Many users find LanguageTool's open-source nature appealing, allowing the community to contribute to its development. Grammarly might have more advanced style features, but LanguageTool excels for multilingual writers and those wanting a straightforward, privacy-focused tool.

Yes, LanguageTool takes privacy seriously. It doesn't store any of your text after checking it, and all data is sent through encrypted connections. The free browser extension can check text right on your computer without sending it to servers when possible. For longer texts that need server processing, the data isn't saved after the check is complete. This makes LanguageTool a good choice if you're concerned about keeping your writing private.

Yes, you can use LanguageTool offline with some limitations. The desktop version for Windows, macOS, and Linux offers offline checking for basic grammar and spelling issues. However, some advanced features that rely on server-side processing won't be available offline. The offline version supports fewer languages than the online tool. If you need full functionality while traveling or in areas with limited internet, you should download the desktop application before you go.

LanguageTool works with all major browsers including Chrome, Firefox, Safari, Edge, and Opera through extensions. It integrates directly with Google Docs, Microsoft Word, and LibreOffice. You can also use it on most websites including Gmail, Facebook, Twitter, LinkedIn, and other social media platforms where you write text. The tool is compatible with both Windows and Mac operating systems, making it accessible no matter what device you use for writing.

The free version of LanguageTool works well for basic writing needs. It catches common spelling, grammar, and punctuation errors in texts up to 10,000-20,000 characters. However, the premium version offers more thorough checking with AI-powered paraphrasing, style suggestions, higher character limits (40,000-100,000), and detection of incorrect names or numbers. Most casual writers will find the free version sufficient, but if you write professionally or need advanced features like personal dictionaries and tone checkers, the premium version at $4.99/month (annual plan) provides better value.
