About LanguageTool
What is LanguageTool (2026 update)
LanguageTool is a grammar, spelling, and style checker that reviews writing in more than 30 languages, including English, Spanish, French, German, and others, and can rephrase sentences to be shorter, more formal, or more fluent. It works through a website, browser extension, and integrations with word processors, making it a direct competitor to tools like Grammarly for people who write in multiple languages.
What is new in 2026
The most notable 2026 change is that LanguageTool moved its browser extension to a Premium-only feature, so free users now access the Grammar Checker and Paraphrasing Tool through the website rather than the browser add-on. Premium itself has continued to emphasize multilingual correction across more than 20 languages plus translation support between 10-plus languages, alongside unlimited AI-powered sentence paraphrasing, custom style guides, and writing statistics that show error trends and usage metrics over time. The free tier’s core checks remain available with a 20,000-character check limit and basic grammar suggestions, while Premium raises that text field capacity to 150,000 characters and layers in more than 20,000 additional checks across seven supported languages. This split pushes users who want deeper multilingual accuracy, longer documents, or in-line browser checking toward the paid tier more clearly than in prior years.

Who should use it
LanguageTool suits writers, students, and professionals who work across multiple languages and want grammar and style checking beyond English alone, since its multilingual coverage is broader than many English-first competitors. The AI paraphrasing and custom style guide tools on Premium make it useful for anyone editing long documents or maintaining consistent tone across a team. Casual users who only need occasional English spell-checking and do not mind losing browser-extension access on the free tier can likely stick with the free plan. Small teams that need consistent grammar and tone across shared documents may find the Team plan’s per-user pricing more practical than buying individual Premium seats separately.
Limitations and alternatives
Moving the browser extension behind Premium is a real downgrade for free users who relied on in-line checking outside the website, so evaluate that change carefully if browser-based checking matters to your workflow. Monthly Premium pricing at $19.90 is expensive compared to the annual rate of $4.99/month, so paying month-to-month is a poor value unless you only need short-term access. Alternatives include Grammarly for English-first writing with a larger AI assistant feature set, ProWritingAid for deeper style analysis aimed at long-form authors, and QuillBot for a paraphrasing-first tool at a lower entry price. Writers who only ever work in English and rarely need paraphrasing may not see enough added value in Premium to justify the upgrade.
