Instead of LanguageTool
LanguageTool alternatives
LanguageTool combines grammar, spelling, punctuation, casing, style, paraphrasing, and statistics, with tone detection and support for 31 languages. Its free version covers spelling, simple punctuation, and some style mistakes; Premium raises the text-field limit to 150,000 characters and offers paraphrasing modes. Browser extensions, desktop apps for Windows and macOS, an iOS app, and integrations with common word processors and email services suit varied writing routines. Teams can share style guides and dictionaries, and text entered through the browser add-on is usually not saved.

A switch may make sense if the free tier’s checks are too narrow, or if you need a different platform, workflow, or specialized tool. LanguageTool’s plans have no prices specified, and its stated apps are for Windows, macOS, and iOS. Compare alternatives by language coverage, writing features, device support, and cost. Academic writers may want citation or plagiarism tools; product teams may value an API or self-hosting; writers who prioritize local processing may prefer a checker that runs on their device. Each option below trades LanguageTool’s broad language support for a different focus or setup.
