LanguageTool
Multilingual grammar checking with genuinely strong non-English support
At a glance
Multilingual writers and teams needing non-English grammar support
Our take
LanguageTool started as an open-source project and still carries that ethos — genuinely strong multilingual support that puts English-only competitors to shame if you write in more than one language. We think it’s the best pick for multilingual teams and non-English writers specifically, since grammar rules are built per-language rather than translated afterthoughts. Its English-only grammar checking is solid but slightly behind Grammarly’s polish and suggestion quality. Privacy-conscious users also appreciate that it can be self-hosted, which almost no competitor offers.
