LanguageTool checks grammar and style across more than 25 languages, which is broader coverage than most competitors. The core is open source and can be self-hosted, which matters for anyone who cannot send text to a third party. It integrates with browsers, office suites, and editors. The free tier covers basic checking with a length limit.
Who it is for
