Frequently asked questions
Is this grammar checker free?
Yes — it runs on the open-source LanguageTool engine. The bundled backend uses the free public API; self-host LanguageTool for unlimited, fully private checking.
What languages are supported?
English (US/UK), Spanish, French, German, Portuguese, and more, selectable before checking.
Is my text private?
Text is sent to your configured backend. If you self-host LanguageTool, nothing leaves your own infrastructure.
