How it works
The tool is popular with non-native English speakers and professional writers who want to check whether a phrase sounds natural. You can search for a sentence pattern, compare alternatives, and get grammar suggestions.
Ludwig is a research tool for language, not a grammar checker or a writer. It shines when you know roughly what you want to say but are unsure of the exact wording, and it is most useful as a companion to a full editor.
