How the Grammar Checker Works
When you run a check, your text is sent to LanguageTool. Issues come back underlined directly in your text, editor-style, with a one-tap fix for each — no separate report to cross-reference against your draft.
Inline Grammar & Spelling Suggestions
Each issue is tagged as spelling, grammar or style, with up to five suggested replacements you can accept or dismiss.
