How Does Grammar Checker Pro Work?
Ghostools Grammar Checker Pro scans English text for common grammar patterns, frequent spelling mistakes, punctuation problems, repeated words, and readability concerns. Review each suggestion before applying it to preserve your intended meaning.
Your text is processed directly in your browser by this tool. No grammar API or account is required. Because it uses rule-based checks rather than a full language model, it cannot reliably understand every context, dialect, or complex sentence.
