About Grammarly
Grammarly is an AI writing assistant that helps you refine grammar, structure, and clarity. The official homepage lists two core capabilities: Proofreading and the AI Detector agent — the first refines grammar, structure, and clarity, while the second identifies AI-generated text and points out the areas that need editing. The Pro plan adds one-click full-sentence rewriting, writing tone adjustment, personalized suggestions, plagiarism and AI-generated text detection, and prompt-based AI text generation. The official homepage says Grammarly is used by 50,000 organizations and 40 million people.
