Grammarly AI is an advanced writing assistant developed by Grammarly. Originally known as a grammar-checking tool, it has evolved into a full AI-powered communication platform that helps users write clearly, correctly, and effectively across emails, documents, and online platforms.
Today, Grammarly combines traditional proofreading with generative AI features (often referred to as GrammarlyGO), transforming it into a comprehensive writing assistant.
