What Is Grammarly AI?
Grammarly is the writing assistant used by 30+ million people, and it's evolved far beyond spell check. The AI now rewrites entire paragraphs for clarity, adjusts tone for different audiences, generates text from prompts, and catches nuanced issues like wordiness, passive voice, and inconsistent formality. It works everywhere you write — email, docs, Slack, social media, and more.
Who Is It For?
Everyone who writes in English for business. Grammarly is valuable whether you're a confident writer who wants a safety net or someone who struggles with tone and grammar. Particularly useful for non-native English speakers, customer-facing teams, and anyone sending important emails or proposals.
