What is Grammarly?

Grammarly has evolved from a simple grammar checker into a comprehensive AI writing assistant. In 2026, Grammarly GrammarlyGO — its generative AI feature — can draft emails, rewrite sentences for tone and clarity, and even generate full documents. But Grammarly's core strength remains what it's always been: making sure everything you write is error-free, clear, and appropriate for your audience.
