What is Grammarly?
Grammarly is the most widely used AI writing assistant, with 30+ million daily active users. While it started as a grammar checker, Grammarly has evolved into a comprehensive writing quality platform with AI-powered style suggestions, tone detection, clarity improvements, and enterprise brand guidelines.
Grammarly's key advantage is its ubiquity — it works in your browser, desktop apps, Microsoft Office, Google Docs, email clients, and even your phone keyboard. No matter where you write, Grammarly is there.
The tone detector analyzes your writing and tells you how it sounds (confident, friendly, formal, etc.), while the clarity suggestions help you write more concisely. For teams, Grammarly Business adds brand tone guidelines and style guides — ensuring consistent communication across the organization.
