What Is Grammarly?
Grammarly is the most widely-used writing assistant, with 30+ million daily active users. The browser extension works across virtually every web-based writing tool — Gmail, Google Docs, LinkedIn, Slack, and more — making it the most accessible writing improvement tool. The free tier covers grammar and spelling corrections plus 100 AI prompts per month for rewriting, tone adjustment, and suggestions.
Grammarly Premium ($12/month) adds style suggestions, clarity improvements, engagement metrics, and plagiarism checking. Business plans add team features and brand voice customization. Unlike standalone AI writers like ChatGPT, Grammarly focuses on improving existing text rather than generating from scratch — positioning it as a complement to AI tools rather than a replacement.
