Overview
Grammarly is an AI writing assistant used for grammar correction, rewriting, tone adjustment, fluency, citation support, plagiarism detection, AI detection, and writing feedback across common work surfaces. It is available through browser extensions, desktop apps, mobile keyboards, web editors, and integrations such as Google Docs and Microsoft Office.
The product has moved beyond basic spell checking. Grammarly's current plans page positions Pro as the paid plan for eligible individuals and teams, while Enterprise is positioned by Grammarly as available through Superhuman Go, with deeper security, controls, support, and organization-wide governance. That makes Grammarly useful for both individual writers and teams that need consistent writing quality across email, documents, support replies, sales messages, and internal communications.
As of April 28, 2026, Grammarly's official pricing page lists Free at $0/month, Pro at $12 USD/member/month when billed annually or $30 USD/member/month when billed monthly, with a 7-day trial, and Enterprise via sales. It also compares AI prompt limits, with Free including 100 prompts per month, Pro including 2,000 prompts per member per month, and Enterprise including unlimited prompts per member per month. Buyers comparing AI writing tools should decide whether they need just writing correction or team-level style, brand, security, and analytics controls.
