Launch Grammarly and start using it right away
Grammarly is a writing assistant that checks spelling, grammar and tone, and suggests clearer ways to phrase a sentence. It works in the browser, on desktop and mobile, and inside Microsoft Office and Google Docs. You can also use its AI chat to draft or rework text.
The Free plan covers basic spelling and grammar checks and a monthly allowance of AI prompts. Pro adds full-sentence rewrites, tone adjustment, plagiarism detection, AI-content detection and a larger prompt allowance, and offers a seven-day free trial. The product also includes agent-style tools for tasks such as building a resume, finding citations and getting feedback on how a draft may land with readers.
Grammarly is now part of Superhuman. Enterprise plans are sold through Superhuman Go, and the product continues under the Grammarly name.
