What is Grammarly?
Grammarly is a smart writing assistant powered by artificial intelligence that helps you write more clearly and confidently in English. Whether you’re composing an email, blog post, essay or social media message, it checks your spelling, grammar and punctuation and even suggests better word choices and adjusts your tone so your message comes across just right.
Behind the scenes, Grammarly uses advanced machine-learning models alongside linguistic rules to analyze how you write. It spots mistakes that basic spell-checkers miss and offers suggestions for clarity, style and readability. You can use Grammarly as a standalone app, browser extension, Microsoft Office add-on, or mobile keyboard basically wherever you type.
Over the years Grammarly has evolved from a simple grammar corrector into a full writing partner. It now includes features like plagiarism detection, tone detection, generative AI tools that help you brainstorm and rephrase, and new smart “AI agents” that collaborate with your writing process.
