About Grammarly

Grammarly is the AI writing assistant that checks grammar, spelling, clarity, tone, and style everywhere you type — email, docs, messages, social posts, and the web. It has been the standard for writing improvement for over a decade.

Its generative AI can draft, rewrite, and adjust tone, turning a terse email into a polished message or a casual note into a professional one. The browser extension works across virtually every site.

For anyone who writes in English — which is everyone doing business online — Grammarly is the quiet upgrade that makes every message better.
