What is Grammarly?

Grammarly predates the AI boom but has quietly become one of the most widely used writing assistants with AI baked in. The core grammar and tone suggestions are unmatched in speed and reliability, and the newer generative features (rewrite, expand, reply) compete with ChatGPT for quick email drafts. Works inline everywhere — Gmail, Docs, Slack, LinkedIn.
