Grammarly checks and improves writing wherever you type — browsers, email, docs, chat — catching grammar and spelling on the free tier and offering full rewrites for tone, clarity and length on paid plans. Team plans add style guides and brand voice so everyone sounds like the company.
It suits anyone whose output is judged partly on writing, from support replies to marketing copy. General-purpose AI chatbots can rewrite text too; Grammarly’s edge is living in the flow of typing.
