Grammarly
The trusted assistant that checks clarity, tone and correctness everywhere you type.
Grammarly is the writing assistant most teams already know, and its strength is breadth: real time grammar, spelling, clarity and tone suggestions in almost every app you write in, from email to docs to chat. A generative assistant now sits alongside the checker for drafting, rewriting and replies, and the enterprise tier adds the security, SSO and admin controls large companies ask for. The tradeoff is scope. Grammarly is built to improve writing you are already doing, not to generate long form marketing articles or score content for SEO, so a content team will still want a dedicated writer beside it. For everyday business writing, though, few tools are as quietly useful.

In its favour
Held against it
Clarity and ease lead, long form and SEO are not the point.
Grammarly scores high on ease and everyday output, the traits that made it ubiquitous. Workflow and SEO sit lower because it improves writing rather than generating campaigns or optimizing for search.
Scored against the same five weighted criteria we use across AI writing. See the rubric →
a team that writes constantly across email, docs and chat and wants every message clear, correct and on tone.
a marketing team that needs long form articles, brand voice at scale or built in SEO scoring from one tool.
