Grammarly vs Writer
A side-by-side breakdown to help you pick the right tool for your workflow.
Grammarly
Catch grammar and clarity issues as you write, then let built-in AI agents draft, rewrite, and complete tasks across your apps. Grammarly's parent company rebranded to Superhuman in October 2025.
Writer
Draft on-brand marketing and business content while enforcing company style and compliance rules automatically, built for large organizations.
Bottom Line
Last reviewed: August 2026
Grammarly and Writer both sit in Writing, but they're built around different use cases within it. Grammarly runs on a freemium model while Writer runs on a paid-only plan, which alone may settle it if budget or a free tier is a hard requirement. Grammarly carries the higher rating (4.7 vs 4.5), but a gap that size rarely overrides a real workflow fit on its own.
Choose Grammarly if…
Best for catching grammar and clarity issues in real time as you write anywhere online, and its edge is built-in AI agents now draft and rewrite across your apps, not just proofread. The baseline writing check most people should already have running.
Choose Writer if…
Best for enterprises that need AI-generated content to actually sound like their brand, not median internet writing, and its edge is trained on your organization's own approved content and terminology, then enforces it across every output. A real reduction in editing cycles once trained, the enterprise pricing rules out solo creators and small teams.
