Grammarly review

Grammarly earns its place for teams whose writers draft in many places: email, Google Docs, the CMS and social schedulers. The browser and desktop apps check grammar and tone wherever text is typed, and Pro adds full-sentence rewrites, tone adjustment, fluency help, plagiarism and AI text detection, and 2,000 AI prompts per member each month for generating or reworking copy. For teams, Pro includes one style guide and one brand tone, so common terms and voice rules are applied as people write. At $12 per member a month on annual billing it is the cheapest per-seat paid plan here. It is not a replacement for a drafting platform: long-form generation, research and campaign workflows are lighter than in ChatGPT, Claude or Jasper, and unlimited style guides and brand tones sit on the Enterprise plan sold through Superhuman Go.

Who it is for

Teams that want cleaner, on-brand copy in every app rather than a separate drafting tool.
