What it really isGrammarly — AI-powered writing assistant for grammar, clarity, style, and tone across all platforms.
Our takeGrammarly is a full cross-platform AI writing layer covering desktop apps, MS Word, Outlook, iOS, Android, and the web.
The 'Premium' plan was rebranded to 'Pro' in late 2024 as part of a restructure that merged the old Business plan into a single Pro tier ($12/seat/mo annual). Enterprise with custom pricing covers 150+ seat teams needing SSO, SCIM, and BYOK encryption.
Why we rate itGrammarly has earned its dominant position through years of accuracy improvements and the widest platform footprint in the category.
The 2024 Pro restructure simplified pricing without sacrificing features, and the free tier is genuinely usable for light writers.
The catchMonthly billing ($30/seat) is 2.5× the annual rate, making short-term commitment expensive.
The free tier is noticeably limited, which can feel like a persistent upsell. Non-English writing support is weaker than competitors.

Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Fast: browser extension installs in under a minute and corrections appear inline immediately; no configuration needed to get value.
  2. Scale breakpoint
    Pro plan caps at 149 seats — teams at 150+ users must move to custom-priced Enterprise, which requires a sales conversation.
  3. Walled garden
    Moderate: all text is processed in Grammarly's cloud (privacy trade-off); no offline mode; however, switching is low-cost since Grammarly layers on top of existing tools and holds no user documents.
Still a fit?
If none of these block you, start on the free plan.
