Grammarly pricing explained
A genuinely useful free plan, a single Pro tier that now scales to 149 seats, and custom Enterprise, where billing term and AI usage decide your cost.
Grammarly keeps its pricing unusually simple. There is a permanent free plan, a single paid Pro tier that absorbed the old Premium and Business plans and now scales to 149 seats, and a custom quoted Enterprise plan for larger organizations. Pro is $12 a seat a month billed annually, or $30 monthly, and includes 2,000 AI prompts per member each month. The levers are which plan you need, your billing term and how much generative AI you use. Below is every plan as of June 2026, then what actually moves your bill. Check the vendor for current pricing.
