Grammarly’s public plans page (read 29 Sep 2026) lists three plans: Free, Pro and Enterprise. In the US, Pro is $30 a month billed monthly, $60 per three months, or $144 a year ($12 a month), per Grammarly’s support page; the Dutch plans page shows EUR 12 with a 7-day free trial (a regional price, with no billing period beside it, most likely the annual-equivalent). Free gets 100 AI prompts a month, Pro 2,000, Enterprise unlimited. The old Premium plan has been folded into Pro for people who bought it from Grammarly’s site, and Pro also covers teams of up to 149 members; Premium and Business are no longer on the plans page, but Premium stays available through the App Store and Google Play, and Grammarly says Pro is not available to existing Business customers.

Grammarly’s support page gives the US prices by billing period: $30 a member monthly, $60 a member per three months and $144 a member a year, and says regional prices in euros, pounds and rupees are shown at checkout. The Dutch page did not state a period beside EUR 12; because $144 a year is $12 a month, EUR 12 is most likely the annual-equivalent, but we could not confirm it, so check the period at checkout. The page has no separate team tier below Enterprise, and Pro supports up to 149 members; style guides and brand tones are limited to 1 in the comparison table’s middle column and unlimited on Enterprise.
Who it suits, who should skip
- Free covers spelling, grammar and tone detection for most everyday writing.
- Pro suits people who want rewrites, plagiarism and AI-text checks, and a larger prompt allowance.
- Skip if you want a general assistant: prompts are capped and the product is a writing layer. Compare ChatGPT and Claude, or the paraphrasing tool QuillBot.
- Skip the AI-text detection as evidence: detectors are not proof of authorship, and we have not assessed this one.
What this page cannot tell you
Suggestion accuracy and how the extension behaves across sites are not on a plans page, and we have not assessed them. Testimonials on the page are the vendor’s own.
