Grammarly is the world's most popular AI writing assistant, used by over 30 million people to improve grammar, spelling, clarity, tone, and style across browsers, desktop apps, and mobile devices. Founded in 2009, Grammarly has evolved from a grammar checker into a comprehensive AI communication platform with generative AI capabilities, plagiarism detection, and enterprise-grade collaboration features. The company recently rebranded its parent entity to Superhuman Platform Inc. while maintaining the Grammarly product brand.

Grammarly pricing is straightforward: a free plan with basic corrections and 100 AI prompts/month, Pro at $12-$30/month depending on billing frequency (annual, quarterly, or monthly), and custom Enterprise pricing for organizations with 150+ users. Unlike most AI writing tools that focus on content generation, Grammarly specializes in improving and polishing existing writing, making it complementary to tools like Jasper, Copy.ai, and Writesonic.

This pricing guide covers all Grammarly plans, highlights the significant cost difference between monthly and annual billing, explains the AI prompt system, and compares Grammarly to alternatives like Wordtune, Rytr, and other writing assistants.

Hidden Costs to Budget For

Watch for 6 hidden costs
  • No refunds on any Pro plan -- you can cancel to stop the next billing cycle, but Grammarly will not refund your current period even if you cancel immediately after purchase
  • Monthly Pro billing costs 150% more than annual ($30/month vs $12/month annually) -- the headline $12/month price requires a full $144 upfront annual commitment
  • Quarterly billing is a middle ground at $20/month ($60 every 3 months) but still costs 67% more than annual pricing
  • No gift subscriptions, lifetime plans, or one-time purchase options available -- all plans require recurring subscriptions
  • AI generative prompts are capped at 100/month (Free) and 2,000/month (Pro) -- heavy users of Grammarly's AI writing assistance may hit these limits and cannot purchase additional prompts
  • Enterprise pricing is quote-based with no published prices, and typically requires minimum user counts and annual commitments that can be significantly more expensive per seat than self-serve plans
Tip

Ask your Grammarly sales rep about these costs upfront. Getting them in writing before signing can save you from surprise charges later.

Frequently Asked Questions

01 How much does Grammarly cost?

Grammarly offers a free plan with basic features and 100 AI prompts/month. Grammarly Pro costs $30/month (monthly billing), $20/month (quarterly at $60/3 months), or $12/month (annual at $144/year). Enterprise pricing is custom and quote-based. The annual plan saves 60% compared to monthly billing and is the most cost-effective option for individual users.

02 Is Grammarly free?

Yes, Grammarly offers a permanent free plan that includes basic grammar and spelling checks, tone detection, 100 AI prompts per month, and works across browsers, desktop apps, and mobile. The free plan is genuinely useful for basic writing correction but lacks advanced features like full-sentence rewrites, plagiarism detection, vocabulary suggestions, and the 2,000 AI prompts available on Pro.

03 What is Grammarly?

Grammarly is an AI-powered writing assistant that helps improve grammar, spelling, punctuation, clarity, tone, and style across virtually any platform. Founded in 2009 by Alex Shevchenko, Max Lytvyn, and Dmytro Lider, Grammarly works as a browser extension, desktop app, mobile keyboard, and integrates with tools like Google Docs, Microsoft Office, and email clients. With over 30 million users, Grammarly is one of the most widely used writing tools globally.

04 Grammarly vs Wordtune -- which is better?

Grammarly Pro starts at $12/month (annual) and focuses on comprehensive grammar, tone, and clarity improvements across all platforms. Wordtune starts at $6.99/month (annual) and specializes in sentence-level rewriting and paraphrasing. Grammarly is better for overall writing quality, plagiarism checking, and broad platform support. Wordtune is better for creative rephrasing and is cheaper. Many writers use both tools together.

05 Does Grammarly offer student discounts?

Grammarly does not offer a direct student discount for individual subscriptions. However, many universities and educational institutions provide Grammarly access through institutional licenses. Check with your school's IT department or writing center. Grammarly also adjusts pricing by region, so prices may be lower in certain countries.

06 What is the difference between Grammarly Free and Pro?

Grammarly Free includes basic grammar, spelling, and tone checks with 100 AI prompts/month. Grammarly Pro adds full-sentence rewrites, advanced tone suggestions, vocabulary improvements, clarity and conciseness edits, plagiarism detection, formatting suggestions, and 2,000 AI prompts/month. Pro is worth upgrading to for professional writing, academic work, or anyone who writes frequently.

07 Does Grammarly offer a free trial?

Grammarly does not offer a traditional free trial of Pro. Instead, it provides a permanent free plan that lets you use basic features indefinitely. This allows you to evaluate the interface and basic capabilities before upgrading. Some institutional plans may include a 7-day trial option. Note that Grammarly does not offer refunds, so the free plan is your best way to evaluate before committing.

08 Can I use Grammarly with Google Docs and Microsoft Word?

Yes, Grammarly works with Google Docs through its browser extension and with Microsoft Word through a dedicated plugin. It also works across Gmail, Outlook, Slack, LinkedIn, social media platforms, and virtually any text field in your browser. The desktop app provides native integration on both Windows and Mac. All platforms are supported on both Free and Pro plans.
