Grammarly Pricing in 2026: Free vs Pro, Enterprise and What You Really Pay

Grammarly Pro costs $12 per member a month when billed annually, which is $144 for the year. The same seat is $60 per quarter or $30 month to month, so the monthly plan costs 2.5 times the annual one over twelve months. Free stays at $0 with 100 AI prompts a month, and Enterprise is a quote. Prices read on Grammarly's own pages on October 17, 2026.

The annual Pro plan is the only sensible paid option for anyone who writes every week. Quarterly billing is a $240-a-year compromise for a semester or a project, and monthly billing at $360 a year is for a single deadline, if that. The rest of this page covers what each tier includes, where the limits bite, what Grammarly charges a team of five, how the Superhuman bundle changes the math, and how the price stacks up against QuillBot and Wordtune.

Toolradar data: the best AI writing tools ranking we publish evaluated 139 tools, updated October 2026, and Grammarly is the one most buyers in that set already have installed. The product record lives on Grammarly's Toolradar page, and the category view is our best AI writing tools comparison.

Free is a grammar checker, not a writing assistant

The free plan catches spelling, grammar and punctuation mistakes, shows the tone of what you wrote, and gives you 100 generative AI prompts a month. That covers a student proofreading essays or anyone who wants a second look at emails, and it runs in the browser extension, the desktop app and the mobile keyboard at no charge. For most casual writers the free tier is the right answer, and our best free AI grammar checkers guide puts it next to the free tiers of Wordtune, LanguageTool and ProWritingAid.

What free does not do is rewrite. Full-sentence rewrites, tone adjustment, fluency suggestions for non-native English writers, plagiarism detection and AI-generated text detection all sit behind Pro. Grammarly's plans page is explicit that free users "write without spelling and grammar mistakes" while Pro users "rewrite full sentences with a click". If you upgrade, you are paying for the rewrites and the detection, not for better grammar checks.

The 100-prompt cap is the other ceiling. Each time you ask Grammarly to draft, shorten or reply, it counts one prompt, so 100 a month is about three a day. A person who uses Grammarly as a drafting tool rather than a proofreader will hit it in the first week.

Pro is one price paid three ways, and the billing cycle matters more than the plan

Grammarly's support page lists three ways to pay for Pro: month to month, $60 per member every three months, or the annual charge it describes as an average of twelve dollars a month. Those three prices buy the same product. The only variable is how long you commit, and the gap is large: a year on monthly billing is $360, a year on quarterly billing is $240, a year paid upfront is $144.

Pro includes 2,000 generative AI prompts per member each month, twenty times the free allowance, plus plagiarism checks, AI detection, sentence rewrites, tone changes and fluency suggestions. It also carries the team features that used to be a separate Business plan: one style guide, one brand tone, up to two user groups, knowledge share and snippets, team and individual analytics, and priority support. Grammarly's support page says Pro "replaces the Grammarly Business plan" and accepts 1 to 149 seats.

Three things buyers miss. First, the old Grammarly Premium plan is being folded into Pro: Grammarly says Premium subscribers who bought on its website are upgraded to Pro at no extra cost, while App Store and Google Play subscribers keep Premium, which had 1,000 AI prompts a month rather than 2,000. Second, the default currency is the US dollar, with regional pricing in euros, pounds and rupees shown at checkout, so a browser in Europe sees a different figure. Third, Grammarly Plus is a cheaper region-specific plan sold in select countries with the same core features and lower support priority, and it is not available in the US.

Extra seats are billed at the same per-member rates, prorated to the days left in the current period. There is no family plan: Grammarly's answer to that question is to add relatives as members on a Pro subscription at the full per-member price.

What a team pays

Grammarly bills Pro per member, so the team cost is a multiplication with no volume discount until Enterprise. All figures assume annual billing at the standard per-member rate.

A ten-person marketing team on annual Pro pays $1,440 a year and gets one shared style guide, one brand tone and two user groups. That is enough for one brand voice, not for an agency running six client voices, which is the point where Enterprise and its unlimited style guides start to make sense. Grammarly publishes no Enterprise price, so the cost of that step is a sales conversation.

The 149-seat cap on Pro is a hard line. A company at 150 people cannot buy Pro at the list price and has to take the quote. Below that line, the admin tools (roles and permissions, a feature management hub, usage analytics) are included in the seat, so a small team gets the governance features without an Enterprise contract.

The Superhuman bundle changes the price of Pro for new buyers

Grammarly's parent company now sells a suite called Superhuman that bundles Grammarly, Superhuman Mail, Superhuman Docs (the product formerly called Coda) and Superhuman Go, an AI agent layer, under one subscription. Grammarly's own announcement of the suite lists Superhuman Pro at the same per-member rate as annual Grammarly Pro, billed annually, or $15 billed monthly, and Superhuman Business at $33 per member a month billed annually or $40 billed monthly, with Enterprise on a custom quote.

The detail that matters: Grammarly says the annual Superhuman Pro plan includes Grammarly Pro access, while monthly Superhuman subscribers can add Grammarly Pro as a paid add-on. So a new buyer who commits annually can get Grammarly Pro plus the email client and the docs tool for the same monthly rate that Grammarly Pro alone costs. An existing Grammarly subscriber does not get the suite automatically; Grammarly states that current subscriptions and billing amounts stay the same and the suite is not switched on for them.

Two cautions before you buy the bundle for the discount. Superhuman Mail and Docs are products you have to adopt, and a team already on Gmail and Google Docs gains nothing by paying for a second email client it will not open. And the bundle's prices came from Grammarly's announcement rather than from a pricing table with a seat cap, so confirm the seat rules at checkout.

Trial, refunds and cancellation: the fine print

Grammarly says it periodically offers free trials of Pro to individuals and teams, and its billing help describes a seven-day free trial of a paid plan with no charge before the trial ends. A small pending charge can appear during the trial to validate the card, and it drops off if you cancel. The trial is not permanent: when it is not running, the plans page shows no trial button and you pay from day one.

Refunds are issued only if required by law. That sentence is Grammarly's entire refund policy for direct purchases, and it means a monthly plan is the only way to limit a mistake to $30. App Store purchases go through Apple's refund process instead. The one automatic exception: if you buy a team plan with the email address of an existing individual subscription, Grammarly refunds the individual plan on a prorated basis within about ten business days.

Subscriptions renew for the same duration as the original period unless you cancel before it ends, so an annual plan silently renews for another full year at the annual price. Canceling stops the renewal and keeps paid features until the end of the period you already paid for. Canceling a free trial is different: the account converts to free immediately, with no charge.

Grammarly vs QuillBot vs Wordtune on price

Grammarly is not the cheapest writing assistant, and for a buyer who mainly wants paraphrasing it is not the best value either. The prices below were read on each vendor's own pages in October 2026.

QuillBot Premium at $99.95 a year is $44 cheaper than annual Grammarly Pro, and its quarterly plan is $39.95 every three months against Grammarly's $60. Wordtune Unlimited on annual billing is $83.88 a year, and its Advanced tier at $4.89 a month billed annually caps you at 30 rewrites a day. Grammarly wins when the paid feature you need is plagiarism or AI detection, or a shared style guide for a team; neither Wordtune tier offers those, and QuillBot sells them as separate tools. For paraphrasing alone, the best AI humanizers and best AI detectors guides cover the tools that specialize in it.

A general assistant is the other comparison buyers make. ChatGPT Plus costs more per month than annual Grammarly Pro and does far more, but it does not sit inside Gmail, Word and Slack correcting as you type. Our ChatGPT pricing breakdown has those tiers, and how to write AI prompts covers getting a chatbot to edit the way Grammarly does. For a stack of writing tools with free tiers, start with best free AI writing tools and best free AI email writers.

Who should pay for Grammarly Pro

Pay for annual Pro if you write in English for a living and English is your second language: fluency suggestions and sentence rewrites are the two features that free users ask for most, and the annual price is less than a single hour of a human editor. Pay for it if you run a small team that needs one brand tone enforced across support, sales and marketing, because the style guide ships in the Pro seat with no Business upsell.

Skip it if you proofread occasionally and never generate text: the free plan already fixes the errors most people make. Skip it if paraphrasing is the main job, where QuillBot is cheaper, and skip it at 150 seats or more, where the Enterprise quote is the only door. Students writing essays will find the free tier plus the tools in our AI for writing essays guide covers most assignments, and a business deciding on its wider stack should read best AI tools for business first.

FAQ

How much does Grammarly cost in 2026?

Grammarly Pro is $12 per member a month billed annually, which comes to $144 for the year, or $60 per quarter, or $30 month to month. The free plan costs nothing and includes grammar, spelling, tone detection and 100 AI prompts a month. Enterprise has no published price. Prices are in US dollars by default, with regional pricing in euros, pounds and rupees shown at checkout.

Is Grammarly free?

Yes. The free plan covers spelling, grammar, punctuation and tone detection across the browser extension, desktop app and mobile keyboard, with 100 generative AI prompts a month. It does not include full-sentence rewrites, tone adjustment, plagiarism detection or AI detection, which are the Pro features.

What is the difference between Grammarly Free and Pro?

Pro adds sentence rewrites, tone changes, fluency suggestions, plagiarism and AI-generated text detection, 2,000 AI prompts a member each month, a style guide, a brand tone, two user groups, usage analytics and priority support. Free keeps the error checking and 100 prompts. Pro also carries team features for up to 149 members, since it replaced the old Business plan.

What happened to Grammarly Premium and Grammarly Business?

Both were merged into Pro. Grammarly says Premium subscribers who bought on its website are moved to Pro at no extra cost with the same billing amount, while Premium bought through the App Store or Google Play stays as it was. Pro replaced the Business plan, with the style guide, brand tone and analytics features included in every Pro seat.

Does Grammarly offer a free trial or refunds?

Grammarly periodically offers a seven-day free trial of Pro, with no charge before the trial ends and an immediate switch to the free plan if you cancel during it. Refunds on direct purchases are issued only if required by law, and App Store purchases go through Apple. Subscriptions auto-renew for the same term unless canceled before the period ends.

Is Grammarly Pro included in Superhuman?

The annual Superhuman Pro plan, which Grammarly lists at the same per-member rate as annual Grammarly Pro, includes Grammarly Pro access along with Superhuman Mail, Docs and Go. Monthly Superhuman subscribers, at $15 a month, can add Grammarly Pro as a paid add-on. Existing Grammarly subscribers do not get the suite automatically.

Is Grammarly cheaper than QuillBot?

No. QuillBot Premium is $99.95 a year against the annual Grammarly Pro price, and $19.95 monthly against Grammarly's $30. Grammarly costs more because it bundles plagiarism and AI detection and a team style guide into the seat; QuillBot is the better price for paraphrasing and summarizing alone.
