Grammarly's plan lineup is simpler than it used to be and the old names no longer apply. Premium and Business were folded into one tier called Pro, which supports individuals and teams up to 149 members. Pro costs $12 per member per month on annual billing or $30 if you pay month to month — a 150% markup for the flexibility, which is steep even by subscription standards. There's also a quarterly option at $60 for three months. The free plan is genuinely capable rather than a crippled demo, covering real-time grammar, spelling and tone detection plus 100 AI prompts a month; Pro raises that to 2,000 per member. Above 149 seats you're into Enterprise, which is quote-based. Worth knowing: Grammarly's parent company renamed itself Superhuman in late 2025, though the writing product still goes by Grammarly.

For years the Grammarly decision was Premium versus Business, and the internet is full of articles explaining the difference. Both plans are gone. What replaced them is a single tier called Pro that covers individuals and teams up to 149 members.
This is a simplification, and a welcome one. It also means most of the pricing advice you'll find is describing a product that no longer exists.
Here's the current shape:
| Plan | Price | AI prompts |
|---|---|---|
| Free | $0 | 100/month |
| Pro | $12/member/mo annual · $30 monthly | 2,000/member/month |
| Enterprise | Custom quote | Unlimited |
There's a quarterly option too — $60 for three months, averaging $20 a month — which sits between the two in both cost and commitment.
Twelve dollars a month annually. Thirty dollars a month monthly.
That's a 150% premium for flexibility, and it's larger than almost anything comparable in this category. Most tools charge fifteen or twenty percent more for monthly billing. Grammarly charges two and a half times.
Which makes the actual question straightforward: are you going to use this for a year? If you write daily — emails, docs, messages, anything — the answer is almost certainly yes, and paying $144 up front is the obvious move. If you're not sure, the free tier is a better trial than a month of Pro at $30, because it costs nothing and you'll learn the same thing.
One thing to watch: contracts auto-renew, and refund terms are strict. Set a calendar reminder before the renewal date if you're at all uncertain. This is a documented source of frustration among occasional users, and it's entirely avoidable.
Free plans in this category are usually demos with a feature list designed to annoy you into upgrading. Grammarly's isn't.
You get real-time grammar and spelling correction, tone detection, and 100 AI prompts a month, and it works everywhere the extension runs. For someone whose writing is mostly email and Slack, that's the entire job.
What's behind the paywall: full rewrite suggestions, plagiarism detection, AI text detection, and team features like shared style guides and admin controls.
The prompt allowance is where free users feel the ceiling. A hundred sounds fine until you start asking for rewrites regularly, at which point you'll clear it in a couple of weeks. Grammarly doesn't sell top-ups at any tier — you either wait for the reset or you upgrade. Pro's 2,000 per member is generous enough that most people will never think about it again.
Some context, because it confuses people looking at the company.
In October 2025 Grammarly's parent company renamed itself Superhuman. It acquired the spreadsheet startup Rows in February 2026, and in July folded Coda in under the name Superhuman Docs.
The writing product is still Grammarly. Its plans didn't change because of any of this. What did appear is a bundled suite — Grammarly plus a mail client plus docs plus an AI assistant called Superhuman Go — sold on a Business tier around $33 per member per month annually.
Whether that bundle is interesting depends entirely on whether you want an email client and a doc editor. If you just want writing suggestions, standalone Pro at $12 is roughly twenty-one dollars a month cheaper and does the thing you came for. The Enterprise tier is now delivered through Superhuman Go, which is where the two products meet properly.
We're not writing this from a year inside a paid Pro workspace, and it would be easy to imply otherwise on a product this familiar.
The approach was to check Grammarly's current published plans and prompt allowances, then cross-reference against independent pricing analyses published between April and August 2026 — several of which state the date they verified against the live pricing page, with the most recent from within the past few weeks. The corporate rebrand timeline comes from reporting on the company's own announcements.
Sources are unusually consistent on Grammarly, with one exception worth flagging: several trackers list Pro at $30 as the headline price rather than $12, because they're quoting the monthly rate rather than the annual one. Both numbers are correct. They're describing the same plan on different billing cycles, and it's the most common source of confusion in the coverage.
What research doesn't tell you: whether Grammarly's suggestions actually improve your particular writing, or whether the tone detection is useful or irritating for your voice. Those are personal and the free tier answers them for nothing.
Long-form generation. Grammarly improves what you've written. It's not built to produce a two-thousand-word article from a brief. Jasper or a general assistant handles that.
Desktop applications. The browser extension is excellent. Native desktop coverage is less consistent, and some apps won't take it. Test your specific case.
Voice and style. Suggestions trend toward a clean, safe, corporate register. Writers with a distinctive voice often find themselves declining suggestions that would sand it down. That's a real cost if style is part of your value.
Team style enforcement at scale. Pro includes team features, but organizations with serious brand governance requirements — regulated language, compliance-driven terminology — need something built for that. Writer is the category answer.
Against Wordtune: Wordtune is stronger at rephrasing and generating alternative versions of a sentence. Grammarly is stronger at catching what's wrong. If your problem is "this sentence is clumsy," Wordtune. If it's "I don't want to send typos," Grammarly.
Against QuillBot: QuillBot is paraphrase-first and popular with students. It's cheaper and narrower. Grammarly's real-time, works-everywhere positioning is the differentiator.
Against Writer: different buyer entirely. Writer is enterprise infrastructure for brand voice governance and agent workflows, priced accordingly. Grammarly is a personal productivity tool that happens to have team features.
Against ChatGPT or Claude: general assistants will rewrite anything you paste into them, often better than Grammarly's suggestions. What they won't do is sit inside your inbox catching errors you didn't notice. The friction difference is the point.
Against Notion AI: only relevant if your writing lives in Notion. Then it's convenient. Elsewhere it doesn't compete.

Checked August 2026. Grammarly folded the former Premium and Business plans into a single Pro tier supporting up to 149 members; above that, Enterprise applies. Prompt top-ups are not sold at any tier. The parent company renamed itself Superhuman in October 2025, and a bundled Superhuman Business suite sits at roughly $33 per member per month annually. Verify current rates on Grammarly's pricing page before purchasing.
Pay annually or use free. The monthly rate is two and a half times the annual one. There's no middle ground that makes sense unless you genuinely need a three-month window.
Diarize your renewal. Auto-renewal plus strict refund terms is a combination that catches people out.
Try free properly first. It's capable enough that you'll know within a week whether Pro's additions matter to you.
Skip the suite unless you want the email client. Standalone Pro is substantially cheaper and covers the writing use case completely.
Grammarly remains the default answer to a specific question: how do I stop sending writing with mistakes in it, without changing how I work? Nothing else covers as many places you type, as unobtrusively, with as little setup.
The plan consolidation is a genuine improvement. One paid tier that scales from an individual to a 149-person team removes a decision nobody enjoyed making. The pricing is fair at $12.
The monthly rate is not fair at $30. That's the one thing worth being blunt about. Pay annually or stay on free — the middle option is poor value and the free tier is good enough to make the choice easy.
The limitations are the same ones this product has always had. It corrects rather than creates. It nudges toward a neutral register that writers with a voice will sometimes resist. Desktop coverage lags the browser experience. None of these are surprises, and none of them undermine the core case.
For anyone who writes daily in a browser, Pro at the annual rate is straightforwardly worth it. For casual writers, free covers more than you'd expect and there's no urgency to upgrade. For organizations with real brand governance requirements, this isn't the right category of product.

Best for: Daily writers working in browsers, professionals sending high volumes of email, non-native English speakers, small teams wanting shared style consistency Not ideal for: Long-form content generation, writers with a distinctive voice they need protected, organizations needing enterprise brand governance, users working primarily in desktop applications Bottom line: The best real-time writing assistant available, simplified into one sensible paid tier. Pay annually — the monthly rate is the only genuinely bad deal here.
Three tiers. Free is $0. Pro is $12 per member per month billed annually, which works out to $144 up front, or $30 per member per month if you pay monthly. A quarterly option sits between them at $60 for three months, averaging $20 a month. Enterprise is custom-quoted. The gap between annual and monthly is unusually wide — you're paying two and a half times as much for the ability to cancel any month, which is worth thinking about before you default to monthly.
They no longer exist as separate plans. Grammarly consolidated both into the single Pro tier, which now serves individuals and teams up to 149 members. If you're comparing an older guide that walks through the differences between Premium and Business, it's describing a lineup that's been retired. For teams above 149 seats, Enterprise is the path, and it's now positioned through the Superhuman Go product alongside Grammarly.
Better than most free tiers in this category, and not a stripped-down trial. You get real-time grammar and spelling correction, tone detection, and 100 AI prompts a month, working everywhere the browser extension reaches. For a lot of people that covers the actual need. What you don't get is full rewrite suggestions, plagiarism detection, AI text detection, or team features. If your writing is email and Slack messages and you mainly want typos caught, free is likely enough.
A prompt is any time you ask Grammarly to do generative work — rewrite a paragraph, draft a reply, explain why a suggestion was made. Free gives you 100 a month, Pro gives 2,000 per member, and Enterprise removes the cap. The catch is that Grammarly doesn't sell top-ups, so if you exhaust your allowance you wait for the monthly reset or you upgrade. For most Pro users 2,000 is comfortably more than they'll use; on free, 100 goes quickly if you lean on the rewrite feature.
The parent company rebranded, not the product. In October 2025 the company renamed itself from Grammarly to Superhuman, then acquired the spreadsheet startup Rows in February 2026 and folded Coda in as Superhuman Docs in July 2026. The writing assistant is still called Grammarly and its plans didn't change as a result. What did emerge is a bundled Superhuman suite — writing assistant, mail client, docs and an AI assistant — on a Business tier around $33 per member per month annually. If you just want writing help, standalone Pro is the cheaper answer.
Broadly yes, in browsers. The extension covers Gmail, Google Docs, Slack, LinkedIn, and the vast majority of web-based text fields, and there are desktop apps for macOS and Windows plus mobile keyboards. Where it gets patchy is native desktop software — the desktop integration works but is noticeably less reliable than the browser extension, and some applications simply don't accept it. If most of your writing happens in a specific desktop program, test that specific case before subscribing.
They're solving different problems that overlap at the edges. Grammarly sits inside whatever you're already writing and corrects in real time without you asking. ChatGPT is a separate destination you go to for generation and heavier rewriting. If you want your existing writing improved as you produce it, Grammarly's positioning is the whole value. If you want text produced from scratch, a general assistant does that better. Plenty of people pay for both without it feeling redundant.
