Grammarly Pricing: Free vs Premium vs Business (2026)

Grammarly has evolved from a simple spell-checker into a full AI writing assistant used by over 30 million people daily. The pricing structure is straightforward: three main tiers — Free, Premium, and Business — plus an Enterprise plan for large organizations. Whether you're a student polishing essays or a 200-person marketing team keeping brand voice consistent, there's a plan that fits.

Here's the full breakdown of every Grammarly plan available right now:

The most important thing to notice: Grammarly Premium's annual plan works out to $12/month — a 60% discount over the $30/month billed monthly. That's a massive difference, and the annual plan is what Grammarly clearly wants you on. You can check the latest details on the official Grammarly pricing page.

Grammarly's free tier is legitimately useful — not a crippled demo designed to frustrate you into upgrading. Here's exactly what you get at $0:

Writing Corrections

• Grammar and spelling checks — catches subject-verb agreement errors, misused words, misspellings, and typos across everything you write
• Punctuation corrections — commas, semicolons, apostrophes, and the serial Oxford comma debate handled automatically
• Conciseness suggestions — flags wordy phrases and suggests tighter alternatives (e.g., "in order to" becomes "to")
• Basic tone detection — tells you if your writing sounds formal, informal, confident, or friendly (but no rewrite suggestions)

GrammarlyGO AI Assistant (Limited)

• 100 AI prompts per month — you can ask GrammarlyGO to rewrite paragraphs, change tone, generate text, or brainstorm ideas
• Works across all platforms — the browser extension, desktop app, mobile keyboard, and integrations all share the same prompt pool
• Basic text generation — compose emails, replies, and short-form content from prompts

Platform Support

• Browser extensions — Chrome, Firefox, Safari, Edge
• Desktop apps — Windows and macOS native applications
• Mobile keyboard — iOS and Android
• Integrations — works inside Google Docs, Microsoft Word, Gmail, Outlook, Slack, Discord, and hundreds more
• Grammarly Editor — web-based document editor at app.grammarly.com

For students writing occasional papers, professionals who want a safety net for emails, or anyone who just wants to catch embarrassing typos — Free handles all of that. The 100 GrammarlyGO prompts per month is enough for light use, maybe 3-4 AI rewrites per day. Where Free falls short is when you need advanced style suggestions, plagiarism detection, or the full power of GrammarlyGO for heavy daily writing.

Premium is where Grammarly transforms from a proofreading tool into a genuine writing coach. Here's everything you gain:

Advanced Writing Suggestions

• Full-sentence rewrites — not just flagging problems, but rewriting entire sentences to be clearer, more engaging, or more appropriate for your audience
• Clarity-focused restructuring — identifies convoluted sentence structures and suggests simpler alternatives that preserve your meaning
• Vocabulary enhancement — suggests more precise or impactful word choices, not just synonyms from a thesaurus
• Tone adjustments — rewrites text to sound more confident, diplomatic, constructive, or whatever tone you need. Free tells you the tone; Premium changes it.
• Formality level detection — flags when your writing is too casual for a business email or too formal for a Slack message

Plagiarism Checker

• Scans against 16+ billion web pages — checks your text for unintentional similarity to published content
• Academic and professional databases — includes ProQuest academic sources
• Unlimited checks — run as many plagiarism scans as you need, no per-check fees
• Source citations — shows exactly where matching text was found so you can properly attribute or rewrite

GrammarlyGO AI (Expanded)

• 1,000 AI prompts per month — 10x the Free allocation, enough for heavy daily use
• Advanced rewrites — longer, more nuanced text transformations including full-paragraph and multi-paragraph rewrites
• Personalized voice profiling — GrammarlyGO learns your writing style over time and generates text that sounds like you, not like a chatbot
• Context-aware suggestions — understands the document you're working in and tailors suggestions to the subject matter and audience

Additional Premium Features

• Writing style consistency — ensures consistent formatting, terminology, and tone throughout longer documents
• Genre-specific checks — different suggestion profiles for academic writing, business documents, creative fiction, technical documentation, and casual communication
• Performance statistics — weekly writing insights including word count, accuracy, vocabulary diversity, and improvement trends

At $12/month on the annual plan, Premium replaces what would cost significantly more if you bought a plagiarism checker (Turnitin starts at $75/year for individuals), a separate AI writing assistant, and a grammar tool separately. For anyone who writes professionally — content creators, marketers, academics, copywriters — Premium is where the real value lives.

Grammarly Business wraps everything in Premium plus team-specific features designed for organizations that need consistent, on-brand communication.

Brand Tones and Style Guides

This is the killer feature for teams. You define your company's voice — maybe "professional but approachable, avoid jargon, always use Oxford comma" — and every team member gets real-time suggestions aligned to that voice. No more one writer sounding corporate while another sounds like they're texting a friend. Custom style guides let you enforce specific terminology ("customers" not "users"), banned words, preferred phrases, and formatting rules across the entire organization.

Snippets

Pre-built text blocks that team members can insert with a shortcut. Customer support responses, standard email signatures, common boilerplate — saved once, used everywhere. Keeps messaging consistent and saves typing time.

Analytics Dashboard

See writing quality metrics across your team: who's using Grammarly, how writing accuracy is trending, what common mistakes are being caught, and how much time is being saved. Useful for managers who want to justify the investment and identify team members who might need additional writing training.

The minimum of 3 members means your entry cost is $540/year ($180/member/year). For a customer-facing team — sales, marketing, support — the consistency in communication quality pays for itself quickly. If your team sends thousands of emails per week, even a small improvement in clarity and professionalism compounds into real business impact.

GrammarlyGO is Grammarly's generative AI layer, built on top of their existing writing assistant. It launched in 2023 and has been continuously expanded since. Here's what it actually does — and where each tier gets access.

What GrammarlyGO Can Do

• Compose from prompts — write emails, messages, documents, and replies from brief instructions. Tell it "write a polite follow-up email about the delayed shipment" and get a ready-to-send draft.
• Rewrite text — select any text and ask GrammarlyGO to make it shorter, longer, more formal, more casual, simpler, or more engaging. Full paragraph rewrites, not just word swaps.
• Change tone — transform the same message to sound confident, diplomatic, empathetic, direct, or friendly. Useful for sensitive emails where getting the tone right matters.
• Ideate and brainstorm — generate outlines, talking points, counterarguments, and content ideas based on your topic.
• Reply suggestions — in email and messaging platforms, GrammarlyGO reads the incoming message and suggests contextually appropriate replies.
• Summarize — condense long documents, email threads, or articles into key points.

GrammarlyGO Prompt Limits by Plan

The prompt limits reset monthly. For most individual users, 1,000 prompts on Premium is more than enough — that's 33 AI interactions per day, every day. You'd have to be using GrammarlyGO for every single email and message to hit that ceiling. The 100 Free prompts, however, run out fast if you're relying on AI rewrites as part of your daily workflow.

How GrammarlyGO Compares to ChatGPT for Writing

GrammarlyGO isn't trying to be ChatGPT. Its strength is contextual writing assistance embedded where you already write — inside Gmail, Google Docs, Slack, Word, and everywhere else the Grammarly extension works. You don't copy-paste text to a separate chatbot window. The AI works inline, in context, understanding the platform and conversation you're in. For pure writing assistance, that embedded experience is more efficient than switching to a standalone AI chat. For broader tasks like research, analysis, or creative brainstorming, a dedicated AI assistant like ChatGPT or Claude is more capable.

Grammarly isn't the only writing assistant out there. Here's how it compares to the two most common alternatives:

When to Choose Grammarly

You write across many platforms every day — emails, Slack messages, documents, social media — and you want corrections everywhere automatically. Grammarly's browser extension and integrations make it invisible: it just works wherever you type. The GrammarlyGO AI assistant adds genuine value for composing and rewriting. If writing is part of your daily job (not your main craft), Grammarly is the right choice.

When to Choose ProWritingAid

You're a long-form writer — novelist, academic, blogger, technical writer — who cares deeply about style, not just correctness. ProWritingAid's 25+ writing reports (readability, sentence variety, pacing, dialogue tags, cliches, and more) go far deeper than Grammarly's suggestions. The $120/year price is slightly cheaper, and the $399 lifetime deal is unbeatable if you'll use it for years. The Scrivener integration is a must-have for novelists. Where it falls short: no mobile keyboard, less polished browser extension, and no AI assistant that matches GrammarlyGO.

When to Choose Hemingway Editor

You need a quick readability check and nothing more. Hemingway highlights complex sentences, passive voice, adverb overuse, and hard-to-read passages in a clean, color-coded interface. The web editor is free. The desktop app is a one-time $10 purchase — no subscriptions. It's intentionally simple: paste text in, see what needs simplifying, fix it. If you already have a grammar checker and just want a readability tool, Hemingway is perfect. It's not a Grammarly replacement — it's a complement.

Can You Use Them Together?

Yes. Many writers use Grammarly for daily email and messaging (browser extension), ProWritingAid for deep editing on long documents, and Hemingway for a final readability pass. There's no conflict between the tools, and each excels at different things. The combination of Grammarly Premium ($144/yr) + Hemingway ($10 one-time) covers most professional writing needs without overlap.

Grammarly's discount situation for students is less generous than tools like Canva (which gives Pro away free to educators), but there are legitimate ways to save.

Grammarly@edu (Institutional Licenses)

Many universities and colleges purchase Grammarly Business or Enterprise licenses for their students and faculty. If your institution has a Grammarly@edu agreement, you get full Premium access for free through your school email. Over 3,000 educational institutions worldwide have these agreements.

How to check: Log into Grammarly with your .edu email address. If your school has a license, you'll automatically get Premium features. You can also check with your university's IT department, writing center, or library — they often manage the Grammarly institutional subscription.

Individual Student Discounts

Grammarly periodically offers student discounts of 20-40% off Premium, usually through email campaigns or partner promotions. These aren't always publicly advertised. Here's how to find them:

• Sign up with your .edu email — Grammarly sometimes targets .edu addresses with exclusive discount offers
• Check UNiDAYS and Student Beans — Grammarly has appeared on both platforms with verified student discounts
• GitHub Student Developer Pack — occasionally includes Grammarly Premium as a partner benefit
• Back-to-school promotions — August and September often bring the best student deals, sometimes up to 50% off annual plans

Grammarly for Education (Free Writing Resources)

Even without a paid plan, Grammarly offers free educational resources: a plagiarism checker for citations, writing handbooks, and the Grammarly Blog's writing tips. The Free tier's grammar and spelling checks handle most academic writing needs. Many students use Grammarly Free through their entire degree without needing Premium — the plagiarism checker is the main Premium feature that students typically want, and many universities provide Turnitin separately.

The bottom line for students: Check your school's institutional access first — it's the easiest path to free Premium. If your school doesn't have it, the Free tier plus your university's existing plagiarism tool (usually Turnitin) covers most academic needs. Only pay for Premium if you specifically need Grammarly's plagiarism checker or the advanced AI writing features.

The honest assessment, not the affiliate marketing pitch.

When Premium Is 100% Worth It

You write professionally every day. If your job involves writing emails, reports, proposals, or content — and your professional reputation depends on the quality of that writing — Premium's advanced suggestions catch things Free misses. Tone adjustments alone can save you from sending a message that reads as passive-aggressive when you meant constructive. Over a month of daily emails, that's worth $12.

You need the plagiarism checker. If you're creating original content — blog posts, articles, academic papers, marketing copy — and you need to verify it's not accidentally similar to existing published content, Grammarly's plagiarism checker is one of the best available. A standalone plagiarism tool would cost $8-20/month; bundled with everything else Premium offers, it's a bargain.

You rely on AI writing assistance. If you use GrammarlyGO regularly for composing emails, rewriting paragraphs, or changing tone, the 100 Free prompts will run out within the first week. Premium's 1,000 monthly prompts give you the headroom to use AI assistance as a genuine part of your workflow rather than rationing it.

English isn't your first language. Grammarly Premium's full-sentence rewrites and clarity suggestions are particularly valuable for non-native English writers. It doesn't just fix errors — it restructures sentences to sound natural, which is much harder than correcting grammar.

When Premium Is Not Worth It

You only write a few emails a day. If your writing is limited to short emails and the occasional document, Free catches the important stuff. The advanced suggestions Premium adds are nice but not essential for casual writing volume.

You're a skilled writer who just wants a safety net. If you write well and just want to catch the occasional typo or missed comma, Free does that perfectly. Premium's style suggestions may even annoy you — experienced writers often disagree with AI suggestions about how to phrase things.

You already use a dedicated AI writing tool. If you have ChatGPT Plus, Claude Pro, or another AI assistant for writing tasks, the GrammarlyGO features overlap significantly. You might only need Grammarly Free for the inline grammar checking and use your AI assistant for the heavy lifting.

The Verdict

For professionals who write daily, non-native English speakers, and content creators, Grammarly Premium at $12/month (annual) is one of the most justifiable software subscriptions you can have. The combination of advanced corrections, plagiarism checking, and GrammarlyGO makes it a genuine productivity multiplier. But if you write casually and have other AI tools, Free is honestly fine. Don't let the upgrade prompts pressure you.

Before you pay full price, try these strategies:

1. Always Choose Annual Billing

Grammarly Premium monthly is $30/month ($360/year). Annual is $144/year ($12/month). That's a $216 savings — a 60% discount. This is one of the biggest monthly-vs-annual gaps in all of SaaS. If you've been using Grammarly Free for a month and want to upgrade, the annual plan is the only sensible choice.

2. Check Your School or Employer

Over 3,000 universities and thousands of businesses provide Grammarly through institutional licenses. You might already have free access to Premium or Business through your school email or corporate SSO. Always check before buying an individual plan — you could be paying for something you already have.

3. Use the 7-Day Free Trial

Grammarly Premium offers a 7-day free trial. It's shorter than most SaaS trials, so plan it strategically. Activate it during a week when you have significant writing work — a batch of blog posts, a major proposal, or a thesis chapter. You'll get real work done and a genuine sense of whether Premium's suggestions make a meaningful difference for your writing.

4. Watch for Seasonal Promotions

Grammarly runs promotions around Black Friday (often 50-60% off annual plans), back-to-school season, New Year, and occasionally during summer. These are the best times to lock in an annual plan at a reduced rate. If you're on the fence, wait for Black Friday — it's consistently their best deal.

5. Consider ProWritingAid's Lifetime Deal

If you're comparing options, ProWritingAid offers a $399 lifetime license. If you'd use a writing assistant for 3+ years, that works out cheaper than Grammarly Premium's ongoing subscription ($144/year). ProWritingAid lacks Grammarly's polished integrations and GrammarlyGO, but its deep style analysis is superior for long-form writing. Worth considering if subscription fatigue is real for you.

Grammarly's pricing is simple: three tiers, each adding meaningfully over the last, with no hidden fees or confusing add-ons.

Grammarly Free is genuinely useful for everyday writing. Grammar, spelling, punctuation, and basic tone detection — with 100 GrammarlyGO AI prompts per month. For students and casual writers, it's more than enough. The browser extension alone makes your writing better everywhere without any effort.

Grammarly Premium at $12/month (annual) is the sweet spot for professionals. Full-sentence rewrites, plagiarism detection, 1,000 AI prompts, tone adjustments, and advanced clarity suggestions make it a complete writing toolkit. If writing is part of your job — not just emails, but actual writing that represents you or your company — this is the plan.

Grammarly Business at $15/member/month (annual) is the right call for teams that care about communication quality. Brand tones, custom style guides, snippets, and analytics transform scattered individual writing into consistent company-wide communication. The per-member cost is only $3 more than Premium, and the team features add genuine value.

Compared to competitors: Grammarly is more expensive than ProWritingAid ($120/yr vs $144/yr) but offers a more polished experience, better integrations, and a superior AI assistant. It's infinitely more expensive than Hemingway ($10 one-time) but does infinitely more. For most people, the question isn't Grammarly vs alternatives — it's Grammarly Free vs Premium.

If you're deciding right now: install the free browser extension, use it for a week, and see if the Premium upgrade prompts on advanced suggestions make you wish you had them. If they do, lock in the annual plan. If Free is handling everything you need, save your money.
