Grammarly Pricing Guide 2026: Free vs Premium vs Business

Grammarly started as a grammar checker. It's evolved into a full writing assistant that catches tone problems, rewrites unclear sentences, and — in Premium — checks for plagiarism. The free plan is more capable than many people realize, which makes the upgrade decision less obvious than Grammarly's marketing would have you believe.

This guide breaks down what each plan actually does, where the free tier falls short, and who should not bother paying.

Grammarly Plan Overview

| Plan | Price | Best For | |------|-------|----------| | Free | $0 | Casual writers who need basic error catching | | Premium | $12/mo (annual) or $30/mo (monthly) | Content creators, professionals, students | | Business | $15/user/mo (annual, min 3 users) | Teams needing style guides and admin controls | | Enterprise | Custom | Large organizations with compliance needs |

Grammarly Free — Better Than You Think

The free plan catches real errors. Spelling, basic grammar, punctuation — things like comma splices, subject-verb disagreement, and misspelled words. It also catches some wordiness and flags unclear pronoun references.

What Free includes:

• Spelling and grammar corrections
• Basic punctuation checks
• Conciseness suggestions (some)
• Browser extension for Chrome, Firefox, Edge, Safari
• Desktop app for Windows and Mac
• Mobile keyboard (iOS and Android)
• Integration with Google Docs (basic)
• 100 AI prompts per month (Grammarly AI rewrites)

What's missing:

• Tone detection and adjustment suggestions
• Clarity rewrites for complex or wordy sentences
• Full style and delivery suggestions
• Plagiarism checker
• Vocabulary enhancement suggestions
• Full sentence rewrite recommendations
• Unlimited AI prompts

For someone writing emails, Slack messages, or casual blog posts, the free plan catches most real mistakes. The gap between free and premium shows more clearly in longer-form writing where style, clarity, and tone matter.

Grammarly Premium — $12/month (Annual)

Premium is priced at $12/month when billed annually ($144/year total). Monthly billing is $30/month — a significant premium over the annual rate. If you're committing to Grammarly, annual is almost always the right choice.

What Premium adds:

• Clarity-focused rewrites — suggests restructuring sentences that are technically correct but hard to parse
• Tone detection — flags when your writing comes across as aggressive, passive, or inconsistent
• Style suggestions — catches formality mismatches, wordiness, and vague language
• Plagiarism checker — checks against 16 billion web pages
• Vocabulary enhancements — suggests more precise or varied word choices
• Full delivery suggestions — pacing, engagement, confidence
• Unlimited Grammarly AI prompts

Where Premium earns its keep:

The clarity rewrites are the most underrated feature. Grammar checkers catch errors, but they rarely catch writing that's technically correct but hard to read. Premium surfaces sentences like "The meeting was had by the team on Thursday" and suggests "The team met Thursday" — not a grammar error, but a real improvement.

Tone detection is useful if you write a lot of client-facing content or professional emails where the wrong register can damage a relationship. It's not perfect — it occasionally flags decisive language as "blunt" — but it catches real problems often enough to be worth having on.

The plagiarism checker is a meaningful add-on for content marketers and students. It's not as comprehensive as Copyscape, but it's convenient and covered by the subscription.

Where Premium falls short:

Grammarly Premium does not fix bad writing. It can improve clarity and catch tone issues, but if the underlying argument or structure is weak, no amount of sentence-level suggestions will save it. It also occasionally over-suggests — flagging perfectly good prose as needing revision because it's tuned toward a generic readable style.

The AI rewrite tool (Grammarly AI) has improved but it's not a replacement for a skilled editor. It tends toward safe, generic phrasing and can drain the voice out of writing that has personality.

Grammarly Business — $15/user/month (Annual, Minimum 3 Users)

Business adds team management features on top of Premium. The minimum is 3 users, so the floor is $45/month ($540/year).

What Business adds over Premium:

• Team style guide — define rules for your brand voice (preferred terminology, forbidden phrases, formatting preferences)
• Snippets — shared text shortcuts for frequently used phrases
• Admin dashboard — usage analytics, team member management
• Priority support
• Centralized billing
• SAML SSO (on qualifying plans)

When Business is justified:

If you have a content team, marketing writers, or customer support staff writing external-facing copy, the style guide feature is the main draw. You can enforce things like "never use 'leverage' as a verb" or "always write out numbers under ten" across the whole team without relying on a written style guide that no one reads.

The analytics dashboard lets admins see how actively team members are using Grammarly — useful if you're paying for seats you're not sure are getting used.

When Business isn't justified:

If your team is 2 people, you're paying for 3 seats. The style guide can partially be replicated by sharing a document with writing rules. For small teams where everyone already writes well, the incremental value over individual Premium plans is thin.

At $15/user/month vs $12/user/month for Premium, the gap is $36/user/year. For a 5-person team, that's $180/year extra for admin controls and style guide. Whether that's worth it depends on how disciplined your brand voice needs to be.

Grammarly vs Built-in AI Writing Tools

Grammarly now competes directly with AI writing assistants that are either free or bundled with tools people already pay for.

| Tool | Cost | Grammar | Style Suggestions | Tone | Plagiarism | AI Rewrites | |------|------|---------|------------------|------|-----------|-------------| | Grammarly Free | Free | Strong | Basic | No | No | Limited | | Grammarly Premium | $12/mo | Strong | Full | Yes | Yes | Unlimited | | Microsoft Editor (M365) | Included in M365 | Moderate | Limited | Basic | No | Via Copilot | | Google Docs AI | Free | Basic | Limited | No | No | Via Gemini | | ChatGPT (free) | Free | Via prompts | Via prompts | Via prompts | No | Yes | | Claude (free) | Free | Via prompts | Via prompts | Via prompts | No | Yes |

The honest comparison: if you're comfortable pasting text into ChatGPT or Claude and asking for a rewrite, you can get equivalent or better style suggestions for free. The advantage Grammarly has is integration — it works inline in your browser, email client, and Google Docs without a copy-paste workflow.

For someone who writes entirely in Google Docs and is comfortable with AI tools, the value proposition of Grammarly Premium has weakened. The inline suggestions and tone detection remain genuinely convenient, but "free AI chatbot does it too" is a real alternative for budget-conscious users.

Microsoft Editor is included with Microsoft 365 subscriptions and covers most basic grammar checking. If you're already paying for M365, it's worth trying before paying for Grammarly.

Grammarly for Specific Use Cases

Content creators and bloggers: Premium is worth it. The tone and clarity features help with writing that needs to hold a reader's attention, and the plagiarism checker is a useful sanity check before publishing.

Students: The free plan covers most academic writing needs. Premium adds the plagiarism checker, which is valuable before submitting papers. The annual plan at $144 can be expensive for students — check if your institution offers Grammarly access through a university license.

Email-heavy professionals: The free browser extension catches most errors in email. The tone detection in Premium is useful if you're writing a lot of sensitive communications, but it's not essential.

Technical writers: Grammarly is not well-suited to technical writing. It doesn't understand domain-specific style guides, flags jargon that's intentional, and sometimes rewrites precise technical language into vaguer prose. Use it with caution in this context.

Customer support teams: Business tier with the style guide is worth considering if consistency matters across a support team. Without it, agents develop inconsistent voices that can confuse customers.

Who Should NOT Buy Grammarly Premium

• People who write infrequently — If you're writing one document a month, the free plan is enough. Don't pay $144/year for occasional use.
• Developers and technical writers — Grammarly regularly interferes with code blocks, misunderstands technical jargon, and suggests rewrites that make technical content less precise.
• Writers with a strong established voice — Grammarly's suggestions trend toward a generic readable style. If you've deliberately developed a distinct voice, the constant suggestions to "simplify" can be more annoying than helpful.
• People already paying for ChatGPT Plus — ChatGPT Plus includes access to GPT-4, which handles rewrites, tone adjustment, and grammar correction more flexibly than Grammarly. The main thing you lose is inline browser integration.
• Small teams where only one person writes externally — One Premium license is $144/year. Business minimum (3 seats) is $540/year. Don't pay for seats that aren't earning their keep.

Pricing Tips

Annual vs monthly: Monthly billing at $30/month is $360/year. Annual at $12/month is $144/year. The difference is $216/year. If you plan to use Grammarly for more than 6 months, annual billing is straightforwardly better.

Student discounts: Grammarly periodically offers student discounts, particularly at the start of academic semesters. Check their website in August and January.

Free trial: Grammarly offers a free trial of Premium. Use it to assess how many of its suggestions you actually act on before committing. If you're dismissing most suggestions, the free plan is probably enough.

One account, multiple devices: Grammarly Premium works across all your devices with one subscription — browser extension, desktop app, mobile keyboard. No per-device fees.

FAQs

Does Grammarly work with Microsoft Word? Yes. Grammarly has a Word add-in for Windows. Mac support has historically been through a separate app rather than a native add-in, but integration has improved. Check the current compatibility on Grammarly's website before assuming full Word integration.

Can Grammarly see everything I type? Grammarly's browser extension reads text in fields where it's active. This is a privacy consideration for sensitive documents. Grammarly states they don't sell text data and use encryption, but if you're working with confidential information, disable the extension for sensitive applications or use the desktop app with explicit document selection.

Is the plagiarism checker accurate? It's useful for catching obvious lifted content but shouldn't be the only check for academic or SEO content where plagiarism has real consequences. Copyscape or Quetext offer more comprehensive checks for professional content.

Does Grammarly work in Gmail and Outlook? Yes. The browser extension integrates with Gmail in Chrome/Firefox, and Grammarly has an Outlook add-in for Windows.

What's the refund policy? Grammarly offers refunds within a limited window after purchase. Contact their support team — their refund policy is better than many SaaS tools but check current terms before purchasing.

Conclusion

Grammarly Free catches real errors and is worth installing even if you never upgrade. For casual writers, it's enough.

Premium earns its cost for people who write regularly for an audience — content creators, professionals producing client communications, or anyone where writing quality directly affects their reputation or income. The tone detection and clarity rewrites are the features that differentiate it from just running text through a free AI tool.

Business makes sense for teams that need consistent brand voice across multiple writers, but the minimum 3-seat requirement means you should have all three seats actively used before committing.

If you're on the fence, use the free trial to measure how often you actually accept Premium suggestions. That number tells you whether the upgrade is worth it.
