Freemium250,000 ReviewsOur Verdict
Best for: Best for anyone who writes regularly in English and wants real-time, context-aware writing assistance that works seamlessly across every app and platform they use.
Grammarly occupies a unique and nearly unchallenged position in the writing tools market. While AI chatbots like ChatGPT and Claude can help you write from scratch, Grammarly excels at making your existing writing better, right where you are already working. Its platform ubiquity is unmatched: no other writing tool integrates as seamlessly across as many applications and surfaces. The addition of GrammarlyGO brings generative AI capabilities into the mix without disrupting the core proofreading experience that made Grammarly indispensable for millions. The tone detector alone is worth the price of admission for professionals who need to navigate sensitive communications. For non-native English speakers, Grammarly is arguably the single most valuable software investment they can make for their careers. The Premium plan is reasonably priced for the value it delivers, and the Business tier is a smart investment for any organization that cares about professional communication standards. Grammarly is not trying to replace your AI chatbot; it is trying to make every word you write better, and it succeeds at that mission remarkably well.

Pros
- Works seamlessly across 500,000+ apps and websites through browser extensions, desktop apps, and mobile keyboards, providing consistent writing assistance everywhere you type.
- Context-aware suggestions adapt to your writing goals, audience, and tone, delivering genuinely useful feedback rather than generic grammar rules that ignore intent.
- GrammarlyGO integrates generative AI directly into the writing workflow, allowing users to compose, rewrite, and ideate without leaving their current application.
- The tone detection feature provides real-time feedback on how your writing will be perceived by readers, helping you strike the right emotional note in sensitive communications.
Cons
- The Premium plan at $12 per month (annual billing) may feel expensive for individual users, especially students, considering that basic grammar checking is available in many free tools.
- Grammarly can occasionally be overly prescriptive with style suggestions, flagging intentional stylistic choices like sentence fragments, colloquialisms, or creative phrasing as errors.
- The generative AI features in GrammarlyGO, while convenient, are less capable than dedicated AI assistants like ChatGPT or Claude for complex writing tasks, long-form content, or creative work.

Pricing Details
Grammarly offers a well-structured freemium pricing model with clear value at each tier. The free plan is genuinely useful, providing core grammar, spelling, and punctuation corrections along with basic tone detection and conciseness suggestions. For many casual writers, the free tier provides sufficient value for everyday use, making it one of the more generous free offerings among writing tools. It works across all platforms and integrations without restriction, which is a significant advantage over competitors that limit free access to specific surfaces. Grammarly Premium is priced at $12 per month when billed annually ($30 per month if billed monthly) and unlocks the full suite of writing assistance features. This includes advanced clarity and sentence rewriting suggestions, vocabulary enhancement recommendations, tone adjustments, formality level detection, fluency corrections for non-native speakers, and the full plagiarism checker with access to ProQuest academic databases. Premium also includes full access to GrammarlyGO with 1,000 AI prompts per month for generative writing tasks. For anyone who writes regularly in a professional capacity, the Premium tier represents strong value. Grammarly Business starts at $15 per member per month (billed annually, minimum 3 seats) and adds organizational features including brand tone profiles, style guides, snippet libraries, centralized admin controls, and team analytics dashboards. The Enterprise tier offers custom pricing and adds SAML SSO, SCIM provisioning, custom security controls, dedicated customer success management, and priority support. Grammarly also offers a special education discount for students and educators, as well as volume pricing for larger organizations. Compared to hiring a human proofreader or editor, even the Premium plan offers extraordinary cost savings, particularly for teams producing high volumes of written content.

About Grammarly
Grammarly has evolved from a simple grammar checker into the most comprehensive AI-powered writing assistant available, used by over 30 million people and 70,000 professional teams worldwide. The platform operates as an always-on writing companion that works seamlessly across virtually every digital surface where you type, from email clients and word processors to social media platforms and messaging apps. Its real-time suggestions cover grammar, spelling, punctuation, clarity, conciseness, tone, and inclusive language, making it far more than a spell checker. What makes Grammarly particularly effective is its contextual understanding of writing intent. Rather than applying rigid rules universally, Grammarly adapts its suggestions based on the type of content you are writing, your audience, and your desired tone. Writing a casual Slack message to a colleague triggers different suggestions than drafting a formal business proposal or an academic paper. This contextual intelligence reduces false positives and makes the feedback genuinely useful rather than pedantic. The platform's AI capabilities have expanded significantly with the introduction of GrammarlyGO, a generative AI feature that goes beyond corrections to actively help compose, rewrite, and ideate text. Users can prompt GrammarlyGO to draft replies, rephrase paragraphs for different tones, summarize long documents, or generate content from scratch, all within the same interface they already use for proofreading. This integration of generative AI into an established writing workflow is remarkably smooth and eliminates the need to switch between a grammar tool and a separate AI chatbot. For business users, Grammarly Business adds brand tone profiles, style guides, snippet libraries, and analytics dashboards that ensure consistent communication across entire organizations. The enterprise offering includes SAML SSO, SCIM provisioning, and data governance controls. Grammarly's ubiquity is its greatest advantage: it works in over 500,000 apps and websites through browser extensions, desktop applications, mobile keyboards, and direct integrations with tools like Microsoft Office, Google Docs, and Notion. This platform-agnostic approach means your writing assistance follows you everywhere, creating a seamless experience that no competitor has matched in breadth of coverage.
