AI-powered writing assistant focused on grammar, spelling, tone, and clarity improvements across all writing platforms.
Grammarly has transcended its origins as a simple grammar checker to become an essential AI writing assistant used by over 30 million people daily. What started as spell-check evolution has matured into a comprehensive communication platform that improves clarity, tone, engagement, and correctness across every writing surface—from emails and documents to social media posts and Slack messages.
What makes Grammarly indispensable is its ubiquity. The Grammarly extension works everywhere you write: Gmail, Google Docs, Slack, LinkedIn, Twitter, Microsoft Word, Notion—literally any text field in any browser. It's always watching, always ready to help, never intrusive. Write an email in Gmail, and Grammarly suggests improvements in real-time. Draft a LinkedIn post, and it optimizes for professional tone. This seamless, platform-agnostic approach means you get consistent writing assistance regardless of where you're working.
Grammarly's AI goes far beyond basic grammar and spelling. The tone detector analyzes your writing's emotional impact and formality level, helping you strike the right tone for your audience. Clarity suggestions identify convoluted sentences and suggest simpler alternatives. The plagiarism checker (Premium) scans billions of web pages to ensure originality. For teams, Grammarly Business adds brand tone guides, analytics, and centralized style management.
The free tier handles grammar, spelling, and basic suggestions—enough for casual users. Premium ($12/month when billed annually) unlocks advanced features: tone adjustments, clarity improvements, vocabulary enhancement, plagiarism detection, and genre-specific writing style guidance.
