Grammarly

Overview

Grammarly is an AI writing assistant that helps individuals and teams produce clear, credible text across any app or website. It works as a browser extension, desktop app, mobile keyboard, and within Google Docs and Microsoft Office.

Trusted by over 40 million people and 50,000 organizations, Grammarly provides real-time grammar correction, tone suggestions, and AI-powered rewriting. Unlike basic spell checkers, it adapts to your personal voice and brand style guides while offering plagiarism detection and AI text generation.

Key Benefits

• Improves clarity and flow with one-click paragraph rewrites.
• Adapts your message for the right context with tone suggestions.
• Refines grammar, structure, clarity, and more in real time.
• Detects AI-generated text and suggests areas to revise.
• Trusted by over 40 million people and 50,000 organizations.
• Does not sell or monetize user content or allow third parties to train on user data.

How It Works

You install the Grammarly browser extension or desktop app, then write as usual in any text field — email, document, social post, or chat. Grammarly underlines issues in real time, and you click to accept suggestions for grammar, clarity, tone, or conciseness. You can also highlight a sentence and click "Rewrite" to get a full-sentence alternative, or use the AI prompt box to generate new text from scratch.
