About 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.

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.
