Overview

Real-time grammar, style, and tone suggestions across apps and browsers.

Read detailed overview
Grammarly is an AI writing assistant that works across browsers, desktop apps, mobile apps, documents, email clients, and many workplace tools. It helps users check grammar, spelling, punctuation, clarity, tone, fluency, citations, originality, and AI-generated text while also offering generative AI for drafting, rewriting, brainstorming, and improving written communication. From an expert-review perspective, Grammarly is positioned less as a standalone chatbot and more as an embedded communication layer. Its notable strengths are real-time writing suggestions, multi-app availability, business controls, brand style guidance, AI agents, document scoring APIs, plagiarism detection APIs, and enterprise administration features. Grammarly is well-suited for individuals, students, writers, marketers, support teams, sales teams, HR teams, and enterprises that produce high volumes of written communication. It is especially useful when teams need consistent tone, brand alignment, and writing quality across emails, docs, proposals, tickets, and internal messages. Important considerations include data-processing controls that vary by account type, some advanced governance features being enterprise-focused, and limited transparency around the exact underlying model stack. It is also not an open-source or self-hostable tool.

How is Grammarly different from ChatGPT for writing?
