Grammarly

Grammarly is an AI writing assistant that supports the full path from first draft to final edit. It checks spelling, punctuation, grammar, clarity, concision, and tone, then offers suggestions that can be accepted inline. Full-sentence rewrites help reshape a paragraph quickly, while tone adjustments can make a message more formal, friendly, or appropriate to its context without requiring a separate editor. Beyond proofreading, Grammarly includes AI agents and writing tools for paraphrasing, proofreading, reader-reaction feedback, text generation, AI-generated-text detection, plagiarism detection, and citation support. Its Docs editor provides a dedicated space for longer writing, and multilingual assistance includes real-time support in more than 20 languages, with translation and paragraph-level rewrites in multiple languages. For organizations, Grammarly can apply custom style rules, brand tones, shared snippets, and company knowledge so teams communicate consistently. Analytics help teams review writing performance and improvement. Grammarly is designed to work across more than one million apps and websites, including Gmail, Outlook, Google Docs, Microsoft Word, Slack, Microsoft Teams, PowerPoint, Apple Mail, Notion, LinkedIn, Facebook, and Figma, with browser extensions, desktop apps, mobile apps, and an editor. It serves individuals, students, professionals, educators, and larger teams.
