What is Grammarly?

Grammarly is an AI writing assistant that checks what you type and suggests fixes as you go. It catches typos, punctuation and grammar errors, shows the tone of a message, and on paid plans rewrites full sentences, adjusts tone in a click and generates text from prompts. AI agents such as Paraphraser, Proofreader and Reader Reactions help at different stages, and Docs gives you a dedicated AI editor for longer writing. The service works across more than 1 million apps and websites, including Gmail, Outlook, Google Docs, Microsoft Word, Slack, Teams and LinkedIn, and supports writing help in more than 20 languages. Students, professionals and teams use it for emails, reports and brand-consistent communication. Team features include style guides, brand tones, snippets, Knowledge Share and analytics. Free costs $0 and includes 100 AI prompts a month, Pro is $12 with 2,000 prompts, and Enterprise is priced through sales.
