About Grammarly

Grammarly is an AI-powered writing assistant available as a desktop app, mobile app, and browser extension, with integrations for Windows, Mac, Chrome, Safari, Firefox, Edge, Microsoft Office, and Google Docs. It provides grammar and proofreading corrections, tone suggestions, full-sentence rewrites, plagiarism checking, and AI-generated text detection, along with agents for humanizing writing and analyzing reader reactions to a piece of text.

The product serves individuals, teams and businesses, and educational institutions, with functions tailored to customer support, marketing, IT, sales, and HR use cases. It offers a free tier with mistake-checking and 100 AI prompts, a Pro tier at $12 USD/member/month (billed annually, $30 billed monthly) that adds full-sentence rewrites, tone adjustment, brand-style consistency, and 2,000 AI prompts, and an Enterprise tier with unlimited members, dedicated support, confidential mode, granular roles and permissions, data loss prevention, and unlimited AI prompts.

Grammarly states it does not sell or monetize user content, does not use it for advertising, and does not allow third-party service providers to train models on user content. The company is now part of Superhuman, which offers additional productivity apps and agents alongside Grammarly's writing tools.
