Grammarly Description:

Grammarly is a comprehensive AI-powered writing assistant designed to help users write with clarity, precision, and confidence. Launched in July 2009 by Ukrainian founders Alex Shevchenko, Max Lytvyn, and Dmytro Lider, Grammarly has evolved from a basic grammar-checking tool into a sophisticated platform that supports grammar, spelling, punctuation, style, tone, and plagiarism detection across web, desktop, and mobile environments

Over the years, Grammarly has introduced features that go beyond grammar correction. Users benefit from real-time suggestions on clarity, tone, and style, plus a plagiarism checker that flags unoriginal content. With support across browsers, desktop apps, Microsoft Office, Google Docs, mobile keyboards, and more, Grammarly ensures seamless writing assistance wherever you type

GrammarlyGO, introduced in 2023, adds generative AI capabilities—enabling users to generate, rewrite, and ideate content based on prompts—making Grammarly not just a checker, but a creative writing partner

In 2024, Grammarly launched Authorship, a tool designed for transparency in the AI age. It identifies which parts of a document are typed, copied, or AI-generated, fostering trust and integrity in writing

Choosing a freemium business model in 2015 dramatically accelerated growth, broadening accessibility to basic features while keeping advanced tools behind a subscription tier  Grammarly’s mission—“improving lives by improving communication”—has guided its steady expansion into a global writing assistant used by millions worldwide
