About Grammarly
Grammarly is one of the most widely used AI writing assistants in the world, trusted by millions of writers, students, professionals, and teams to improve clarity, correctness, and communication effectiveness.

At its core, Grammarly analyses your writing in real time and provides suggestions for grammar, punctuation, spelling, and sentence structure. But the real strength of the tool comes from its advanced AI engine, which interprets context and meaning to deliver writing improvements that go far beyond surface-level corrections. It can clarify complicated sentences, strengthen your tone, rewrite weak phrasing, and help your message sound more professional or more friendly depending on your goal.
The platform integrates seamlessly with your daily communication workflow. Grammarly works across email clients like Gmail and Outlook, collaboration tools like Google Docs and Notion, messaging apps like Slack, and even social media platforms. Its browser extension and desktop app ensure that high-quality writing follows you everywhere.
Grammarly also offers a powerful premium tier that includes full-sentence rewrites, tone transformations, formality adjustments, plagiarism detection, and AI-powered content creation. With GrammarlyGO, the tool adds generative AI capabilities that help you draft emails, rewrite large paragraphs, create outlines, and speed up everyday writing tasks.
