What is Grammarly AI?

Grammarly is a writing assistant that checks your work in real time as you type. It catches grammar, punctuation, and spelling errors, then suggests improvements to clarity and tone. The tool works across emails, documents, social media posts, and web forms, making it useful for anyone who writes regularly. Beyond basic corrections, Grammarly analyses your writing style and can flag issues like repetitive phrasing or inconsistent tone. A plagiarism detector is included to check whether content matches existing sources online. The free version covers essential grammar and spelling checks, whilst paid plans add more advanced features like tone detection and brand voice customisation.
