Grammarly

The tool provides AI‑driven writing assistance that can be used within any application or website. It offers real‑time suggestions for grammar, spelling, punctuation, style, and tone, allowing users to keep their personal voice while making the text clearer and more concise. It also includes a text‑generation feature that can produce content based on a range of prompts.

Typical users include individuals and teams who need to produce professional‑sounding documents, emails, messages, or proposals quickly. The service is adopted by a large number of organizations and millions of people, and it is positioned for both personal use (free tier) and paid plans for enhanced capabilities such as expanded prompt libraries and team collaboration.

Distinctive aspects highlighted are the focus on responsible AI—user content is not sold or used for advertising—and a suite of security accreditations. The product emphasizes tone‑aware suggestions that can align writing with brand guidelines, and it provides a “read‑through” view that simulates how an audience will perceive the text.
