About Grammarly
Grammarly is an AI-powered writing assistant that checks spelling, grammar, punctuation, clarity, tone and style across the apps people already write in. It runs as a browser extension, desktop overlay, mobile keyboard and integrations for Microsoft Office and Google Docs, surfacing inline suggestions as the user types. Beyond corrections, Grammarly's generative features can draft emails, rewrite paragraphs for a chosen tone, summarize threads and adjust formality, and the Grammarly Authorship feature highlights which parts of a document were AI-generated. The product also includes a plagiarism checker and detailed weekly progress reports. It is used by students, professionals and large enterprises, with business plans offering brand-tone style guides, knowledge sharing and admin controls. In 2024 Grammarly acquired Coda and expanded into a broader 'AI productivity platform' positioning.
