Overview / Description
Grok by SpaceXAI for Word is an AI writing assistant add-in that docks Grok inside Microsoft Word so you can draft, restructure, and tighten wording without leaving the document. It runs as a conversation-based agent panel beside your page, where you can ask it to rewrite paragraphs, summarize long reports, improve clarity and tone, generate outlines, create tables, or expand ideas in place. Built by xAI, the add-in emphasizes real-time web access and on-the-fly diagramming, which distinguishes it from Microsoft's built-in Copilot, and it includes governance features aimed at enterprise security and compliance. As an AI writing assistant for Word, it suits professionals, analysts, and teams who draft documents directly in Microsoft 365. It installs in one click from the Microsoft add-in store, and admins can deploy it across an organization. The Word add-in is available to xAI's SuperGrok, Heavy, Business, and Enterprise plans rather than as a standalone purchase.
