What is Grok by SpaceXAI for Word?

Grok by SpaceXAI for Word is a Microsoft 365 add-in that places an AI agent directly inside your Word documents. Instead of switching between tabs or copying text into external tools, you work with a conversation-based sidebar that can search the web, rewrite paragraphs, summarize reports, generate outlines, create tables, and execute edits — all within the document you're editing. Every change lands as a visible revision you can keep or undo.

Who it's for

• Writers and editors who need to tighten phrasing, fix grammar, or simplify language without leaving their document.
• Project leads and managers who want to normalize inconsistent formatting, heading styles, and terminology across documents that have passed through many hands.
• Busy professionals who need to turn rough notes into structured drafts with real Word headings and lists, then iterate in the same conversation thread.

Key features

Edits you can undo

Every grammar fix, phrasing improvement, or simplification lands as a visible revision with a before-and-after view. You keep full control — accept or reject each change individually, without merging text from a separate copy.

Structure rough notes

Give Grok your rough notes and specify the format you want. It writes a structured version straight into the document using real Word headings and lists. You can iterate in the same thread, and everything stays editable.

Keep it consistent

Documents drift as they pass through many hands. Grok normalizes heading case and styles, aligns terminology in one pass, and reports every change back to you — no need to re-read every page.

What stands out

Grok works beside your document, not in a separate tab — every edit lands where it belongs.

The add-in sits as a panel docked to the side of your Word window, not as another browser tab or external tool. It reads what you point it at and executes changes directly in the file. This means you can ask for a rewrite, see the result in place, and decide to keep or undo it — all without breaking your workflow.

Worth checking out if…

You regularly edit, restructure, or polish documents in Word and want an AI agent that works inside the file rather than requiring copy-paste. It's especially useful if you manage documents that accumulate inconsistencies across contributors, or if you prefer to iterate on drafts through conversation instead of manual formatting. Grok is also available for Excel and PowerPoint, so it fits into a broader Microsoft 365 workflow.
