Elon Musk Teases Grok Plugins for Microsoft Excel, Word, PowerPoint With xAI Demo: Here's What Grok Can Do For You

Elon Musk teased upcoming Grok plugins for Microsoft Excel, Word and PowerPoint after an xAI demo showed Grok 4.3 converting a dense neuroscience paper into a nine‑slide deck, highlighting potential productivity gains from automating document summarization and slide creation. The story notes Microsoft already embeds AI across Office via Microsoft 365 Copilot (paid with limited free rollouts through 2025–2026), suggesting Grok integration could further bolster Office productivity and user demand. Microsoft shares showed modest movement around the news—closing $422.79 (up 0.60% on Friday) and trading $422.34 (‑0.11%) in after‑hours—underscoring limited immediate market reaction but reinforcing the narrative of AI as a growth catalyst for MSFT. Overall, the article frames the development as supportive for Microsoft’s AI positioning and investor interest in Copilot/Office monetization.
