Microsoft is bringing “vibe working” to Word, Excel, and Copilot with new Agent Mode

Microsoft is launching “vibe working” in Microsoft 365 Copilot, introducing Agent Mode in Office apps and Office Agent in Copilot chat. This update brings advanced reasoning models and generative AI to Excel, Word, and PowerPoint, building on methods that have accelerated software development and now targeting productivity in Office workflows.

By leveraging OpenAI’s latest models, Agent Mode orchestrates multi-step tasks and enhances productivity. Users can start with a simple prompt and interact with Copilot through iterative workflows, guiding the AI as it generates and refines Office artifacts, such as documents, spreadsheets, and presentations.

Focusing on Excel and Word, Agent Mode in Copilot lets users interact conversationally with spreadsheets, using Excel artifact understanding to support complex modeling, output evaluation, and continuous result improvement. In Word, Agent Mode enables “vibe writing”, where Copilot drafts content, suggests enhancements, and requests clarification, turning document creation into a dynamic dialogue.

For PowerPoint and Word creation, Office Agent in Copilot offers a chat-first interface, powered by Anthropic models, that produces polished presentations and well-researched documents. These new capabilities are available today to Microsoft 365 Copilot licensed customers as part of the Frontier program, and to Microsoft 365 Personal or Family subscribers in the United States.
