Microsoft Launches Agent Mode in Office Applications

Apr 23, 2026

Microsoft is rolling out Agent Mode in Word, Excel, and PowerPoint this week, representing a significant upgrade to its AI-powered productivity tools. Corporate vice president Sumit Chauhan explains that Agent Mode, which Microsoft calls 'vibe working,' is a more powerful version of the Copilot experience the company has been marketing to businesses. Unlike earlier Copilot versions that functioned as passive partners capable only of answering questions, Agent Mode can take direct action on document canvases—a capability that wasn't possible when Microsoft first shipped Copilot because foundation models lacked sufficient power. The rollout marks Microsoft's push to deliver more autonomous AI assistance in its core Office applications.
