Microsoft Announces Claude-Powered Copilot Cowork Agent to Automate Workplace Tasks

Microsoft has introduced a new AI agent called Copilot Cowork as part of the next phase of Microsoft 365 Copilot, hinting at a broarder shift toward task-oriented “agentic” AI inside workplace tools. The announcement comes as Microsoft rolls out what it describes as Wave 3 of Microsoft 365 Copilot, where the AI assistant evolves beyond simple prompts into systems capable of handling complex workflows. Copilot Cowork is currently available in private preview for select customers, with a wider research preview expected later this month through Microsoft’s Frontier program.

Microsoft brings Claude-powered Cowork agent to Copilot

The new agent was developed in collaboration with AI company Anthropic, integrating technology behind Claude Cowork directly into Microsoft 365 Copilot. Microsoft has already added Anthropic’s Claude Sonnet 4 and Claude Opus 4.1 models to the Copilot ecosystem, and the new agent builds on that multi-model approach.

According to Microsoft, Copilot Cowork is designed to handle long-running, multi-step tasks across different applications. For example, the agent can prepare for a customer meeting by building a presentation, gathering financial data, coordinating schedules, and notifying team members while keeping the user informed throughout the process.

The tool can also assist with research workflows. In one example, Cowork gathers earnings reports, SEC filings, analyst commentary, and relevant news to generate an executive summary, structured research memo, and Excel workbook with organized data.

Microsoft expands its agentic AI ecosystem

Besides Copilot Cowork, Microsoft also plans to introduce agentic AI features across Word, Excel, PowerPoint, and Outlook. These updates will allow users to create documents, analyze data, and build custom AI agents directly inside Microsoft 365 apps. The company also confirmed that Microsoft Agent 365, a platform designed to help organizations manage AI agents, will become generally available on May 1. Microsoft plans to price the service at $15 per user.
