Microsoft (MSFT) is bringing Anthropic's (ANTH. PVT) Claude Cowork to its Microsoft 365 Copilot AI platform. Called Copilot Cowork, the service, which Microsoft said it developed in close collaboration with Anthropic, can perform tasks on behalf of enterprise users, such as building presentations, pulling data into Excel spreadsheets, and emailing co-workers to set up meetings.

The stakes are high for Microsoft because Copilot is core to a push by Chief Executive Satya Nadella to transform Microsoft into an AI-first company, much as he transformed it into a cloud-first company around a decade ago.
