Copilot Cowork: Microsoft’s New AI Tool for Managing Workflows

Microsoft has introduced Copilot Cowork, a new AI capability built on Anthropic’s Claude model, as part of its Microsoft 365 Copilot suite, making it available to customers through its Frontier program alongside updates to its Researcher tool.

Copilot Cowork is designed to handle complex, multi-step work inside Microsoft 365. Instead of generating isolated responses, the system can plan tasks, coordinate across tools and files, and execute workflows with ongoing progress visibility. Microsoft said the feature has already been tested with select customers, including Capital Group, where it has been used for tasks such as planning, scheduling, and preparing materials for executive reviews.

“This isn’t about generating content or answers. It’s about taking real action – connecting steps, coordinating tasks and following through across everyday workflows,” said Barton Warner, senior vice president of enterprise technology at Capital Group. He added that operating within enterprise data and security boundaries allows teams to “experiment, learn and scale with confidence.”

The release is part of what Microsoft calls “Wave 3” of Microsoft 365 Copilot, reflecting a broader push to embed AI deeper into everyday workplace tools. According to the company, Copilot Cowork can manage both one-off tasks and recurring processes, such as monthly reporting, by combining capabilities from Microsoft and third-party models.

Alongside Cowork, Microsoft introduced upgrades to its Researcher feature, which uses multiple AI models to analyze information and generate detailed reports. A new “Critique” function separates drafting and review into two stages, with one model producing an initial output and another refining it as an expert reviewer. The company said these changes improved performance on its DRACO benchmark for research quality by 13.8%.

Microsoft also added a “model Council” feature that allows users to compare outputs from different AI systems side by side, highlighting differences in reasoning or conclusions.

“All of this innovation is part of Wave 3 of Microsoft 365 Copilot, which marks a turning point in how AI shows up at work,” said Jared Spataro, chief marketing officer for AI at work at Microsoft. “When intelligence and trust move together, AI stops being an experiment and starts becoming how work gets done.”

The updates reflect Microsoft’s broader strategy of combining multiple AI models within its software ecosystem, positioning Copilot as a central layer for executing tasks, analyzing information, and coordinating workflows across enterprise environments.
