Copilot Cowork lands on iOS and Android — Microsoft puts agents in your pocket
Mobile launch on May 5 is the moment Copilot stops being a sidebar and starts being a workflow you can delegate to from a phone.
Microsoft on Tuesday brought Copilot Cowork to iOS and Android, ending the era in which the most ambitious Copilot features lived on a desktop browser tab. Mobile workers — anyone who spends large parts of the day between meetings, in transit, or on a phone — can now hand Copilot a task from their device and let it run while they do something else.
That single sentence is the entire pitch. Cowork is not, on the May 5 release, a new model or a new feature surface. It is the existing Copilot Cowork system, rebuilt to delegate work in the background while the user moves on. The mobile app lets you start a task, lock your phone, walk into a meeting, and come back to a finished outcome rather than a chat thread waiting for your next reply.
The release pairs with Microsoft’s broader agent-first strategy, also announced May 5, that positions Copilot as the orchestration layer for autonomous agents inside Microsoft 365. The Frontier program — Microsoft’s tier of customers running the most aggressive Copilot deployments — gets reusable Cowork Skills and a new plugin model that lets enterprise teams build agent skills once and reuse them across deployments.
Charles Lamanna, the Microsoft corporate vice president running this part of the suite, framed the system architecture in the launch communications: “once AI understands your work, it can start contributing to it and working alongside you.” The system that does the understanding is Microsoft’s Work IQ layer, which sits underneath Cowork and provides the model with grounded knowledge of an organization’s data, tools, and processes.
Cowork’s connector list now reaches SharePoint, Outlook, Teams, OneDrive, Dynamics 365, and a growing set of third-party SaaS systems. For mid-market customers, the practical change is the cadence: you can hand the system a research task at 9 a.m., go run your day, and come back to it in the afternoon. For IT, the harder question is the device-management model — what governance Cowork on a personal phone needs that it didn’t need on a managed laptop. Microsoft has not yet released its full mobile enterprise-controls guidance.
