New in Copilot Cowork: mobile, skills, and plugins.

Now available on iOS and Android, so you can delegate work from your phone, pick it back up on your desktop, and keep tasks moving without breaking flow.

And with new connectors, Cowork can operate across business systems and data.

In the last month, people have been using Copilot Cowork to do amazing things – from building inbox workflows to sales campaigns. And I’m excited to share three big updates to help you accomplish even more: 1) mobile on iOS and Android so you can delegate work from anywhere, 2) skills to help you reuse and scale how work is done and 3) new plugins + connectors to bring your data into the flow of work.

I’ve been testing these updates out – here’s a quick demo of how I’ve been using mobile in my daily work.
