Reach 145 million monthly users with the Cortana Skills Kit


Create a new Cortana skill and let users engage with your software more naturally. Start with existing code to build skills that work across Windows 10, Android, and iOS as well as standalone devices based on the Cortana Devices SDK.

Leverage your existing investments

We’ve made it easy to get started. Use the code you’ve already developed for Alexa, the Microsoft Bot Framework, or Cortana VCD as the basis for your new Cortana skill.

Build once, engage everywhere

Cortana skills aren’t tethered to one platform or device—they work across Windows 10, Android, and iOS so you can reach 145 million monthly users.
