An Alexa custom skill is a skill which can be enabled by people on their Alexa devices. These skills can have custom functionality (we call them skillets), which provide a wide variety of interactions. Functionality (skillets) can provide a way to add someone to a mailing list. They can also give specific facts about an asked about topic or give random phrases. You can create a game. There are so many possibilities. Feel free to chat about tis with us, we love talking about new skill creation ideas.
