Earlier this year, Amazon introduced “Alexa Blueprints” – a way for anyone to create their own customized Alexa skills for personal use, without needing to know how to code. Today, the company will allow those skills to be shared with others, including through text messages, email, messaging apps like WhatsApp, or social media platforms like Facebook, Twitter, and Pinterest.

The idea is that you could create a skill for your friends or family to use, to save them the work of having to edit Amazon’s provided templates with your own content. Amazon suggests the new sharing feature could be used among study groups, who have built a custom “flashcards” skill, for example, or shared among family for a birthday. (Presumably, the skill is part of your present?)
