Alexa Skills can give users access to accounts they've already set-up, such as the Alexa Skill for SiriusXM radio, ESPN, or even their car insurance if they have Alliance Insurance. With Alexa connected to these accounts, people can pull up details and content through their Alexa-enabled device. For example, the Alexa Skill for Major League Baseball lets Alexa users stay current with baseball stats and hear shows. Use the Alexa Skill for Fandango to not just find a movie but buy a ticket.
Alexa Skills themselves are quite helpful. However, even with an updated Skills section in the Alexa app and the ability to add skills using only your voice, discovering new and useful skills is a less than desirable experience. So much so that Amazon actually created a skill called Skill Finder which, you guessed it, helps you discover new skills. Launch it by saying, "Alexa, open Skill Finder" or "Alexa, tell Skill Finder to give me the skill of the day."
