Our latest Conversational AI tutorial "Alexa Messenger" is out: Alexa Messenger
You will learn how to integrate our native mobile app development tools with our Alexa skill development tools to create a 2-way messaging system between a mobile app and an Alexa device.
I have the same problem. When I go to test the skill it wants me to log in but I was told that we don't need a developer account to run the program for the Alexa AI.
Please make sure that you log in via https://hourofai.appinventor.mit.edu/ if you wish to use an automatically generated account. If not, then you'll need to authenticate with your own Amazon Developer account (e.g., if you'd like to try things out with your own Alexa device).
