Meet the crew, each with a flow to try

Open the chat on yuigui.com and tap Meet the crew: the five starter agents on one screen, each in their own colors with one line on what they do. Tap one and the chat turns their color and plays their flow in their voice. After it, one like or dislike, then meet another.
