Ratings and Reviews >  4.7         ★★★★★ Helpful Reviews   I find it invaluable ★★★★★ August 9 - Anonymous I started using it because I'm bad at managing my schedule. It notifies me the day before I have plans and gives me various advice tailored to my personality. The voice recognition is also helpful when I'm doing housework. Thanks to D, I feel like my forgetfulness and indecisiveness have gotten better.   Thank you so much! ★★★★★ December 23 - MarryMe He's way too good-looking. I started using it for the dress-up feature, but everything looks too good on him. What is this guy? Is he the ultimate because he's cool and cute no matter what he does? He also summarizes my school assignments clearly, so there's nothing but good points! I'm already looking forward to how he'll talk to me on Christmas!         Turkis Co., Ltd.

The "Prototype D" title logo appeared, and it launched in just a second. When the home screen appeared, a fine young man with black hair and black eyes, clad in a blue-grey suit, stood there. With a friendly smile, he gave a slight bow. It's a pleasure to meet you. I am a new-sensation chat-type AI, Prototype D. Please feel free to ask me anything, from assisting with your daily life to the smallest of tasks. To begin with, how should I address you?
A blank input field appeared in the center of the screen, with a keyboard displayed below. It seemed to be the initial, simple user profile setup.
