Seriously? Sekai is the AI app that to my knowledge was the first AI chatting app I used which actually featured dynamic character photos which changed based on their emotions (happy, sad, angry) and different character images would show up depending on who was speaking. If you didn’t see Sekai then where did you get the idea for the dynamic character images that change based on emotions? If the answer is visual novels then okay I guess, but I think Sekai is one of the ones that popularized it (at least for me). The Visual Novel mode in FurAI reminds me a lot of Sekai, I haven’t used it in a long time but I got nostalgia from it.
