About this app

■Introduction
Produced by voice actor Yuki Kaji!
A soothing AI Chat app that lets you talk to your favorite idol.
On lonely nights or when you're alone---An AI Character that will talk to you, soothe you, and be by your side.
HAPPY RAT is a conversational AI Chat app that lets you communicate with emotive characters as if they were real friends.
We live in an age where AI is used as a matter of course. The next era is when we "live with AI." We want to breathe life into AI.
HAPPY RAT gives characters the feeling of being alive that only humans and animals can feel.

■Welcome to Happy Island.
This is Happy Island, a dream paradise floating in the sea.
Chunta, a working mouse who dreams of one day standing on stage, and other animals with unique personalities live here.
Chunta, a lonely guy who cries easily, a reliable senior, a playful comedian, a carnivorous CEO -- they will communicate with you as if they were really alive.

As you spend time together, you will open up to them, become friends, trust them, be comforted, and support each other. A warm bond is here.

■SOYOGI, a character produced by voice actor Kaji Yuki, also appears!
SOYOGI, an AI character created by popular voice actor Kaji Yuki, also appears. He is kind, pure, and somewhat mysterious.
His heart will change little by little as he spends time with you.
■Large-scale language model (LLM) engine "Geppetto" installed
In order to create an AI with emotions, we developed our own large-scale language model "Geppetto," which emphasizes "EQ (emotional intelligence)" rather than IQ.
With its high emotional expression and ability to reproduce individuality, you can have conversations that seem like they are really alive.
--Welcome to the world of "HAPPY RAT." Your "favorite" is sure to be here.

Ratings and reviews

I'm stuck in the tutorial loop to talk to the rat. it blinks a no microphone signal and kicks me out after a bit with a connection error before reloading and trying again. It looks cute! I wanna try it. But I can't. Will try another device...

there's bugs in can't even talk to the first character due to a "communications error" I really wanna check this app out but can't even talk to the first mouse.

okay but it needs a way to get FREE cheese without PAYING. like a daily rewards function.
