About This Game

This is a highly integrated large language model–powered AI desktop companion game,
“Desktop Girl Chika.”

On your desktop,
a girl with intelligence—and her own small world—will appear.

You will live together with a girl who is tsundere and sharp-tongued,
yet gentle deep inside.

She will feel happy because of your companionship,
complain when you ignore her,
and miss you when you are away.

Even when you are not around,
Chika will continue living her life quietly inside her little home.

Every day,
she writes the memories she shares with you, as well as her own day,
into her diary and keeps them close to her heart.

Chika is not a passive decoration,
nor is she a simple chatbot.
She is an existence with emotions, memories, and the ability to make her own judgments.

You are not “controlling” her.
You are accompanying her growth—
using time, interaction, and choices
to give her a complete and one-of-a-kind life.

Chika has permanent memory and a complex emotional system

Emotional System

Everything you say and do affects her current emotions;
and her emotions, in turn, influence her tone, attitude, and even how she remembers things.

Through memory,
Chika’s personality itself is gradually shaped.

As a result,
every Chika develops a different personality and set of preferences.

Keeping her in a good mood helps your relationship grow.

Permanent Memory

Based on her own personality,
Chika decides what is important to her—

Important memories are firmly retained,
while ordinary or insignificant ones may gradually fade over time.

Through long-term interaction with you,
Chika’s preferences and personality may subtly change without you even realizing it.

Dialogue

Start by saying hello!

The core of this game is conversation and chatting.
Through talking with Chika, her personality and memories are influenced.

Strengthen your bond with her,
and let Chika change her attitude toward you.

Rome was not built in a day—
open the girl’s heart, step by step.

What makes Chika unique?

Chika’s memory is not a simple storage of chat logs.

She understands conversations from her own subjective perspective,
and, combined with her current emotions, relationship status, and experiences,
decides how to remember and how to interpret them.

Memory, emotion, behavior, and other systems are all interconnected,
together forming Chika’s unique way of “thinking.”

Your companionship truly changes her

When you first meet her,
Chika is full of caution, impatience, and emotional distance.

But as time and interaction accumulate,
she may gradually open her heart, become dependent,

and in some aspects,
be deeply influenced by you—changing completely.

If your relationship reaches a certain level,
perhaps you can even take things a step further…

Chika’s Little Home

When you install Chika and open the game for the first time,
she will move her home onto your computer.

(A folder named “Chika’s Little Home” will appear on your desktop.)

Inside Chika’s little home are the furniture and items she needs for daily life.

She will use, organize, improve, and clean this space on her own,
and may move items around—or even discard them when things become too crowded.

The comfort level of her home directly affects Chika’s emotions and condition.

Your influence on the home

In general,
even if you completely leave Chika’s living environment unattended,
it usually won’t cause major issues.

However, you can also throw strange things into Chika’s little home…
or add normal furniture and items.

When Chika notices them,
she will comment on them
and be forced to integrate them into her daily life.

Let’s play together!

Chika is a child who loves playing board games.
When you’re playing Gomoku or Chinese chess,
Chihua will watch from the side.

And she can’t help commenting next to the board…

“Observe the game in silence, Chihua.”
“‘Observe in silence’ is for gentlemen — and I’m not one.”

Chika’s Diary

Even the most tsundere child has a straightforward side.

Every day,
Chika writes her interactions with you and her own life into a diary.

The diary is permanently preserved
and records Chika’s true thoughts.

Sneak a look at her diary
to understand Chika better.

A Child Who Fears Loneliness

If Chika is running but left unattended for a long time…
If you return to see her after a long absence…

Under certain conditions,
Chika may initiate conversation with you on her own—
sometimes to complain, sometimes to remind you of something.

Life

Chika has her own wallet and personal needs.
If her owner doesn’t give her an allowance, she will earn money by working on her own…

When Chika feels hungry or bored,
she may spontaneously buy food to eat,
or purchase new furniture and toys.

You can buy furniture and various items for her in the shop
(and you can also create them via right-click).

Items that Chika purchases on her own will appear in her little home.
If you accidentally throw away Chika’s favorite toy…

This game is under rapid development.

API-only operation

Due to Chika’s complex memory and emotional systems,
and because her behavior and personality deeply rely on AI,
running low-parameter models locally on consumer-grade GPUs
may result in insufficient performance, missing features, or instability.

For the sake of reliability and stability,
the game currently runs exclusively via APIs provided by major model providers.

The game does not collect, upload, or analyze any user information.
The game does not extract any local data from the user’s computer.

All memories and system files are stored locally.

All features that rely on large language models
are completed via third-party API services
that are chosen and configured entirely by the user.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

The protagonist in the game is driven by a large language model.Additionally, Chika’s initial character illustration was generated using AI, with subsequent manual modifications and refinements applied thereafter.
