About AI
AI is used in the making of Idealium.
What it generates, though, is never used as it is.
The question of how to handle AI is the same question Idealium asks.
Design
Everything below forms the foundation of the work, and all of it is drawn by human hands.
- Character design
- Event CG
- Main character portraits and sprites (including expression and pose variants)
*Generated images are sometimes referenced while an idea is taking shape, but nothing is traced. Everything is drawn by human hands.
For the items below, some images generated with Gemini are used as source material, after being reworked by hand.
- NPC sprites
- Map tiles
- Skill and item icons

The image has no transparency, and yet it draws in the checkerboard pattern as well.

Text
Claude is sometimes used to generate scenario, dialogue, text, and translation.
Text that goes into the game is checked and reworked by a human before it finally reaches the player.
Music
For some tracks, Suno is used while working out the structure of the song.
The generated audio is not used as it is, and the performance and sound design are done by human hands.
Programming
Claude Code is used as part of the development process.
Generated code is adopted only after a human has checked how it runs and how it is designed.
Student
Senpai, is this what the first day is like?
Isn't everyone way too quiet?
I'm the only one talking here.
Student
Senpai, listen to this.
I peeked at every notebook around me,
and every one of them was blank.
Student
Senpai, I raised my hand.
I've never once done that before.
...Why did I do that, I wonder.
Student
Senpai, I solved it.
...Nobody was watching, though.
Can you watch me do one more?
Student
...How many did I get again?
I wasn't counting.
I should have counted properly.
Student
My share is one short.
They got swapped somewhere, didn't they.
Give it back.
