One sentence becomes a world and a cast with minds of their own. The story remembers everything you do.

The Inn at MidnightLIVE
Mei · Innkeeper
The inn smells of cold tea and damp wool. Mei sets down her ledger, looks at you. “You’re late.”

“Sorry. The river was higher than I expected.”
Mei · Innkeeper
Her brow tightens, then softens. “You said that last time.” She slides a bowl of hot tea across the counter.
Mei remembers what you said on turn 87

She has been waiting. You are not as forgotten as you hoped.

How it works

Three steps. One life.

You write a single line. KIEIO builds a world from it. Characters arrive with memory, opinions, and plans of their own.

1

Write a seed

A line, a paragraph, a premise. Write as much or as little as you like; the AI builds from here.

Your input
An inn at midnight. The keeper studies a stranger who arrived too late.
2

Enter the world

KIEIO sets the scene, fills it with people, and hands you the protagonist. The narrator listens before it speaks.

World generated
The inn smells of cold tea and damp wool. Mei sets down her ledger. The rain has not let up in three days. “You’re late,” she says. She does not ask your name.
3

Live a life

Speak, act, choose. Every consequence carries weight, and the world bends around what you have done.

Your move
“I’m sorry. The river was higher than I expected.”
Sit down without answering. Let the silence speak.
“Do you remember me, Mei?”
Memory system

NPCs remember.

Not just the last three messages. Four layers of memory hold what you did, who you hurt, who you loved. Two hundred turns later, it is all still there.

Emotional memory

How they feel

Trust, suspicion, affection, grudges. NPCs carry their feelings forward and can hold a grudge for two hundred turns. Forgiving you is their decision, not yours.

“You said that last time.” She slides the tea across, but does not look at you.Turn 247 · Mei’s trust in you: low
Recent memory

What just happened

The latest exchanges, tone, and mood. “Mei looks at you” needs no footnote about who Mei is.

World knowledge

Who is who

Names, relationships, the shape of the world. Mei keeps the inn, the river floods every spring, and you are a courier who lost something.

Living lorebook

What the world knows

Every character, place, and promise, organised automatically into a living lorebook. It finds “the person you owed last spring” even if you never said the name.

200+
turns later, still remembered

Every NPC has a hidden mind.

Ordinary NPCs answer you. KIEIO’s NPCs think: every turn, each character on stage runs their own inner monologue. What they hide, what they plan, how they really feel, and the story follows their secrets.

Paid plans: Standard thinks with 1 NPC per turn, Pro up to 3
Mei · Innkeeper

Outwardly: Pours your tea.
Inwardly: Counts how many times this stranger has shown up late. Three now. The favour is becoming a debt.

Old Wei · Bandit

Outwardly: Laughs at your joke.
Inwardly: Wonders if you noticed his hand drifting toward the knife. Decides: not yet. The boss said wait.

Lin · Magistrate’s daughter

Outwardly: Corrects your accent.
Inwardly: Hopes you keep talking. Her father would never let her marry a courier. She knows. She slows down anyway.

Every story builds its own interface.

A romance shows moods and relationships. An adventure shows health, stats and a backpack. A sports story shows stamina and box scores. The AI designs each story’s panel the moment you create it.
