Interactive stories
Multi-day story arcs delivered a little at a time, with scenes, reveals and moments that wait for your reply before the plot moves on.
Independent interactive studio
Stories that write back.
Kagi Studios designs interactive narrative experiences. Our characters remember you, our stories unfold over days, and every experience is written, directed and run by a small team that answers its own mail.

About
A small studio with one idea: a story is better when it pays attention to you.
Kagi Studios builds interactive stories. We combine writing, character design and software engineering so that a story can respond to the person experiencing it: it remembers what you said, keeps its own schedule, and moves forward at a human pace.
We are intentionally small. That keeps the writing coherent, the quality high and the people who make the work close to the people who play it.
Our name
鍵 Kagi means key.
It is the small detail that opens a story up: the line a character remembers, the reveal that lands on the right day, the moment a player realises the story was paying attention.
The fox is our companion: curious, quiet, and always one step ahead of the plot.
What we make
Narrative experiences built around conversation.
Characters with memory
Each character has a defined personality, voice and history, and remembers the details you share, so the tenth conversation feels different from the first.
A familiar way to play
Our experiences live in a phone-style web app and a messaging companion. There is nothing to install and nothing to learn.
The experience
A story that lives in your pocket.
- Opens like an app you already know. A phone-style interface with messages, stories and a small shop for in-story items.
- Moves at human speed. Characters reply when it makes sense for them, not instantly, so the story has room to breathe.
- Remembers you. Names, details and past conversations carry forward from one day to the next.
Services
We build for others, too.

Tell us about itHow we work
Written by people, run with care.
-
Write
Every character starts as a written canon: who they are, how they speak, what they will and will not do. Our writers own it.
-
Build
We use modern AI language models to give characters natural, in-the-moment replies, always inside the boundaries the writers set.
-
Test
Before a character update goes live it is checked against an internal set of scenarios, including safety cases, and ships only when it passes.
-
Look after it
We monitor each experience after launch, read player feedback, and fix problems quickly.
A story over days
Pacing is part of the craft.
Our stories are not binge-able on purpose. They unfold across days, so there is time to think about what happened and look forward to what comes next.
- Day one
A first hello
You meet the story and the people in it.
- The first days
Getting to know each other
Characters learn your preferences and start to remember.
- Midweek
Turning points
Events happen on the story’s schedule, not yours.
- And onward
The story continues
The story carries on well beyond the first week.
Principles
What you can expect from us.
Honest about AI
Our characters are AI-driven, and they say so if you sincerely ask.
Private by default
We keep only what an experience needs. We do not sell player data or use it for advertising, and our apps contain no third-party trackers.
Your data is yours
Players can export everything we hold about them, or delete it, from inside the app.
Clear prices
You see what something costs before you buy it, and billing questions are answered by a real person.
Every story begins with a key.
