The Ninety-Second Vault
The museum vault opens for ninety seconds at midnight. Your inside man just stopped answering.
The interactive AI story where you choose what happens next
The branching paperbacks you grew up with had three endings, and somebody else wrote all of them. Runebook is different: an AI Storyteller carries the story forward around what you actually choose, and you can type anything, not just pick A, B, or C.
The story is not just written. It is played.

Stories you can step into
Every one of these is a story you can start today. Pick one, or describe the story you want in any setting, and the world is built around it.
The Expedition That Wrote Back
Six explorers went into the ice and sent back one journal. The map in it doesn't match the mountains.
An Empty Throne by Morning
The crown has no heir, the court has three, and you hold the only signed will. Both armies know it.
The Longest Night of Your Life
The festival ends in fire at midnight. You alone wake up on the morning it starts — again.
The Monster That Saved You
The creature terrorizing the valley once pulled you from a river. The mob at your door wants you to lead them to it.
A Seat Beside Your Enemy
Your family's name is one scandal from ruin. Tonight's seating chart puts you next to the man spreading it.
Planted Evidence
They found the stolen artifact in your rooms. You have until the trial to find out who put it there.
The Tower Takes Everyone
The one man who can clear your name is locked in the tower prison. As of tonight, so are you, on purpose.
Heist, throne, time loop, trial: these aren't separate apps. They're one Storyteller that can run any of them, and new ready-to-play stories are being added.
Choices that compound
Every scene ends with the same question: what do you do? Tap one of the Storyteller's suggestions, tense and pointed at trouble, or ignore them all and type your own move. Say it out loud if your hands are full. The story bends around whatever you actually do.
And here's the part the old paperbacks could never print: your choices don't evaporate when the scene ends. Spare the informant, insult the duchess, pocket the letter you were told to burn, and the world keeps the receipt.
One scene later, those are choices. Ten scenes later, they are history.
That history is what the ending is made of. Your story rises toward a real finale: not one of three printed on the last page, but the one your choices shaped, scene by scene, the whole way down. Drama is what changes because you said it.
How it works
Say what story you want
A heist in a city of canals. A time loop at your own wedding. A throne nobody should sit on. Describe it, and the Storyteller builds the world, the people, and the trouble.
Choose, type, or say what you do
Tap a choice when it nails what you wanted, or type anything at all: accuse the wrong person, kiss the right one, climb out the window mid-interrogation. At pivotal moments, fate gets a say.
The story remembers
Nothing you do is disposable. The story carries it all forward: the people you've met, the promises you've made, the doors you left open, and it builds toward an ending your choices shaped.
An interactive AI story that reads like a novel
Runebook plays in your browser on phone, tablet, or desktop. No download. Open it and your story looks like a story: typeset pages, chapter headings, scene images the prose flows around.
Then it does something a book never could: it speaks. Turn on narration and hear your story told word by word, with voices for the people in the room. Your story, read aloud as you live it.
You can keep it to yourself, or bring friends into the same story and decide together. Either way, the pages are yours.
A story game where choices matter and keep mattering
Plenty of apps let you pick an option. The question is whether anyone remembers you picked it.
Runebook remembers your story. The people you've met remember what you did. The guard you bribed greets you differently than the guard you humiliated. Places change because you changed them. Promises come due. Something you did is still waiting for you.
And the world doesn't idle politely while you decide. Hesitate at the wrong moment and the trial proceeds without your evidence, the ship leaves the harbor, the rival heir gets to the general first. If it has a past, it can have a future, and your past is the plot.
AI choose your own story, including the ones nobody wrote
"Choose your own" used to mean choosing between someone else's branches. Here it means choosing the story itself.
Want a cozy mystery on a snowed-in train? A succession crisis where you're the unwanted heir? A haunting where the house remembers your family's name? Describe the story you want in any setting, any era, and start living it. There's no list you have to pick from and no branch you can fall off, because the path forward is shaped around what you do next.
Try something nobody planned for. The story still responds. That's the whole point.
From the branching paperbacks you grew up with to a story that answers anything
You remember the drill. Keep a finger wedged in page 47 as insurance. Flip ahead to see which choice gets you eaten. Reach an ending in eleven minutes and start over.
We loved those books, and we kept their best promise: you are the main character, and the story turns on what you decide. We just removed everything that was a limitation of paper. The endings aren't pre-printed. They're earned. The choices aren't a menu of two. They're anything you can type or say. And no author had to guess, years in advance, what you'd want to do on page 47. The Storyteller carries that page forward from the choice you made.
This is an interactive AI story with the Storyteller holding the pen, and you holding everything else.
Questions, answered
What is an interactive AI story?
It's an interactive story where an AI Storyteller carries each scene forward from your decisions, instead of routing you down branches an author wrote in advance. In Runebook, you say what kind of story you want: a heist, a haunting, a succession crisis, then play as the main character. Every turn you choose, type, or say what you do, and the next part of the story responds to that choice. There's no fixed path to follow and no page to flip to; the next scene changes with how you act.
Is it just multiple choice?
No. The tappable choices you see each turn are suggestions, fast ways to keep a scene moving. Typing your own move is just as central: you can attempt anything you can put into words, whether or not it was offered. You can also speak your move out loud and the Storyteller takes it from there. Most stories end up as a mix: taps when an option nails what you wanted, typed moves when you have a better idea. The story treats both the same way.
Can my choices actually change the ending?
Yes. Endings are the point, not a bonus. The alliances you formed, the secrets you exposed, the people you crossed. They shape what the final chapters can even be. By the time you reach the ending, it isn't one of several stored outcomes. It's the one your accumulated choices earned, and it wouldn't exist without them.
How is this different from the branching paperbacks I grew up with?
The books gave you real agency inside hard limits: a handful of branch points, endings printed before you ever opened the cover. Runebook keeps the second-person thrill: you are the main character, the story turns on you, and the limits are gone. Choices aren't restricted to what's listed. The story remembers what matters about what you've done, so consequences compound instead of resetting at each fork. And no two readers are ever holding the same book.
How is it different from story apps like Episode or Choices?
Those apps are menus of authored branches, well-crafted ones, but every option you'll ever see was written before you arrived, and the big choices often sit behind a paywall. Runebook is not selling premium branches as the core experience. The Storyteller responds to anything you do, including things no author anticipated, and your story builds toward an ending your choices shaped. It's the difference between picking a path through someone's story and being the reason your story goes where it goes.
Does it remember my choices between sessions?
Yes. Runebook remembers your story across sessions: the people you've met, where you stand with them, what you carry, what you promised, and what you set in motion. Come back a week later and the consequences are where you left them: the ally you saved still owes you, the lie you told is still circulating. Memory is the emotional backbone of the whole experience. The choice you made in chapter one is allowed to matter in chapter twenty.
Do I need to know anything about games to play?
No. There are no rules to learn, nothing to configure, and no manual you should have read first. If you can answer the question "what do you do?", you can play. Choose one of the offered options, or type what you'd do in plain language, or say it out loud. The Storyteller handles everything else. At pivotal moments, fate gets a say in how risky moves turn out, but you never manage that. You just live the story.
Can I play with friends?
Yes. Runebook is built solo-first: your story reads like a personal novel, but you can also share a story with friends. Everyone steps in, decisions get argued about, and the Storyteller weaves the group into one narrative. There are private stories for your group, public stories, and even spectators who can watch a story unfold. Think of it as movie night where you're all in the movie.
What can I play it on?
Runebook plays in your browser on phone, tablet, or desktop. No download, no install. Your story is saved to your account, so you can start a chapter on your phone at lunch and finish it on a laptop that night, with your story exactly where you left it: same people, same unfinished business.
