How it works

A page. A choice.
A new page.

A tale that bends to every move you make, told in the voice of the world you stepped into.

  1. Pick a tale

    Start with one of 80 classics, from Dracula to the Odyssey. Wander into myth, folklore, history, the stage, or epic poetry. Or invent a world of your own.

  2. Read what the AI writes

    The next page streams in a sentence at a time, beneath a painted cover made for your story.

  3. Choose what happens next

    Take one of three branches, or type any move you like. The story follows.

Alice in Wonderland book detail in dark mode — painted cover, Fantasy tag, chapters, and first-pages preview

Whichever you pick becomes the next page, and your choices carry forward from there.

The headline act

AI Adventure. Your move.

Each turn, the AI writes the next page and hands you the pen. It remembers what you chose, so a single run can go on for hours. Here's one turn.

One live turn, five real frames — your move, then the next page
Dracula · a live turn · your move

You press your forehead briefly against the cold window glass. Below, the square is empty. A wisp of cloud moves across the bone-pale moon. And then — at the far edge of the market square, quite still among the shadow — something. A shape that may be a driver. A shape that may be a coach.

1 Take the landlady's crucifix and board the midnight coach
2 Refuse to board until daylight; demand another night at the inn
3 Slip out and speak directly to the driver before departing
Or type your own — "Type a custom move, or ask a what-if…"

This is the phone's final frame, set in readable type. It comes from a real run of the Dracula scenario, streamed live on the free tier.

250+ doors, one vault

What's inside

Every classic. Every choice.

An AI storyteller that plays along, and a quiet reader for the books themselves.

Live a classic

Eighty public-domain books come with the app, Pride & Prejudice and Treasure Island among them. Each has an AI Adventure that drops you into its world.

Or a world only you know

Sketch a premise with a title, a genre, characters, and a plot seed. The AI grows a branching tale from it and keeps the story straight, turn after turn.

Painted, not printed

Every book has a painted cover, part Victorian engraving and part illuminated manuscript. Each story you start gets one of its own. With Pro, AI Adventure paints the scene as you play, up to 10 turns a day and 100 a month.

A reader, too

Saved books open in a clean reader. Set the text size, pick serif or sans, go sepia or dark, and have the chapter read aloud. It remembers where you left off.

Earn the trophies

Achievements mark the books and scenarios you finish, the moves you write yourself, and how widely you read. Stats keep count of your library, finished reads, and turns played.

Yours alone

Your saved adventures and reading progress live on your device. No account needed to read or play, and AI providers’ API terms exclude your stories from model training by default.

Common questions

FAQ

Everything readers and parents ask us.

Is the AI just rewriting the original book?

No. The AI borrows the book's world and voice, but your adventure goes its own way. You're not reading Dracula. You're at Castle Dracula, making choices Jonathan Harker never had.

What if the AI says something off?

It happens. Choose Undo last turn from the menu at the top right to take the turn back and pick again, or type a different move to steer the story. It's tuned to stay in period and on tone, but it can still miss.

Does the AI train on my stories?

Nothing is sent to an AI provider until you allow AI sharing in the app. After that, your input goes through our backend to Anthropic's Claude to write the next page (with OpenAI as a failover), and to OpenAI for scene art and voice narration. Their API terms exclude it from model training by default, and we never sell it. What we and those providers may keep, and for how long, is set out in the privacy policy.

Can I read offline?

Yes. All 80 classics read fully offline. AI Adventure needs a connection, since every turn is written live.

What happens if I cancel Pro?

You keep access through the end of the current period. Your saved adventures and your library stay on your device, and all 80 classics remain free to read. The 10 free AI Adventure turns are a one-time welcome for new readers, so if you have already used them, new AI turns need an active subscription.

How is this different from AI Dungeon?

StoryVault starts with literature: hand-tuned scenarios, prose true to its period, and a real reader for the source books. The AI keeps you in the source's voice, so Dracula still sounds like Dracula.

Which devices does it run on?

StoryVault is for iPhone today, on iOS 17 or later.

I'm a teacher / parent / reviewer — how do I evaluate it?

StoryVault is rated 13+ on the App Store because of the community Tales feed. The bundled library is public-domain literature, and AI Adventure is instructed never to write explicit sexual content or anything that sexualizes minors. If a choice pushes that way, the story turns aside. Email support@hypersage.ai for review codes.
