Step into Beowulf, Dracula, or a world only the AI has dreamed. Pick from offered choices — or type whatever you want. Every choice rewrites the next page.
Not an audiobook. Not a chatbot. A tale that bends to every move you make, written in the voice of the world you stepped into.
Eighty-seven bundled classics — Dracula, Sherlock, Beowulf, the Odyssey — each with a hand-curated AI scenario. Plus myth, folklore, history, stage, and epic-poetry worlds. Or invent your own.
Streaming prose arrives a sentence at a time, in the voice of the world you stepped into — beneath a painted cover conjured for your story.
Pick from three offered branches, or type whatever you want. The story adapts.
Every turn, the AI writes the next page in the voice of the world you're in — then hands you the pen. Pick a branch or type anything at all, and it remembers: your choices carry forward turn after turn, so a single run can unfold for hours and never repeat itself. Here's one turn.
Three bells past midnight, and Halen breathes the kind of quiet that belongs only to cats and thieves. The mist sits low on the canal, smelling of brine and old rope, and the cold of the tiles seeps through your boots like a slow debt.
The turn shown on the phone, set in readable type — a live run of the real Prismshard Heist scenario. Each turn opens with a scene the app paints for it; every branch is written fresh, so no two runs are the same.
Six of the worlds waiting inside — horror, fantasy, sci-fi, mystery, high-seas adventure, and the Old West. Each opens under a cover the app paints for it, then branches turn by turn from the premise below. Every classic on the shelf has one too, and the original worlds are built for nothing else.
Plus 87 classics with scenarios in the source's own voice, and whole shelves of myth, folklore, history, stage & screen, and epic poetry — 190+ scenarios in all.
A literary engine, a quiet reader, a trophy gallery — built like a chef's knife, not a Swiss army.
Eighty-seven public-domain books pre-loaded — Dracula, Pride & Prejudice, Sherlock Holmes, Treasure Island, the Odyssey, and 82 more. Each has its own AI Adventure scenario calibrated to the source's voice.
Sketch a premise — title, genre, characters, a plot seed. The AI weaves a branching tale around it, keeping continuity across every turn.
Every book and adventure gets a painted cover in a Victorian-engraving-meets-illuminated-manuscript style — 87 painted classics, plus a fresh cover conjured for each story you start. In AI Adventure, every turn opens with a new scene the app paints for the moment.
Saved books open into a clean, themable reader — adjustable size, serif/sans/mono, light/sepia/dark, chapter narration that reads aloud, and navigation that remembers where you left off.
Achievements for completing books, finishing scenarios, writing your own moves, and reading across genres. Stats track your library, finished reads, and turns played.
Saved adventures and reading progress live on your device — no account, no login, no telemetry tied to your name. The AI never trains on your stories.
A literary luxury aesthetic, hand-built one screen at a time.
Every screen ships in light and dark — warm parchment by day, deep violet night mode after hours. Painted covers with first-page previews, a story composer built to write like a novelist, achievements on your profile, and community Tales.
All public-domain. All offline-readable. All yours to keep.
Three free AI Adventure turns every month. Pro removes every cap.
Everything reviewers, readers, and parents ask us.
No — the AI uses the book's world and voice as the setting, but every adventure is its own continuity. You're not reading Dracula. You're at Castle Dracula, making choices Jonathan Harker never had.
It happens. Tap "Try again" on any turn to regenerate, or type a different choice to steer the story. The system prompt is tuned to keep prose in-period and on-tone, but AI is AI.
No. Your input is sent to our backend for the duration of the request, forwarded to OpenAI for generation, and not stored on either end. We don't sell or share your input.
The 87 bundled books are fully offline-readable. AI Adventure requires a network connection — every turn is generated live by the model.
You keep access through the end of the current period, then drop back to the free tier (3 AI Adventure turns / month). Your saved adventures and library stay — they're on your device.
StoryVault is built around literature — period-correct prose, hand-tuned scenarios, a real reader for the source books. The AI keeps you in the source's voice instead of letting the story drift into generic fantasy.
iOS first. iPad works on the same iOS app. Android and Mac are on the roadmap but not committed yet.
The bundled library is all public-domain material rated 12+. The AI Adventure system prompt explicitly excludes explicit sexual content and child endangerment. Reach out at dmusk188@gmail.com for review codes.
