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 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.
Three offered branches — or a move you type. The branch you pick becomes the next page, and your choices carry forward.
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. With Pro, turns are illustrated with a scene the app paints for them — up to 10 a day; 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 its own painted cover, 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 80 classics with scenarios in the source's own voice, and whole shelves of myth, folklore, history, stage & screen, and epic poetry — 250+ scenarios in all.
A literary engine, a quiet reader, a trophy gallery — built like a chef's knife, not a Swiss army.
Eighty public-domain books pre-loaded — Dracula, Pride & Prejudice, Sherlock Holmes, Treasure Island, the Odyssey, and 75 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 — 80 painted classics, plus a fresh cover conjured for each story you start. In AI Adventure, Pro paints a fresh scene for the moment — up to 10 turns a day, 100 a month.
Saved books open into a clean, themable reader — adjustable size, serif or sans, brand/sepia/dark themes, 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 needed to read or play — signing in is only for publishing to Tales — and 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.
All 80 classics are free to read. Your first AI adventure is free too — 10 turns, enough to finish one story. Pro carries on from there.
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 Anthropic's Claude to write the next page (with OpenAI as a failover), and to OpenAI for scene art and voice narration. It isn't stored on either end, and we don't sell or share your input.
The 80 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. Your saved adventures and your library stay — they're on your device, and all 80 classics stay 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.
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.
iPhone first. iPad and Mac are on the roadmap; Android is not committed.
StoryVault AI is rated 13+ on the App Store — the community Tales feed sets that floor. The bundled library is public-domain literature, and the AI Adventure system prompt explicitly excludes explicit sexual content and any content that sexualizes minors.

Free to try. Eighty classics already in the vault. The next one is yours to write.
