Loreleaf

Worldbuilding,
kept private.

Your world lives in your head. Loreleaf gives it a home — without giving it away.

For iPhone & iPad · A one-time purchase, no subscription

The story bible that never reads your story back to the cloud. No account. No cloud. No subscription.

Nothing you write is ever uploaded — or used to train anything.

Every character, location, faction, creature, item, event, and concept in one beautiful, searchable place — across as many worlds as you build.

Name Forge, Story Sparks, and Deepen brainstorm alongside you, powered by Apple Intelligence and running 100% on your device. Offline. Private.

One-time purchase for unlimited worlds and entries. Export any world as clean Markdown — your story bible is never locked in.

The Muse never leaves your device

Writers are right to be wary of AI that swallows their manuscripts. Loreleaf's muse is built the opposite way.

Name Forge — ten original names for anything, tuned to your world's tone.
Story Sparks — five concrete conflicts, secrets, and tensions to build on.
Deepen — sharp questions and hooks that push any character or place further.
Entirely on-device — runs on Apple Intelligence, with a graceful fallback where it's unavailable.

Seven entry types — characters, locations, factions, creatures, items, events, and concepts, each with summaries, long-form notes, and tags.
Inspiration images — attach reference photos or generate concept sketches with Apple Image Playground.
The World Web — a living map of who hides from whom, what lies where, and how your lore connects.
Instant search & filters — find anything across names, summaries, and tags in a tap.

Made for writers who'd rather their next twist stay a secret.
