Local Realm is an offline-first worldbuilding tool for writers, game developers, and TTRPG creators. Build interconnected characters, locations, factions, timelines, maps, and lore in a flexible local database with no accounts, subscriptions, or cloud dependency required.
Local Realm is built around interconnected entries rather than isolated documents.
Create a character once and reference them across locations, factions, events, timelines, maps, relationships, and written material. Rename or update that character later, and their connections remain intact.
Use references, backlinks, tags, aliases, and relationships to turn your setting into a navigable knowledge base.
Every setting is different, so Local Realm doesn't force you into a predefined collection of fantasy templates.
Create your own entry types, such as:
Characters
Nations
Cities
Planets
Species
Religions
Corporations
Military units
Starships
Magic systems
Technologies
Historical events

Define custom properties for each type, including text, numbers, dates, images, categories, and references to other entries.
Whether you're building a medieval kingdom, a sprawling space opera, an alternate history, or a campaign setting, your database can adapt to your world.
Explore your world beyond simple articles.
Use interconnected tools for:
Interactive Maps
Import or use the built-in mapmaking tools to make your own maps and add locations, regions, labels, routes, and layered information without modifying the original artwork.

Timelines
Track wars, reigns, discoveries, character lifetimes, and historical eras using real-world or fictional calendars.
Relationship Graphs
Visualize connections between characters, factions, places, events, and other parts of your setting.
Relationship Trees
Build family trees, political hierarchies, military organizations, pantheons, corporate structures, and other manually arranged diagrams.

Keep your lore close while writing by organizing stories into chapters, track drafts and notes, and open relevant world entries alongside your manuscript instead of constantly switching between applications.
Link characters, locations, and other entries directly from your writing so you can quickly check details while you work.
As worlds grow, use global search across your project, including names, aliases, tags, properties, articles, notes, and other content.
Backlinks show everywhere an entry is referenced, helping you discover connections you may have forgotten.

Keep artwork, maps, portraits, diagrams, documents, and other media inside your project.
See where files are being used and organize visual references alongside the world information they belong to.
Local Realm isn't limited to one kind of worldbuilding.
Writers can maintain setting bibles and story continuity.
Game masters can organize campaigns, factions, locations, NPCs, history, and reference material.
Game developers can structure world data, dialogue, characters, items, factions, and locations before exporting information for use elsewhere.
Local Realm is designed around ownership and portability.
Your project lives on your machine rather than being locked behind an online service.
Work without an internet connection, create your own backups, move your project between computers, and keep control over where your creative work is stored.
Export you manuscript into common formats (DOC, EPUB, MS and PDF) for backup, publishing, sharing, or use in other tools.
