Design races, factions, maps, and timelines that actually stay consistent — then export your world to PDF, Markdown, or straight into your game engine. In the cloud with your team, or as free files on your desktop.
Characters in one doc, regions in another, timeline in a third. Nothing links together, and nobody has the whole picture.
The capital city has three names and two histories. Everyone notices — right after it ships.
Everyone edits the same wiki and overwrites each other. New joiners can't tell what's canon and what's an old draft.
Want lore in the engine or a PDF? Re-type it all by hand — and it's outdated the moment you paste it.
IMSC is the fix: characters, maps, and timelines as real, connected entities — consistent by construction, shared with your team, and exported in one click.
Your world isn't paragraphs — it's regions, factions, races, characters, and events. In IMS Creators they're real entities with real links. Edit one, and every reference updates across the whole project.
Design unique cultures with a system of interconnections — appearance, behavior, and social structures as structured fields. Link every character to their region, faction, dialogue, and the tasks that bring them into the game.
Create detailed maps with an easy-to-use editor — drag and drop objects, customize terrain, and visualize geography. Every location can be a real entity, linked to the characters, factions, and quests that live there.
Develop complex event timelines with cause-and-effect relationships between key historical moments. Every event links forward and backward — so the fall of the empire and the rise of the rebellion stay consistent with each other.
Export finished materials to PDF, Markdown, or JSON/CSV for use in game engines like Unity and Unreal. The lore for the writers' bible, the data for the engine — from the same source, never re-typed.

Work on the project simultaneously with your team: assign roles, track changes, and discuss edits as they happen.
See who changed what, when. Review edits, restore older versions, and keep lore decisions traceable.
Tables, galleries, checklists, and diagrams inside your docs — no more cramming lore into plain paragraphs.
Turn your world into a beautiful PDF or clean Markdown for writers, publishers, and pitch decks.
Export entities to JSON or CSV in the shape your engine expects — Unity, Unreal, Godot.
Connect characters to regions, factions to history, quests to maps — and keep it all consistent.
Notion — Flexible, but your world is just pages; no real entities, no map editor, no engine export.
World Anvil — Great templates, but heavy, subscription-driven, and locked into its platform.
IMSC — Characters, maps, and timelines as real connected entities, with PDF and engine export — and a free local-first desktop app on top of the cloud workspace.
