Full authority over the world. Publishes the canonical baseline, accepts or rejects contributor changes, manages roles and controls what becomes canon.
The owner's word is canon.
The owner's local world copy is the authoritative version. Hosted changes and contributor edits do not silently overwrite it. Publishing a canonical baseline and accepting changes into local canon are deliberate owner actions.
The creator decides what becomes part of the world. A contributor can propose an idea, draft an entry or refine a description, but that work does not alter the owner's local files until the owner explicitly accepts it.
- Local copy remains canonical
- Hosted changes require explicit acceptance
- Contributors propose — the owner decides
- Publishing and reconciliation are owner actions
Five roles. Clear boundaries.
Every collaborator gets one of five roles. Each role has specific capabilities, and an Admin can manage substantial hosted work but does not automatically gain permission to write the owner's local files.
Manages hosted content and collaborators on behalf of the owner. Can organise, edit and moderate the hosted copy without inheriting local-file write access.
Creates and edits entries on the hosted copy. Changes remain proposals until the owner or an Admin accepts them.
Reviews and comments on existing entries. Useful for feedback and discussion without direct editing capability.
Read-only access to the hosted world. Can browse entries and follow the world's structure without modifying anything.
Propose, review, accept.
Contributors work on the hosted version. Their changes are proposals until the owner accepts them. The separation between hosted work and the owner's local canon means nobody can accidentally overwrite years of worldbuilding.
- 01 Publish a canonical baseline The owner shares a snapshot of the world for collaborators to work from.
- 02 Contributors work on the hosted copy Editors draft entries, refine descriptions and build on the shared material.
- 03 Changes are proposed for review Contributor work stays visible as proposals, not silent overwrites.
- 04 Owner accepts, revises or rejects The owner reconciles contributor work into their local canon on their own terms.

Collaboration is creation. Campaign is presentation.
Writers' Room is where creators build together. Campaign is where the GM presents a controlled experience to players, audiences or participants. They share platform services — hosting, permissions, the same underlying world — but they serve different workflows with different permission models.

- The owner decides what becomes canon
- The goal is a better, more complete world
- The GM presents the world to players

Frequently asked questions
- Can free users collaborate?
- Yes. Core users can accept invitations to join a paid user's hosted world and contribute within the host's allowance. Hosting a collaborative world yourself requires Apprentice or above.
- Can a contributor overwrite my world?
- No. The owner's local copy is the canonical version. Contributors work on the hosted copy and their changes remain proposals until the owner explicitly accepts them. Publishing and reconciliation are deliberate owner actions.
- What is the difference between Campaign and Writers' Room?
- Writers' Room is where creators build together. Campaign is where the GM presents a controlled experience to players, audiences or participants. They share platform services but serve different workflows with different permission models.
