Short answer: At launch, each project on Vizno has a single owner - there is no way to add a second creator as a co-creator or co-owner of the same project. Multi-creator collaboration is planned for a future release, but no date has been confirmed yet.
What this means at launch
Right now, only one Vizno account can own and manage a given project. That owner is responsible for all authoring, publishing decisions, and account-level settings tied to the project. If you are working with a writing partner, artist, or co-writer, only one of you can hold the project under their account.
Workarounds while collaboration tooling is unavailable
Because there is no built-in co-creator support today, teams working together typically share assets and Folio scripts outside of Vizno (for example, using a shared drive or version-control repository) and have the designated project owner import and publish the work. Any revenue, rights, or credit arrangements between collaborators are handled entirely outside the platform for now.
What to expect in the future
Multi-creator co-ownership is on Vizno's roadmap. When it becomes available, it is expected to allow more than one account to share ownership or editing rights on a single project. Until that feature ships, this page will be updated with specifics. Check back here for the latest status.
