FAQ
I only see empty Point of view and From/to narrative fields.+
That means no version is saved yet. Write the market belief, then the from/to shift. Save a version before chat can preview this model.
If I fill Category Design here, does it change other workspaces?+
No. The agency picks which frameworks exist (Settings u2192 Agency u2192 Marketing models). Each workspace saves its own versions. Filling Category Design for this client does not overwrite another client.
Does Edit also publish Category Design for chat?+
No. Edit then Save writes a draft version. Chat preview and @mentions of strategy models use a published version. See Save and publish a strategy model. Revert a strategy model version and Use the strategy model assistant are separate jobs on the same page.
I can preview Category Design but I cannot save. Why?+
Viewing needs strategy read. Save, publish, unpublish, and revert need strategy update. Ask an admin. The assistant on the right can draft a change; applying it also needs strategy update.
