Nancy Drew had ghostwriters. So do these apps.
A century ago the Stratemeyer Syndicate turned out Nancy Drew and the Hardy Boys like this: one man wrote the plots, and hired writers finished the books under made-up names.
Sidequest Syndicate is the same idea for apps. One person plots them and a cast of AI agents builds them, in public.
