Kanka
An online workspace for worldbuilding and tabletop campaigns, covering characters, places, organizations, maps, calendars, timelines, relationships, permissions, and publishing.
Why use it
Its free core can give a small team a searchable source of truth, while links and granular visibility keep writers, designers, and external readers aligned.
Where it fits
Use prototypes and playtests to find core experience problems while they are still cheap to fix.
What to check
Data is hosted by a third party and offline editing is limited; custom categories, recovery, themes, larger files, and expanded collaboration require an active subscription.
