Our take

Lets clients read and write structured fictional world data using the OnlyWorlds schema with many linked element types. It is for narrative, game, or lore-heavy projects that need consistent worldbuilding data rather than plain text notes. The concept is specific and coherent, but it depends on adoption of its underlying standard, which makes it somewhat niche.
