TL;DR
If you want a free, offline worldbuilding tool with no sign-up and no subscription, Chronicler is the best choice. If maps are your top priority and you don't mind a subscription, LegendKeeper has the cleanest atlas features. If you want a general-purpose note tool you can customize with plugins, Obsidian is the most flexible but requires painful setup.
What is a worldbuilding tool?
A worldbuilding tool is software for creating and organizing a fictional world: its characters, places, history, cultures, magic systems, and maps. Most work like a private wiki, where each page describes one part of the world and links to related pages. Novelists use them to keep a series consistent. Dungeon Masters and Game Masters use them to prep tabletop RPG campaigns. "Worldbuilding app" and "worldbuilding software" mean the same thing.
Most worldbuilding tools fall into one of two groups. Wiki and lore tools such as Chronicler, World Anvil, and LegendKeeper hold the encyclopedia of your world (see how to make a worldbuilding wiki). Writing apps such as Campfire organize characters, places, and plot around the story itself. General-purpose note apps like Obsidian and Notion can also be adapted for worldbuilding with some setup.
