Worldbuilding Is Hard Enough

Your tools shouldn't make it harder. Sound familiar?

"I forgot that character's eye color"

You described them differently in Chapter 3 and Chapter 27. Your beta reader caught it. Embarrassing.

"The timeline makes no sense"

Character A can't be in both the castle siege and the forest ambush at the same time. But your word processor doesn't know that.

"My notes are scattered everywhere"

Character sheets in one app, maps in another, timeline in a spreadsheet, magic system rules in a random Google Doc from 2019.

"The tool is more complex than my world"

You spent more time learning the software than actually worldbuilding. Hundreds of fields you don't need. Features you'll never use.
