My brother just finished writing a fantasy novel. By the time he was finished, he had created a searchable wiki with every idea, lore snippet, and references logged into his note taking app.

As easily as we would google an event in history, he could bring up the tagged items associated to a chapter, world event, or character in his book.

At the late stages, when he was modifying a lot with the help of his publisher/editor, this was worth its weight in gold.

Amazing level of discipline and wisdom choosing to set it up in that way for himself.

I would recommend similar to anyone considering writing a book.

His book was recently published and is sold in stores everywhere under the title “Gods-Forged”.
