Built by a worldbuilder, for worldbuilders

Realmweaver was built by James Fazio, an award-winning filmmaker, author, and worldbuilder. James wrote, directed, and edited Time Well Spent, a festival-winning feature documentary streaming on Prime Video, and created Shibui Universe, a dark fantasy franchise whose manga Eternal Blade is published on MangaPlus.

After years of building a fictional world across manga, anime, and games, James wanted a tool that could keep a whole world consistent: its history, characters, factions, and lore. Nothing he tried did that, so he built Realmweaver, an AI worldbuilding app for novelists, game masters, and game designers who want their worlds to hold together from the first page to the hundredth session.
