Magic System Builder

Design airtight, immersive magic systems — right in your browser, no app or subscription.

 This interactive HTML dashboard gives fantasy and speculative-fiction writers a dedicated workspace to build, document, and balance every layer of their magic system — from core rules and power sources to costs, limitations, and lore.

 Everything runs locally in your browser. No subscriptions, no cloud, no complexity — your worldbuilding notes never leave your computer.

 WHAT YOU GET:

 — Define the source and structure of your magic — elemental, divine, arcane, and more

 — Set hard rules, soft rules, and the consequences of breaking them

 — Track power costs, user requirements, and physical or mental tolls

 — Log spells, abilities, and artifacts with rich detail fields

 — Map how magic interacts with history, society, and economy
