Questions and answers
Frequently asked questions
Are the worldbuilding tools free?
Yes. The tools on this page work in your browser without requiring a Summon Worlds account.
What should I look for in a worldbuilding website?
Choose a worldbuilding website that matches the job in front of you. A focused generator is useful for one quick decision, a template helps you plan the setting, and connected software keeps characters, locations, lore, and relationships organized as the world grows.
Which tools are best for writers and game masters?
Writers can begin with the complete template and story-focused learning path. Game masters can use the template, NPC generator, calendar maker, and campaign-focused path. Both can continue in the Summon Worlds app when they want to connect and revisit everything they create.
Where are my results saved?
Tools that save progress keep it on your current device. Use the available copy or download action when you want a portable backup.
Can I continue an idea in the Summon Worlds app?
Yes. Copy or download the result, then use it as the starting point for a world or summon in the mobile app. Automatic website-to-app syncing is not available yet.
