FAQs about the best world building apps

What is the best free world building app?
Notion is one of the best options. It gives you full creative control so you can build a worldbuilding system that is made for your specific needs. You can learn how to structure Notion for worldbuilding here.

Which worldbuilding app is best for fantasy writers?
World Anvil is great if you want to dive deep into lore. But if you want clean organization and full customization without the overwhelm, Notion (especially with a good template) is your best bet.

Can I use Notion for worldbuilding?
Absolutely — and it's fantastic for it. With a good setup, you can track locations, characters, cultures, religions, magic systems, and even timelines, all neatly interconnected.

Is it better to use a worldbuilding app or just a notebook?
It depends on how your brain works. If you love flipping through physical notes and don’t mind a little chaos, a notebook can work fine. But if you want to actually find what you wrote about the Duke of Nowhere three months ago without digging through piles of paper, a worldbuilding app is going to make your life a lot easier.

Can I build a fantasy map inside a worldbuilding app?
Yes, some of the best world building apps like World Anvil, Campfire, and LegendKeeper let you create interactive maps. If you’re using a tool like Notion, you can link locations manually, but for actual fantasy map drawing, you might want to pair it with a visual tool like Wonderdraft or Inkarnate.
