Which worldbuilding app is right for you?
Look, all of these worldbuilding apps have their strengths. The best choice really depends on how you like to work and what you're really looking for.
If you want an aesthetic, all-in-one app built specifically for fantasy writers, where you can build your world, plan your story, create maps and timelines, track characters and relationships, and write your manuscript in one place, Quill&Steel OS is literally built for this.
If you prefer a completely customizable setup and would rather make a one-time purchase than pay for a subscription, the Notion Worldbuilding System is the better fit. It gives you an in-depth worldbuilding bible, full customization without limits, a simple interface, easy linking between entries, a timeline, and a few other neat databases.
For writers who want especially deep lore-building and don't mind a more complex interface, World Anvil is another strong option.
And if your priority is drafting rather than dedicated worldbuilding, Scrivener is worth considering.
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?
Quill&Steel OS is a great choice if you want an all-in-one app built specifically for fantasy writers, with dedicated tools for worldbuilding, story planning, workshopping, and writing your novel. If you prefer deep, highly detailed lore-building, World Anvil is another strong option, and Notion is best for writers who want a fully customizable setup.
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 Lady Fangs 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 Quill&Steel OS, 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. See this guide on how to create a fantasy map.
