Tips for Choosing

  • Start with geography and climate — everything else (culture, economy, conflict) flows from the physical world.
  • Use AI to generate contradictions in your world, then resolve them — this creates depth and realism.
  • Dedicated worldbuilding tools like World Anvil and Campfire beat general LLMs for long-term organization.
  • Ask the AI to play a citizen of your world and answer questions in character — it reveals gaps fast.
