Start with one core concept that excites you — a magic system, a unique culture, or an interesting geography. Build outward from there. AI can help you explore implications and fill in details systematically.
Build what serves your story. Readers need to understand the world through the narrative, not info-dumps. AI can help identify what details matter and what can remain in your notes.
Keep a world bible with rules, facts, and details. Reference it constantly. AI can help track consistency and flag contradictions as you develop new aspects of your world.
Full conlangs require serious linguistic knowledge. For most stories, creating naming conventions, key phrases, and flavor words is enough. AI can help generate consistent naming patterns.
Combine familiar elements in unexpected ways. Draw from underused historical periods and cultures. Let AI help you brainstorm unusual combinations and push beyond clichés.
