Generate campaign codex documents filtered by timeline to create player handouts with known information while keeping secret lore separate for your GM reference

How It Works
SOJEN transforms your jungle campaign vision into a fully realized world through structured world-building. Create entity profiles for ancient deities, tribal factions, ruined temples, and mystical creatures. Develop canon entries for the rise and fall of lost civilizations, exploration events, and discovery stories. Organize everything with timelines to track different historical eras—from the height of ancient empires to their mysterious collapse. Generate comprehensive codex documents filtered by timeline period to create player handouts about known ruins, while keeping secret lore hidden. Connect NPCs, locations, and artifacts through relationship tracking so your world feels interconnected. The AI assistant helps maintain consistency across your campaign, suggests new connections, and helps you develop rich backstories that bring your jungle world to life.
