What you get

Packed with features that matter

🧠

Memory System

The AI remembers what matters. Important events are automatically stored and retrieved — so your past choices shape the future, even 200 turns in.

📜

AI Quest Generation

Generate unique multi-stage quests on demand. Each quest has up to 5 stages — combat, investigation, stealth, exploration, or gathering — resolved through roleplay.

❤️

Relationship Engine

NPCs remember how you treat them. A 0–100 relationship score and 7 personality traits determine how each character genuinely responds to your actions.

🗺️

Living Worlds

Explore locations that the AI discovers alongside you. Factions, power systems, and lore all feed directly into every story turn.

🔮

Plot Builder

Enable Plot Builder and the AI writes a narrative arc before each chapter, ensuring your story always moves forward with purpose and direction.

🖼️

Image Generation

Auto-generate images for new locations and enemies as you encounter them — no extra work, just enable it in your game settings.

Intelligent systems, seamless storytelling

Every turn, multiple systems work together to keep your story coherent, alive, and personally meaningful.

🧠

Memory System

Important moments are stored as long-term memories with semantic search capability. Each turn, the most relevant memories are retrieved and woven into the AI's context — so nothing important is ever forgotten.

Token & Context

The AI sees your world context, recent story history, and retrieved memories — all balanced intelligently so the most relevant information is always available, even in very long games.
