An AI Game Master that remembers your entire campaign
AI Game Master
An adaptive AI that improvises, reacts, and builds on your choices. No scripts, no predetermined outcomes. The story goes wherever you take it.
Advanced Persistence
Semantic memory via pgvector, relationship graphs, rumors and secrets, dynamic combat, status effects, and permanent world evolution. Nothing is forgotten, nothing is static.
World Sharing & Publishing
One-click publish with short share codes, rich preview pages, custom blurbs, optional starting narration, and public directory listing. Share your creations with the world.
Forking & Lineage
Fork any published world with all entities, lore, premades, images, and rules intact. Track forks and lineage trees. Remix and republish to make it your own.
Premade Characters
Fully-statted, backstory-rich premade characters with AI portraits. Browse iconic heroes from top creators or build your own through a conversational character creator.
Image Generation
AI fantasy art for worlds, locations, entities, and characters. Context-aware prompts, one-click regenerate, natural language editing, all optimized as WebP.
Real Consequences
Actions ripple through the world permanently. Steal from a merchant and rumors spread to nearby towns. Save a village and earn allies who show up when you need them.
Collaborative World-Building
Session Zero lets you shape the world before you play. Define the tone, magic system, factions, and lore collaboratively with your AI Game Master.
Flat-Cost Turns
Whether your turn is a quick dialogue or a 1,000-word epic battle, the cost stays the same. Play long, detailed campaigns without worrying about escalating costs.
What we're building next
I'm a solo developer who's been building and rebuilding ArcQuill through many iterations. This is early access - expect bugs, rough edges, and things that break. But I'm shipping fast and every piece of feedback shapes what comes next.
