ArcQuill is an AI-powered tabletop RPG where the DM doesn't forget your story. Every NPC, quest, and secret is tracked in a persistent world. The AI plans plot arcs before the game starts, filters what each NPC knows based on your relationship with them, and pulls relevant memories via semantic search so games can run hundreds of turns without losing the thread. Pick a world concept, get a character, and start playing in under a minute.

I wanted to build a no-context-limit AI DM that thinks like a real DM. It keeps track of what each NPC knows and what the player knows. NPCs have layered knowledge boundaries: public facts, secret facts, and DM-only notes, filtered by how well the player actually knows them, so a stranger won't accidentally spill their hidden motives. Every entity, relationship, and event lives in Postgres with pgvector embeddings, and each turn the system rebuilds its context from scratch.
