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.
