World of Promptcraft is a 3D multiplayer RPG you play like any other — explore with WASD and your mouse (or touch on mobile) and fight your way across a vast fantasy world. What's new is everything you type: each NPC is an autonomous AI agent you chat with in a text box, and a World Builder raises NPCs and structures on command — written in plain text, built by the game's AI.
Every NPC is a fully autonomous AI agent with its own memory, personality, and mood. They remember your name, your past actions, and how you treated them. Befriend a merchant and she'll give you discounts. Insult a guard and he'll hold a grudge.
Combat rewards creativity — a plain "I attack" deals glancing damage, while a vivid "I vault off the crumbling wall and drive my blazing blade into the dragon's eye" can be devastating.
"The most innovative RPG interface I've seen in years. It's like playing D&D with a Dungeon Master that never sleeps."
A small, AI-first crew building the agentic systems behind the game — autonomous LangGraph NPC agents, an LLM-driven World Builder, the 3D world, and the infrastructure that runs it all.

Pick a name, race (Human, Elf, Dwarf, Orc), and faction (Alliance or Horde). You spawn in a vast fantasy world.
Move with WASD and your mouse — or touch controls on mobile. Roam lush forests, volcanic badlands, frozen tundras, and ancient ruins. Every step reveals something new.
Walk up to any character and a text box opens. Instead of a dialog tree, you type whatever you want — and an AI agent writes back in its own style, remembers you, and draws on the world's lore.
Type a request for a quest, a trade, a fight, a joke, or a deal — the AI responds instantly. Or call on the World Builder: type out a tower, a bridge, or a brand-new character, and watch it appear.
Damage numbers fly, particle effects ignite, NPCs emote, weather changes, music swells — all driven by your words.
World of Promptcraft is still in the forge. Leave your email and we'll let you know the moment it's ready to play.
