The Only D&D Group You'll Ever Need(That Actually Shows Up)
No scheduling. No flaky players. Just you and an AI Game Master with a real D&D 5e rules engine — real dice, persistent worlds, and a referee that isn't afraid to say no.
See it in action
This Is What a Turn Looks Like
Real dice. Real consequences. The AI narrates — the engine enforces.
I try to sneak past the sleeping guard into the armory.
Stealth Check: 1d20 + 5 = 14 vs DC 12 — Success!
You press yourself against the cold stone wall, timing your steps with the guard's heavy snoring. The armory door is ajar — inside, moonlight glints off a rack of fine longswords. But there's a second guard you didn't see, sitting in the shadows with a half-eaten apple.
I grab the nearest sword and try to talk my way out of it.
Deception Check: 1d20 + 1 = 6 vs DC 15 — Failure.
"Nice try, thief." The guard drops the apple and draws his blade. Roll initiative.
A game engine, not a chatbot
The AI Narrates. The Engine Enforces.
Questhelm splits the job in two: the AI tells your story, and a deterministic D&D 5e rules engine enforces the mechanics. Neither can override the other.
Rules Are Real
A full D&D 5e mechanical simulation — not prompt engineering. A Level 1 Wizard cannot cast Fireball. The system blocks it before the AI ever sees it. Every dice roll is computed, verified, and shown with the math.
The World Remembers
Dead NPCs stay dead. Broken promises have consequences. A structured memory system tracks your narrative arcs, NPC relationships, and world events across every session. The AI cannot contradict what's already happened.
Failure Is Real
The AI isn't your friend — it's an impartial referee. Character death is mechanically possible. Bad decisions have lasting consequences. When you survive a fight by one HP, you earned it.

Combat Conditions
Everything a Good DM Does
Enforced by a system that never gets tired, never fudges rolls, and never loses your character sheet.
Living Character Sheet
HP, spell slots, inventory, conditions — all tracked by the engine. Use a potion? Your inventory updates. Take damage? Your HP drops.
Transparent Dice Rolls
Every roll shown with the math: 1d20 + 5 = 18 vs AC 16 — Hit! You see exactly why you succeeded or failed.
Mechanical Enforcement
Out of spell slots? You can't cast. No Thieves' Tools? No lockpicking proficiency. The engine doesn't make exceptions.
Real Combat
Initiative order. Action economy. Opportunity attacks. Death saving throws. Tactical, tense, and consequential.
Pick Up Where You Left Off
Your campaign saves automatically. Come back tomorrow and everything is exactly where you left it.
NPCs That Remember
Steal from a shopkeeper? They remember 5 sessions later. Every NPC relationship evolves based on what you actually did.
Questhelm vs. ChatGPT / AI Dungeon
Other AI DMs are chatbots that narrate. Questhelm is a game engine that enforces.
