Your personal AI dungeon master — ready for any campaign, any character, any world. Persistent memory, d20-style mechanics, and a DM that never forgets a single name or quest.

Campaign: Thornwood Crypt
⚔ Dungeon Master
You approach the iron gate of Thornwood Crypt. The air reeks of old stone and sulfur. Runes glow faintly above the arch. Roll Perception DC 14.
🎲 Aldric rolled d20 — 17
Aldric the Fighter ⚔
I draw my sword and step through.
⚔ Dungeon Master
Sharp eyes, Aldric. The runes are wards — old magic against the undead. Inside, torchlight flickers on crumbling walls. You hear something breathing in the dark. What do you do?

An AI that tells stories, not just answers

DMGoblin's DM runs on Claude, Anthropic's most capable AI. It knows your character, remembers your choices, and weaves a living narrative that reacts to everything you do.

🎭
In-character narration
Rich, atmospheric storytelling that matches your chosen tone — dark fantasy, high adventure, horror, or beyond.
🎲
Dice-driven decisions
The DM calls for rolls at the right moments. Your result — not the AI's whim — determines what happens next.
📜
Full context awareness
Every message is sent with your character sheet, active quests, known NPCs, and recent story — nothing is forgotten.
Active Session — Aldric, Fighter Lv. 4
⚔ Dungeon Master
Theron slams his hammer on the anvil and turns to face you. "I don't trust adventurers, Aldric. Last ones who passed through stole my finest blade." He narrows his eyes. Persuasion or Intimidation?
Context Injected

👤 NPC: Theron — Blacksmith, distrusts party

A world that remembers everything

Every NPC you meet, every quest you accept, every location you visit — tracked automatically. The DM injects this history into every message so your world stays consistent across sessions.

👥
NPC tracker
Characters introduced by the DM are logged with their role, alignment, and your relationship status.
📋
Quest log
Active, resolved, and failed quests — always visible on your sidebar and always in the DM's memory.
🧠
Session summaries
After every 10 messages, a background process extracts key events into structured data for long-term recall.
