“Scenario: a torch-lit dungeon, a locked iron door ahead”

2 AI perspectives
GMDungeon Master (AI)

The door is bound in rusted iron, and a riddle is scratched beneath the handle: "I have keys but open no locks." Behind you, something heavy drags across the stone. Do you answer the riddle, force the door, or turn to face the sound?

Shield up, torch low. Whatever that is, it is big and in no hurry. Hurry up with your poetry, scholar.

The iron bands loosen with a groan. Cold air pours out, carrying the smell of old parchment. In Brenna's torchlight, two pale eyes appear at the end of the corridor. You have one move before it reaches you.

§ 01 · Why Debatly

What you get

In short

An AI dungeon master is an AI that runs a tabletop-style roleplaying game: it narrates the world, plays every non-player character and resolves the consequences of your actions. With Debatly you can play with a game master character or a roleplay scenario with objectives, and add AI companions in a group room where an AI director manages who acts next.

Dungeon crawls, space opera, noir mysteries, horror or your own homebrew setting, ready in one message.

02

A party of AI companions

03

Scenarios with objectives

Start from a roleplay scenario with a clear goal, so every session has stakes and an ending.

04

Devil’s advocateOne AI attacks your idea as hard as it can, so you find the weak spots first.

How it works

  1. Set the scene

    Pick a game master character or scenario, or describe your own setting, tone and character in one paragraph.

  2. Say what you do

    Describe your actions in plain language. The GM narrates consequences, voices NPCs and keeps the world consistent.

  3. Add a party

    Open a group room with AI companions who act in character, argue about plans and react to the GM.

How to start a great solo RPG session with AI

Give the GM a session zero in your first message: genre and tone ("grim low-fantasy, no chosen ones"), your character (name, one strength, one flaw, one goal), the content you want to avoid, and how much structure you like. Ask the GM to end each turn with a clear situation and let you decide, rather than listing options, if you want more freedom.

Stakes make stories. Ask the GM to track something that can run out (torches, days until the eclipse, trust with a faction) and to let bad decisions have real consequences. A story where you cannot fail stops being a game.

Playing with a party of AI companions

In a group room you can add a GM and up to 4 companions with distinct personalities: a cautious healer, a reckless fighter, a rogue with a secret agenda. The AI director picks who speaks, and autonomous turns let the party argue among themselves about the plan. Give companions goals that sometimes conflict with yours; intra-party tension produces the best moments at real tables too.

Tips for long campaigns

Turn on memory so recurring characters remember key events. At the end of each session, ask the GM for a short recap and a list of open threads, and paste it at the start of the next one. Keep a simple canon: the names of places, factions and NPCs. If the story drifts, say so out of character ("OOC: let us return to the heist plot") and the GM will steer back.

Vary the pacing like a human GM would. Alternate combat or danger scenes with quieter moments: a campfire conversation with a companion, a tense negotiation with a merchant, a puzzle. Ask the GM to introduce a complication every few scenes, and to reveal secrets gradually instead of all at once. Mysteries and betrayals land harder when the clues were there all along.
