ABOUT

An AI that becomes your own Game Master.

Pick a scenario, build a character, then just talk. The story, the NPCs you meet and the art of every scene are made on the spot, in response to your choices. There is no correct path, and no two sessions are alike.

01

What AI TRPG is

A tabletop RPG only happens when someone agrees to run it. Schedules have to line up, players have to be found, and one person carries the preparation. AI takes on that heaviest part.

Late at night, or for thirty minutes on the train, you can open a table by yourself. That is the reason this service exists.

There is no charge. Once you sign up, everything here is yours to use.

02

How the AI GM works

The GM rebuilds the next scene around the line you just typed. You are not choosing from branches written in advance.

TEXT

Writes the story as you go

Google's generative AI reads the story so far and your character's state, then writes what happens next.

IMAGE

Draws the scene

It composites the place you have reached with your character standing in it.

STATE

Remembers the world

Who you spoke to, what you carry. The session state is saved, so you can pick it up later.

03GAME MASTERS

Four GMs. The one you sit down with turns the same scenario into a different game.

You choose during character creation. Both the pacing and the temperature of the prose shift.
