Your story, your pace

Solo TTRPG play with AI

Play tabletop RPGs solo with an AI storyteller that knows your system's rules, tone, and themes. No group needed. No scheduling. Just you and the story.

What is solo tabletop RPG play?

Solo tabletop RPG play means running a full roleplaying game on your own, with no group to schedule and no separate game master. You play your character and make the decisions; something else runs the world, voices the NPCs, and resolves the rules. It has grown from a niche corner of the hobby into one of its most popular entry points, because it removes the two hardest parts of getting a game going: finding a group and finding a GM.

There are two ways to do it. Solo-first games like Ironsworn build the GM's job into the rules through oracles you consult yourself. Traditional systems like D&D, Vampire, or Call of Cthulhu were written for a human GM, so to play them alone you hand that role to an AI game master that frames scenes, plays every NPC, and calls for your rolls in real time. RPG Stack is built for the second path: bring a character in any supported system and start a session in minutes.

How it works

Build a new character or use one from your existing collection.

Launch the AI storyteller

The AI sets the scene and manages the world while you play.

Play your story

Make choices, roll dice, and shape the narrative at your own pace.

Play with an AI game master

The fastest way to play solo: an AI game master runs the world, plays every NPC and monster, and adjudicates the rules in real time while you play your character.

Ways to play solo

Oracles and yes/no tables

Answer the questions a GM would with weighted yes/no tables and random event rolls. Fully analog, endlessly surprising, and a bit of bookkeeping.

Solo journaling

Narrate your character's story in writing, using an oracle or GM emulator to resolve the uncertain moments and record where they lead.

An AI game master

Hand the whole GM role to an AI: it narrates, plays every NPC and monster, and calls for your rolls, so you skip the bookkeeping and just play your character.
