Sketch a world.
An AI Game Master brings it alive.

MyAdventures.AI is a solo tabletop RPG you play in your browser. An AI Game Master narrates the story and plays every NPC, a real rules engine rolls dice it can’t fudge, and everything the AI invents is recorded once and stays true forever.

The AI tells the story. The dice tell the truth.

A real turn: your intent, a rules-engine roll, and narration that owns the result. Watch the ring enter your inventory — the world just learned a fact it will never forget.

The overworld

Walk off the edge of the map.

Hex by hex, the world reveals itself — terrain, roads that dead-end into fog, weather that closes in. Your trail stays where you left it, and day 12 is still day 12 when you come back.

One continuous atlas

From star map to street map.

Every world is one map, drawn at every altitude. Zoom from a galaxy of sectors down to the tunnels of an asteroid warren, or from the wheel of realms to the streets of a town — each layer generated once, then remembered exactly. These are real captures from play.

real captures from play — not concept art
A realm wheel on deep blue: three realms — the Heartland, the Void, the Fractured — arranged on a ring, joined by a solid overland route and a dashed portal route
The realm wheelThe top of the atlas — whole realms on a wheel, bound by overland roads and the portals that cross between planes.
Tactical combat

When talk breaks down, the grid comes out.

The same scene, snapped onto a battle map. Real positions, six-second rounds, no fudged fights.

Narrative arcs

The story notices the moment you make it happen.

Authors write beats and plot threads. Watchers listen to the fiction. Win the witch's trust — in whatever words you choose — and the next chapter unlocks itself. No scripts. No railroads.

■ Game MasterThe witch watches you over the ledger — the one page that could ruin her. She makes no move to take it back.
■ YouI hand it back to her, unread. “Your secret keeps. I gave my word.”

Record once, resolve forever

Invented once. True forever.

When the GM improvises a ring, a goblin, a grudge — it's recorded at the moment of creation, and the rules resolve it ever after. Fire seven arrows and you have seven fewer.

The Game Master takes note…

Why it's different

An AI storyteller that stays honest

Generative AI is brilliant at story and terrible at bookkeeping. We let it tell the tale — and let real tools keep the world consistent.

It remembers

A persistent memory of your world — the orc ambush three sessions ago, the favour you owe a smuggler, the bridge you burned.

Any system you like

5e-Compatible out of the box — or build your own ruleset for a sci-fi survival game, a PbtA drama, or homebrew d10.

Built to be shared

Publish your worlds — each with a browsable lore wiki — or fork someone else's and make it your own. A whole community of adventures.

Describe it — or build it by hand

Build your worlds your way

Answer a handful of questions and the AI drafts a playable ruleset, world and story — or open the workshop and hand-place every hex, faction and plot beat. Either way the AI co-authors beside you, and you can come back and tweak whenever inspiration strikes.

How it works

1

Describe, pick, or build

Start a community story in a click — or describe your idea and the AI generates the ruleset, world and story to play it.

2

Make a hero

Roll up a character in your chosen system — race, class, backstory and all.

3

Play forever

Explore, fight, scheme and remember. Pick up exactly where you left off, anytime.

Questions, answered straight

Frequently asked

Does the AI fudge dice rolls?

It can’t. Every check, attack and save goes through a rules engine outside the AI — the AI asks for a roll, the engine rolls it, and you watch each die land live. The AI then narrates the result it was given, success or failure.

Can I play a 5e game solo with an AI Game Master?

Yes. The built-in 5e-Compatible system implements the SRD 5.1 rules — character creation, skills, spells, combat and levelling. Make a hero in minutes and the AI Game Master runs everything else: the world, the monsters, and every other character at the table.

What can I actually do in an adventure?

Anything you can say. Explore the overworld hex by hex, wander towns and dungeons, talk your way through trouble, trade with merchants, pick up loot the world remembers, recruit companions, and fight when talk breaks down. The Game Master improvises the story; the engine keeps it all real.
