QuestHold AI

A storytelling game with an AI Game Master on your phone or tablet. Imagine any world. Play them for years.

Any world you can describe, built from your own words, with its own people, places and dangers.
You roll every die. The AI tells the story; the game's rules and your dice decide what happens.
Talk and listen, or read and type. Every character speaks in a voice of their own.
Friends at your table, from their own phones or tablets. Rise to level 30 and become a Legend.
On your own device, offline. No account and no subscription.
