AI Dungeon alternative for authored stories
AI Dungeon improvises a story as you type. Pominis helps you author a fixed story with choices that others can play. How they differ, and who fits which.

AI Dungeon and tools like it made a new kind of play popular: you type what you do, and an AI narrator improvises what happens next. There is no script and no fixed ending. Every session is different, and the story goes wherever you push it.
People look for an alternative for different reasons. Some want the same open-ended play elsewhere. This article is for the other group: people who enjoyed the improvisation but want to make something that stays put, a story with a shape, written choices, and an ending that others can play the same way and talk about. That is a different kind of tool, and it is what Pominis is for.
Improvised play versus an authored story
In an AI-narrated sandbox, the AI is a live storyteller and you are the player. The story exists only in your session: it is generated as you go, it is different each time, and it can follow any idea you type.
In Pominis, the AI is a collaborator and you are the author. You describe the story; the agent drafts the scenes, dialogue, choices, and art; you revise them; and then the story is fixed. A reader chooses between the options you wrote, and two readers who make the same choices see the same scenes. The AI does its work before anyone plays, not during.
One premise, played both ways
Take an invented premise: you are the purser on a cargo ship when customs officers board at dawn, and you know one crate is not what the manifest says.
Played in an open-ended sandbox, you might bribe an officer, hide in the crate, start a mutiny, or open the crate and find something the narrator invents on the spot. The pleasure is the surprise, including your own. The downside is that the story can drift, forget what it established, or lose its tension, and if you want someone else to have the same experience, you cannot give it to them.
Built as an authored story, you decide in advance what is in the crate and what the choices are: declare it, hide it, or let the captain take the blame. Each choice has consequences you planned, the crate's contents pay off in every ending, and the officers and the captain look the same in every scene because they were designed once. The player has less freedom and a tighter story, and you can send the link to anyone.
Side by side
- Player input: a sandbox takes free text; an authored story offers written choices.
- Consistency: a sandbox is generated live and can drift; an authored story is reviewed before it is published.
- Visuals: Pominis stories have characters, scene images, and optional motion or video; a text sandbox centers on prose.
- Sharing: an authored story has a link that plays the same for everyone; a sandbox session is personal to the player.
- Your role: in a sandbox you play; in Pominis you write, and others play.
Who should stay with an AI sandbox
- You want to type anything and see what happens, without limits set by an author.
- You mainly play for yourself, as a solo roleplay or a creative warm-up.
- You enjoy the AI's surprises more than you want a particular ending.
- You want a story that keeps going for as long as you do.
Those are real strengths, and Pominis does not try to offer them. A reader of a Pominis story cannot type a new action, and the story ends where its author ended it.
Who Pominis suits better
- You have a story in mind and want players to experience it the way you intended.
- You want characters and places to look and sound the same from scene to scene.
- You want to share a link, see plays and likes, and let other creators remix it, if you allow that.
- You like making the choices more than making them up on the spot.
Bringing a sandbox session into an authored story
A good sandbox session is a useful first draft. Keep the parts that worked, such as the character who surprised you or the twist you did not see coming, and write them down as a premise and a short list of decisions. Bring that to VN Studio and ask for a short draft with those decisions as choices. You lose the improvisation and gain a story you can revise, test, and share.
Starting and publishing in Pominis is free; generating images and video uses credits, and the free plan includes daily credits.
