What is the best free AI Dungeon alternative?

Worldtable is free to build, covers your first $1 of AI, and players never pay. After that a world runs on its builder's own AI provider, and that can be a model on the builder's own computer, which costs nothing beyond the hardware. Character.AI and Hidden Door both have free plans with no cap on messages or turns, and SillyTavern with a local model through KoboldCpp is free if you're happy to set it up yourself.

Is there an AI Dungeon alternative with real game rules?

Yes, a few. Worldtable keeps the map, travel time, fights, money and reputation in game code, and each world's builder picks its rules in plain words for the engine to enforce. Friends & Fables runs D&D 5e with turn-based combat on battlemaps. Latitude's Voyage advertises skill checks driven by your stats, skills and equipment.

Which AI Dungeon alternatives can I play with friends?

In Worldtable, a builder invites players into a shared world, and you can walk into a town and find someone else's character already there; players never pay. Friends & Fables takes a party of up to six, and the host's plan covers friends. Voyage lists co-op for up to eight players and public servers, and lets one player run the game as Dungeon Master.

Is there an AI Dungeon alternative that runs on my own model?

Worldtable does. A world can run on any OpenAI-compatible server, including one on your own computer: run the model with something like Ollama, LM Studio or KoboldCpp, put it behind a tunnel such as Cloudflare Tunnel or ngrok, and paste the tunnel's address into the world's AI settings. Your model writes the story, and Worldtable still keeps the map, the fights and the rules. If you want nothing at all to leave your computer, SillyTavern with KoboldCpp keeps everything local, but it's a chat front end rather than a game.

Which one writes the best prose?

That depends more on the model than the product. On Worldtable the world's builder picks the model, from anything on OpenRouter, any OpenAI-compatible provider, or their own. SillyTavern lets you choose too. NovelAI is built around writing alongside its own story models, with tools for steering the text, so it's the usual pick for people who care most about the words themselves.

Yes, it's written by Worldtable, and Worldtable is listed first. Everything said about the other products comes from their own sites, read on 9 October 2026, and each entry says who it suits better than us. If something is wrong or out of date, tell us and we'll fix it.

AI Dungeon alternatives in 2026: an honest list

AI Dungeon taught a lot of people that you can type anything and a story will answer. If you're looking for something else, here are seven products that are live today, ours first: what each one is good at, who pays for it, and where it falls short.

The short version

A fantasy world with rules that stay put, solo or with friends, on any model including your own: Worldtable.
D&D 5e with an AI game master: Friends & Fables.
More structure without leaving Latitude, in any genre: Voyage.
The best writing tools: NovelAI.
Playing in other people's worlds, fan-fiction style: Hidden Door.
Talking to characters rather than playing a game: Character.AI.
A chat front end you install and wire up yourself: SillyTavern.

AI Dungeon itself is still a good answer for some people: any genre, years of community scenarios, a choice of models and native phone apps. Our Worldtable vs AI Dungeon page goes through where it's the better pick.

The list

1. Worldtable (our pick, obviously biased)

A place to build a fantasy world and let people play in it. An AI narrates and voices every character, but game code decides what's true: the map, how long travel takes, who wins a fight, what you own, and what each character thinks of you.

Best for: players who are tired of the tavern moving and the villain forgetting them, and anyone who wants to make a world for friends. The World Studio drafts one from six questions; the builder then picks up to 20 rules, such as whether heroes die for good, that the engine holds the storyteller to.
Who pays: building is free and the first $1 of AI is covered. After that a world runs on its builder's own key, from OpenRouter or any OpenAI-compatible provider, paid to the provider directly. Players never pay.
Your own model: that provider can be your own computer. Run a model with something like Ollama, LM Studio or KoboldCpp, put it behind a tunnel such as Cloudflare Tunnel or ngrok, and paste the address into the world's AI settings. Your model writes the story; the engine still keeps the map, the fights and the rules.
The catch: fantasy only, and somebody has to build the world before anyone can play; worlds are private, and you get in by invite or by asking to join. Once the starter credit runs out, the builder brings their own key or their own model. Fights with several players don't have a battle map yet.

2. Friends & Fables

D&D 5e with an AI game master called Franz: tactical turn-based combat on battlemaps, spells and monsters, a party of up to six, and tools for building your own worlds, or thousands of player-made ones to explore.

Best for: groups who want D&D as they know it, with an AI running the table.
Who pays: a free tier with a daily turn limit; on a paid plan the host subscribes and friends play free.
The catch: it's 5e at heart. If you don't want classes, spell slots and turn-based tactics, that structure is in your way.

3. Voyage, by Latitude

A newer RPG platform from the team behind AI Dungeon. Characters keep memories and opinions of you, choices run through tabletop-style skill checks based on your stats, skills and equipment, and Voyage Studio lets you build worlds with characters, lore, quests, rules, maps and locations. Worlds come in several genres.

Best for: AI Dungeon players who want more structure without leaving Latitude, and groups: it lists co-op for up to eight players, public servers, and a mode where one player runs the game as Dungeon Master.
Who pays: free to download on web, iOS and Android, with paid tiers sold in the app.
The catch: it's young, and young platforms change fast.

Site: voyage.io.

4. NovelAI

An AI writing partner (“an AI that writes with you, not for you”) with its own story models and an anime image generator. Its Text Adventure mode treats lines starting with > as your character's actions, so you can play it like a classic text adventure.

Best for: people who care most about the prose and want fine control over how the story is written. Stories are encrypted on your side before they're stored.
Who pays: a free trial with a set number of text generations, then a monthly subscription; even the lowest tier has unlimited text.
The catch: it's a writing tool more than a game. Text Adventure mode is a way of prompting the model, not a rules engine, so nothing tracks your health, your coin or a map for you. Its pages describe no group play.

Site: novelai.net.

5. Hidden Door

“Where roleplay meets fan fiction.” You pick a world, add modifier cards that change the vibe and the storyline, make a character, and a Narrator builds the story around your choices. Writers can turn their own work into a playable world, and publish it.

Best for: playful, card-driven stories in other people's worlds, and authors who want their fans to play in theirs.
Who pays: a free plan with unlimited turns, a few worlds from the catalogue and one character conversation a day; a paid subscription lifts those limits.
The catch: the free plan caps how many worlds you can play, and its pages describe stories, cards and characters rather than tracked stakes like a map or a purse.

Site: hiddendoor.co.

6. Character.AI

Chat and roleplay with millions of characters made by its community, or make your own in minutes. Not an adventure game so much as conversations with characters, though plenty of people play out stories there.

Best for: talking to a particular character, and quick casual roleplay.
Who pays: free, with unlimited messaging and ads; paid plans (c.ai+ and the cheaper c.ai lite) add premium chat styles, more memory and fewer ads.
The catch: there's no game underneath: no map, inventory or dice, so stakes are whatever the chat says they are. Under-18s don't get open-ended chat with characters, and the company says its moderation can be conservative.

Site: character.ai.

7. SillyTavern, with a local model

SillyTavern is a free, open-source (AGPL-3.0) interface you install yourself for talking to language models (and image and voice models too). It connects to many back ends: paid APIs such as OpenAI, Claude, Mistral, OpenRouter and NovelAI, or a model on your own machine through KoboldCpp, which runs GGUF models from a single file.

Best for: tinkerers who want any model they like, full control over prompts, and everything kept on their own computer.
Who pays: the software is free. You pay an API provider for whatever you send it, or nothing at all if you run a model locally.
The catch: setup. You need Node.js to install it and a back end to talk to, and local models need a capable computer. It's a front end, not a game: there's no world or rules except what you write into it. If you have a local model and want a game around it, Worldtable can run a world on it through a tunnel.

Sites: sillytavern.app and KoboldCpp on GitHub.

How to choose

Every product here lets you type what you do and has a model write back. What differs is what the model is allowed to decide, and what holds the story together between scenes. Start from what bothered you about AI Dungeon, or what you liked.

You want freeform story: No map, no dice, the story goes wherever you push it. That isn't what Worldtable is for, and AI Dungeon is still the reference here; NovelAI if you want more control over the writing.
You want rules and consequences: Look for products where something other than the story model keeps score. Worldtable keeps the map, travel, fights, money and reputation in code, under rules the world's builder picks. Friends & Fables uses D&D 5e. Voyage uses skill checks.
You want to play with a group: Worldtable (as many players as the builder invites, sharing the same towns, and players never pay), Friends & Fables (up to six) and Voyage (up to eight, plus a Dungeon Master mode). Check who pays for the group: the builder, the host, or each player.
You care most about the prose: The model matters more than the product. On Worldtable the world's builder picks any model, their own included; SillyTavern lets you choose too. NovelAI is built for writing.
You want to use your own model: Worldtable runs a world on a model on your own computer through a tunnel, with the map, fights and rules still kept by the engine. SillyTavern with KoboldCpp keeps everything on your machine, as a chat front end rather than a game.
You want to build a world for other people: Worldtable is the one where your world gets a generated map with real distances, and rules you set in words that the engine enforces. Voyage Studio, Hidden Door and Friends & Fables also let you build and share a world.

If you want to see what “the engine enforces it” means in practice, the docs mark, for every mechanic, whether code holds it or the storyteller is only asked to.
