About AI Dungeon
What Is AI Dungeon
AI Dungeon is an AI text adventure game where a language model writes the world around your choices. You type what your character does or says, and the model answers with the next beat of the story. Latitude has run the product since 2019, and it works in a browser, on iOS, and on Android.
Most writing tools hand you a blank page and a cursor. AI Dungeon gives you a turn structure instead. You act, the AI narrates, and the plot keeps moving even when you have no plan. That rhythm is why people use it as an AI story generator for quick fantasy runs, for AI roleplay sessions, and for testing an idea before they write it properly.
The limits are real. The AI only reads part of the story at a time, so long campaigns lean on the memory tools to stay coherent. Images and extra context draw on a credit balance. Safety settings can block dark or mature turns depending on how you set them, and the AI Dungeon free tier gives you a shorter context window and a smaller model list.
Getting Started
- Create an account at play.aidungeon.com or install the AI Dungeon app on iOS or Android. Email sign up works, and a Google or Apple login saves a step.
- Pick a scenario from the featured list or start a blank adventure. Fantasy, sci-fi, mystery, romance, and survival setups all sit in the library.
- Choose a story model and set your context length. Higher plans unlock stronger models and longer windows.
- Write your first action in the Do, Say, or Story box, then keep going. Add Plot Essentials and story cards once characters and places start to repeat.

Key features
Open-Ended Story Generation
Every turn accepts a free text action, so you can attack, negotiate, lie, or walk away from the plot the game seems to be building. The model responds in prose and keeps the scene going. There is no win condition and no fixed ending, which makes it closer to interactive fiction than to a scripted game.
Memory System for Long Adventures
Five tools hold a campaign together: AI Instructions, Plot Essentials, Author's Notes, Story Summary, and the Memory Bank. You write short facts, and the system feeds them back with every action. It is the difference between a story that remembers the innkeeper's name and one that invents a new one each scene.
Story Cards for Characters and Places
A story card stores a name, a description, and trigger keywords. When those words appear in the story, the card's text enters the context. Ten cards cover a small cast and a few locations, and the AI starts referring to them correctly without repeating their descriptions in your own prose.
Custom Scenarios and a Community Library
You can publish a scenario with its own opening, instructions, and starting cards, then share it by link. The library holds thousands of player-made setups, from detective noir to slice-of-life school stories. Playing someone else's scenario is the fastest way to see what the engine handles well.
AI Image Generation
A blank See action, or a direct image request, generates artwork from your recent turns, plot essentials, and story cards. Your plan sets how many credits each image costs, and cheaper models cost less. It is a nice way to put a face on a character mid-session, not a replacement for a dedicated art tool.
Scripts for Custom Rules
Adventures support JavaScript scripts that hook into the turn cycle. You can add stat checks, inventory tracking, or a custom combat roll, and the state persists between actions. Most players never open the editor, and that's fine. For the ones who do, it turns a chat into something closer to a rules system.
Multiplayer and Shared Adventures
Multiplayer sessions let several players take turns in one adventure while the AI narrates between them. The host controls the scenario and settings. Public multiplayer on Voyage, Latitude's newer platform, is free, and it works without a paid AI Dungeon plan.
Pros and cons
Pros
- Zero setup: one click into a scenario and the story starts, with no prompt writing or configuration required.
- Deep memory tools: Plot Essentials, story cards, and the Memory Bank give you real control over what the AI remembers across a long campaign.
- Genuine freedom of action: any typed action is valid, so the story can leave the rails without breaking.
- Strong community library: thousands of published scenarios cover genres the official starter packs never touch.
- Cross-device continuity: the same account and the same adventure follow you from browser to phone.
Cons
- Context caps bite on long stories: the free tier sits at about 4,000 tokens, and even the top plan stops at around 32,000 before older text gets trimmed.
- Credits add a second meter: images and temporary context cost credits, so a heavy session can run through a monthly bundle.
- Model quality varies by plan: the cheaper models lose track of details sooner, and the good ones sit behind the higher plans.
- Safety filters interrupt some stories: dark, violent, or mature turns can get refused, which breaks the flow of a horror or grimdark run.
