AI Dungeon: You Type One Move, the World Rewrites the Scene

Bottom line: This is an account-gated English text adventure. The free tier covers the basic loop: you type the next action, it continues the world. There is no official ending, and it is not a history source. Treat it as an improvised dungeon master.

One-minute overview

• What you do: Pick a setting, then enter one action or line of dialogue each turn so the system can continue the story.
• First move: After you register, press Play, use Quick Start, then write one short action with Do.
• Where the AI sits: Official getting-started help describes a neural net that reads recent story text and guesses which words are likely to follow, which is how rooms, characters, and surprises appear.
• Is there an ending? No campaign finish line. Adventures are stored in My Stuff and can be rejoined later.
• Language: The interface is English. Chinese input can work; community scenarios are usually richer in English.

Why it’s interesting

A classic text adventure is a booklet of three buttons. AI Dungeon turns the next sentence into a game turn. Official help calls it a roleplay and interactive-story tool: tap Take a Turn, use Do for actions, Say for speech, or Story to push the plot yourself. The system writes the following scene from the setting and the text so far.

The more interesting way to play is to set a small goal and then interrupt it. Open a door honestly, then go looking for coffee, and see whether the narrator can keep cause and effect intact. Official help also says the AI is not always perfect. Do not wrestle a derailed paragraph — Retry rewrites the latest output, and several retries build a Retry Stack so you can pick a usable version. Edit lets you fix a wrong name or a broken detail; the help pages say the model does not know you edited, so it treats the corrected text as if it had written it that way.

Community scenarios live under Discover; custom setups also work. In every case, generated text is not a record of real events or professional advice. See can add an illustration without changing the story. Image models may spend Credits; check the cost shown in your account.

How to try it

First minute: complete one turn

1. Open the original link on this page and create a free account. Official help says the models run in the cloud and adventures are stored on the account, so login is required. Offline play is not offered.
2. Press Play, use Quick Start, pick a setting, character, and name, and let the system write an opening.
3. Tap Take a Turn, switch to Do, and write one short action. Official advice is to be specific; a line like You go in. leaves too much of the next beat to the model.
4. For the first try, use: open the wooden door and look around the room.
5. If the result derails, loops, or simply is not what you wanted, press Retry before pasting a wall of backstory.

You can also use [play.aidungeon.com](https://play.aidungeon.com/) or the official iOS / Android apps. Keep Safe for the first session.

English interface: the words that matter

First small goal: leave a room in eight turns

This route exists so you learn short actions and retry, not so you write a novel.

Stop before opening a giant community scenario. Try yanking the story somewhere unrelated: cave one turn, coffee shop the next. Official copy says anything you can type, it will try to continue. If it cannot, undo. That is cheaper than a traditional reload.

Three ways to keep going

1. Stress-test the host. Every third turn, lie, switch sides, or send a fantasy quest into an office. Watch whether it answers with common sense, genre habit, or invention.
2. Set a 20-minute goal. Find a key. Leave the castle. Get through without a fight. Short goals make forgetting obvious. The free tier has less context, so long adventures drop details sooner.
3. Use memory tools only when it starts forgetting. Official slots are Plot Essentials for facts that should always stay in context, Story Cards for keyword-triggered people and places, Memory Bank for retrieved summaries, and Author's Note for tone. Skip them on the first session.

Common stuck points

• The first line is too empty. Replace “go in” with which door and what you look at.
• It forgets a name. Edit, then put one sentence in Plot Essentials.
• The same paragraph loops. Retry a few times, then undo two steps and rewrite your previous line.
• A “content not supported” popup is the official SCIM filter (sexual content involving minors). Do not keep probing.
• An in-story “I can’t continue” is, per official help, often a model hallucination. Retry first.
• Retrying every sentence on a paid model spends generation. Official advice: if it is mostly fine, edit the details.
• Undo may not survive a refresh. Use Erase or Edit after a reload.
• Chinese scenarios are thinner. You can type Chinese; Discover is still mostly English.
