AI Dungeon Alternative: A Free AI RPG and AI Text Adventure With a Cast and Quests

What is AI Dungeon?

AI Dungeon is Latitude's AI text adventure game. It launched in 2019 and, as TechCrunch recalls, became one of the first times many people interacted with generative AI. Its official site describes a free game where you create open-ended stories and guide every choice, online or in the app.

Adventures, Scenarios and input modes

Each playthrough is an Adventure, saved to your account. You start one from a Scenario: an opening prompt, Plot Essentials the AI should always know, an Author's Note for style, Story Cards and optional scripting. Scenarios can also be Character Creator starts or Multiple Choice branches, and the community has written thousands.

On each turn you choose a mode: Do for an action, Say for speech, Story for your own narration or See for an image. Continue, Retry, Undo, Redo and Erase move the adventure forward or back. Story Cards load characters and lore when their trigger words appear, the Memory System adds story summaries and a Memory Bank, and friends can join a multiplayer game with a code.

Tiers, content settings and platforms

AI Dungeon plays free without ads. The free Wanderer tier gets up to 4k tokens of context and 25 memories; paid memberships from $14.99 to $99.99 a month add models, context, memories and Credits. You need an account to play. Account-wide AI Safety Settings offer Safe (the default), Moderate and an age-verified Mature level. AI Dungeon runs on the web, the App Store and Google Play, and is officially English-only.

Voyage and the AI Dungeon beta

The AI Dungeon beta at beta.aidungeon.com is a testing environment open to every player, where new features arrive first (Latitude's guide). Voyage is Latitude's separate AI RPG platform, formerly called Heroes, which opened an expanded beta on April 21, 2026 (TechCrunch). Its Google Play listing describes stats and skill checks, co-op for up to eight players and a seat for a human dungeon master.

Why players look for an AI Dungeon alternative

AI Dungeon gives you enormous freedom: any action in any genre, a deep toolkit of Plot Essentials and Story Cards, a big Scenario library and multiplayer. Players looking for an AI Dungeon alternative usually want what it leaves to them:

• A cast that's already there. A Teasa Story starts with named Characters who have portraits, voices and relationships their creator wrote.
• Something to play toward. Quests list the creator's goals and complete when they happen in the story, each paying its Gold.
• A quicker first move. Your first 20 turns need no account.
• Another language. Teasa plays in English, Japanese, Korean, Simplified Chinese, Traditional Chinese, Spanish, Brazilian Portuguese, French and German.

AI Dungeon vs Teasa: two ways to play an AI RPG

Friends & Fables: an AI game master for D&D-style campaigns

Friends & Fables calls itself "the ultimate AI RPG platform for creators and adventurers": a text RPG inspired by Dungeons & Dragons, run by an AI Game Master named Franz. Franz narrates, applies the rules and reacts to your choices, with tactical turn-based combat based on D&D 5e rules, battlemaps, spells, monsters, inventory and travel. Its world-building tools cover maps, lore, NPCs and hand-made quests and one-shots, and you can explore thousands of player-made worlds. Parties of up to six players can adventure together, at the same time or at their own pace, on desktop, tablet and mobile.

Its pricing page, checked on 12 November 2026, lists a free tier with up to 25 turns per day, a turn being each message Franz sends, and campaigns of up to three players. Starter ($19.95 a month), Pro ($29.95) and Legend ($39.95) add unlimited standard turns, text-to-speech, bigger parties and monthly credits, with two months free on yearly plans; friends can join your campaign for free. Its terms require an account for most features and users who are at least 18.

Pick Friends & Fables for rules, dice-style combat and a tabletop group. Pick Teasa when you want the story and its people: a cast with history and personalities, scenes that answer what you write, and Characters you can keep talking to after the adventure.

Choose your own adventure with AI (CYOA)

Choose-your-own-adventure stories end each page with a choice: turn to one page to open the door, another to run. The Choose Your Own Adventure gamebooks have 270 million copies in print across 40 languages, and AI CYOA keeps the idea while removing the limit of two or three doors.

On Teasa, a Story plays like a CYOA book with every choice open:

• Pick a first line, or write your own. Some Stories offer Try one of these first lines; tap one the way you'd pick a door, or type anything else.
• Take the other door. Branch from here continues the Story from any earlier reply in a copy, so you can see what happens down the path you didn't take, and your original stays saved.
• Start from page one. Start new opens a fresh playthrough of the same Story, and a time skip jumps it ahead by days, months or years.
• Know where you're headed. Quests show the goals the creator wrote, so you can play toward an ending or ignore them and wander.

AI Dungeon offers Multiple Choice Scenarios, and Perchance's AI RPG lists choose-your-own-adventures among the stories it plays; both start from your prompt rather than an authored cast.

How Teasa plays as an AI text adventure

A Teasa Story gives you a text box and a world that answers whatever you write.

Your role, your words. Open a Story and read the opening scene. The input asks "What do you say or do?": type an action, a line of dialogue or both, and the asterisk button marks what you act out. The narrator and cast answer, each Character in their own voice.

Regenerate, steer or start over. Regenerate the latest reply, edit it, or use Tell AI what to change. Branch from here takes any earlier reply another way, and Start new on the Story page plays it again from the opening. Every chat and branch stays saved.

Quests you can see. Where the creator added them, progression quests arrive one at a time and open-world quests all at once. Tap Quests, the gold coin above the chat, to see your objectives and the Gold each one pays; Teasa marks a quest complete when it happens in the story.

A cast that keeps track of you. Relationship milestones record moments you earn with a Character. The Memory panel lists facts Characters have collected about you and lets you forget any of them; My Page → Privacy & data pauses collection.

Room for long adventures. Hojicha is the default chat style; Matcha (3 free replies a day), Earl Grey (with Teasa Pass) and Oolong (with Teasa Pass Pro) carry more memory. Teasa Pass adds live web lookup in DMs, ad-free play and priority replies (pricing).

A text-adventure turn on Teasa: a written example

This is a written example of how a Teasa adventure reads, not recorded output. You're the cartographer for a small hero party in a flooded ruin, and the Story's Quests list shows "Find a way past the drowned gallery."

You: I hold the lantern over the black water and count the pillars. "Oskar, the map shows seven. I count six."

Narrator: The light catches a ripple where the seventh pillar should stand. Something beneath the surface is turning, slow as a mill wheel.

Oskar: "Then the map's wrong, or the water's hiding it." He shifts his shield onto his shoulder. "I'll wade in first. If I go under, Mira pulls me out."

Mira: "I'd rather nobody went under. There's a chain on the far wall. Cartographer, is that on your map?"

Your next turn can be anything: pull the chain, drop a coin in the water, ask Mira about the flood. Don't like Oskar's answer? Regenerate it. Once the party is across, the quest completes, pays its Gold and the next objective appears.

Build your own adventure in Creator Studio

Writing Scenarios on AI Dungeon maps neatly onto Creator Studio. There's no importer, so carry your text across by hand:

1. Opening prompt → Opening. Write the first scene as ordered blocks, each with a speaker such as the narrator or a cast member.
2. Plot Essentials → Story. Add the premise, player role, world rules and private story direction.
3. Recurring characters → Cast. Create Characters with personality, speech style, voice samples and an AI-generated portrait. The D&D name generator names elves, dwarves, tieflings and the rest of a party, and the fantasy town name generator names the places they travel.
4. Story Cards → Blueprints. A Blueprint holds keyword entries for places, factions and history; connect up to five to a Story. The lorebook guide shows how to write entries that load when they should.
5. Add quests. Up to 20 objectives, in progression or open-world mode, with optional Gold rewards.
6. Play-test and publish. Test privately, then publish.
