AI Dungeon invented this category. Since 2019 it has introduced millions of players to a simple, powerful idea: type what you want to do, and an AI continues the story around your choices.

But if you're searching for alternatives, you've probably hit one of the reasons people go looking. So instead of asking "which app is best," the more useful question is: what kind of story do you actually want to play? A structured adventure? A character to talk to? A writing tool? A world you can step into and shape?

This guide compares eight platforms across pricing, memory, genres, and play style.

Full disclosure: we build Questner, one of the platforms on this list. We've tried to be straight about what each tool does best, including where others beat us, because the honest answer is that the right pick depends on how you play.

Why people leave AI Dungeon

AI Dungeon is still worth trying. For pure "type anything, the story follows" sandbox freedom, it remains remarkable. But three complaints come up again and again in community discussions.

Memory. The story works from a context window, and the size of that window is tied to your subscription tier, from about 4k tokens on the free plan up to 32k on the top tiers. As your adventure grows, older content falls out, and the tools that compensate (Memory Bank, Story Cards) put the maintenance work on you.

Pricing complexity. Paid plans currently run from $14.99/month (Journey) up to $99.99/month (Ultimate), sold in monthly credits and memory slots rather than anything that maps to playtime. It's genuinely hard to know how much play a tier buys until you've burned through credits yourself.

Drift. Because everything is improvised, long stories can repeat themselves, contradict earlier events, or struggle to reach an actual ending.

Different alternatives fix different pieces of this. Here's the field.

Quick comparison

1. Questner: playable AI stories across genres

Questner is an AI-powered interactive story platform where you jump into ready-made stories or create your own adventure from scratch. Yes, it's our product, so here's the honest pitch and the honest limits.

The core idea: you're not limited to picking from three dialogue buttons, and you're not staring at a blank chatbot either. Every story starts with a real situation. You wake up in a world you don't understand. You enter a cultivation sect with no power and too many enemies. You follow a clue that leads somewhere you shouldn't go. From there you type what your character does, says, investigates, or refuses. The story responds and remembers.

That middle ground is the whole design: more freedom than fixed-choice story games, more structure than a blank prompt.

What that looks like in practice:

• A library of ready-made stories across genres (fantasy, horror, mystery, isekai, cultivation, cozy slice-of-life, sci-fi, tycoon, sandbox), so you can start playing in under a minute instead of writing a setup prompt
• A custom adventure builder when you have a specific idea, plus the ability to publish your campaign for others to play. The best community-created campaigns get played, finished, and replayed by thousands of players, so Questner is as much a place to share your stories as to play them
• A growing creator community (r/QuestnerAI and Discord) where players swap campaigns, story moments, and building tips
• Simple, predictable pricing: 40 free messages to try it, a 7-day trial with 1,000 messages, and then $9.99 / €8.99 per month for 3,000 messages, or $99.99 / €89.99 per year for 36,000. Heavy players can add top-ups (3,000 for $9.99, 36,000 for $99.99) which roll over for up to 12 months. No tier ladder to decode, no credits that quietly map to nothing.

Where Questner is not the right pick: if you want tactical battle maps, strict 5e rules, dice mechanics, or multiplayer sessions with friends, Friends & Fables or Old Greg's Tavern below will fit you better. Questner is solo, text-based, and story-first.

Best for: players who want a ready-to-play interactive story, or a custom one, where typed choices actually shape the world Not ideal for: tactical tabletop simulation, strict rules-based play, or group sessions

2. Friends & Fables: tabletop-style 5e play

Friends & Fables is the closest thing on this list to a real tabletop session. Its AI Game Master, Franz, runs D&D 5e-inspired campaigns with character sheets, dice, maps and tokens, and a deep world-building suite with lore pages the AI actually reads during play. It supports parties of up to six players, and only the host needs a subscription.

The free tier limits you to a handful of AI turns per day. Paid plans are $19.95/month (Starter), $29.95/month (Pro), and $39.95/month (Legend), all with unlimited turns; the tiers mainly scale party size, context size, and monthly credits for premium models and image generation. Note it's still in early-access beta, and some players report memory struggles in very long campaigns on lower tiers.

Best for: solo or group players who want structured, rules-driven fantasy with maps and mechanics Not ideal for: players who want genres beyond D&D-style fantasy, or story-first play without rules overhead

3. Old Greg's Tavern: quick drop-in sessions

Old Greg's Tavern is built for zero-friction play: native iOS and Android apps, adventures that start in seconds, and multiplayer where up to six friends join free (only the host pays). World themes go beyond fantasy (dark fantasy, sci-fi, horror), and there's a community library of player-created worlds.

The trade-off is the pricing model. Instead of a flat subscription, you buy credits that convert into "rounds," one round being a full cycle of party actions and the AI DM's response. New players get a small number of free rounds; after that it's roughly $4.99 for a 5-credit pack. Heavy players in app-store reviews say costs add up, and some report the AI losing the plot in longer stories.

Best for: quick fantasy sessions, mobile play, casually adventuring with friends Not ideal for: long ongoing campaigns on a predictable budget, or players who want a broad ready-made story library

4. AI Realm: chat-first 5e play with built-in art

AI Realm sits between the tabletop platforms and the pure story ones. It's a chat-first AI Game Master built on D&D 5e SRD mechanics (races, classes, spells, inline dice, turn-based combat with an HP-tracking map), but the experience reads more like a choose-your-own-adventure novel than a virtual tabletop. Its standout feature is built-in image generation: character portraits and atmospheric scene art ship as part of the core product, even on the free tier.

The free tier is genuinely usable, at roughly 25-50 messages a day that replenish through the day, and paid plans start at $7.99/month for 500 messages, with higher tiers mainly buying more messages and image rerolls. The honest trade-off is memory: it relies on a player-maintained Notes system, and the platform's own guide says that if something isn't in your Notes, the AI will eventually forget it. Expect to spend a few minutes tidying notes every handful of sessions.

Best for: solo 5e-style play with visuals, on a generous free tier Not ideal for: players who don't want to manage the campaign's memory themselves, or anyone wanting genres beyond fantasy

5. Everweave: cinematic D&D-style stories on mobile

Everweave is a mobile-first text RPG (iOS, Android, PC) with an AI Dungeon Master and D&D-inspired mechanics. It auto-detects when your action needs a perception check or an intimidation roll, which is a nice touch. It's not combat-only either: you can lead armies or just run an inn and live a quiet medieval life. Players consistently praise its story memory, with details holding up thousands of messages into a campaign.

The catch is the message economy, and it's the platform's most common complaint. The free tier is 60 messages per month (not per day), which is one session's worth for many players. Subscriptions run $5.99 to $17.99/month (the top tier buys 1,000 messages), with extra packs from $2.99. Reviews frequently mention burning through allowances fast, and the game is still in early access with some rough edges.

Best for: cinematic fantasy stories on your phone, D&D flavor without rules homework Not ideal for: heavy players on a budget; there's no unlimited plan, and messages go quickly

6. NovelAI: writing, not playing

NovelAI is an AI-assisted writing tool, and a genuinely good one. Its Lorebook system keeps characters, factions, and world rules consistent across hundreds of pages, prose style is highly controllable, and stories are encrypted for privacy. The free Paper tier gives you 50 text generations to test it; paid plans are $10/month (Tablet), $15 (Scroll), and $25 (Opus), all with unlimited text generation.

The distinction that matters: writing a story and playing one are different experiences. In NovelAI you think like an author, caring about paragraphs, tone, and structure. In a story game you think like a character: what do I do next? NovelAI gives you a co-writer, not a game master. There's no scene framing, no consequences engine, no "the world pushes back."

Best for: fiction writers, worldbuilders, anyone who wants control over prose Not ideal for: players who want to open something and start playing

7. Character.AI: conversations, not campaigns

Character.AI is the biggest platform for chatting with fictional and original characters, and if your favorite part of storytelling is dialogue, like sparring with a villain or confiding in a mentor, it does that well. The free tier offers unlimited messaging, though it now runs ads mid-chat; the c.ai+ subscription ($9.99/month or $94.99/year) removes ads, speeds up responses, and improves memory.

But a character chat is one relationship, not a world. A full story needs places, events, consequences, more than one character, and the sense that things keep moving when you're not talking. Character.AI scenes tend to stay wherever the conversation goes, which is great for roleplay moments and thin for long adventures.

Best for: character-driven roleplay and dialogue scenes Not ideal for: complete adventures with plot, stakes, and a developing world

8. ChatGPT: the DIY option

ChatGPT can absolutely run an interactive story, and for people who enjoy prompting, that's part of the fun. You can have it build a world, narrate scenes, play NPCs, and adapt to anything you type. Free tier available; Plus is $20/month.

The catch is that you're the game designer and the player. You write the setup prompt, define the rules, remind it not to control your character, fix the pacing, and re-summarize events when the story drifts. General assistants also aren't tuned for game-master behavior; they tend to be agreeable, which means low stakes. It's hard to fail, and victories feel handed to you.

Best for: full control, custom scenarios, players who enjoy the prompting itself Not ideal for: anyone who wants to press play; the setup work is the price of the flexibility
