AI Dungeon on Steam vs iOS/Android vs web: do my stories sync and is there any difference in features or performance?

On any platform—Steam, iOS, Android, or web—AI Dungeon is the same core game: you direct the story, the model improvises the world, and your account is the glue between all of it. Your adventures and scenarios are tied to your AI Dungeon account, not to a specific device, so your stories sync across Steam, mobile apps, and the browser version as long as you sign into the same account. The main differences you’ll feel are in convenience (controller/keyboard vs touch), offline behavior, and how fast or smooth things feel on your hardware, not in what stories you can play.

Quick Answer: Yes, your AI Dungeon stories sync between Steam, iOS, Android, and the web when you use the same account. The free Steam download now mirrors the free web/mobile experience, so the core features, models, and story content are effectively the same, with only minor UX and performance differences based on your device and connection.

Why This Matters

If you’re deep into a campaign—whether it’s a cozy Hearthfire slice-of-life or a Harbinger “prepare to die” gauntlet—the last thing you want is your progress trapped on one device. Knowing how AI Dungeon behaves across Steam, mobile, and web lets you:

• Grind through a dangerous dungeon run at your PC, then pick up the fallout on your phone.
• Experiment with new models or Phoenix features on desktop without losing access on mobile.
• Avoid nasty surprises around missing features or desynced saves when you switch platforms.

Key Benefits:

• Seamless story continuity: Your adventures, scenarios, and account data flow between platforms, so you can play wherever without starting over.
• Same core game everywhere: The free Steam client now matches the free web/mobile experience, so there’s no “second-class” platform.
• Flexible performance and comfort: Pick the platform that feels best for you—mouse/keyboard on PC, couch play on Steam Deck, or quick turns from your phone—without sacrificing your campaign.

Core Concepts & Key Points

Concept	Definition	Why it's important
Account-based sync	AI Dungeon ties your stories, scenarios, and purchases to your AI Dungeon account (email/login), not the device or app.	As long as you log into the same account, you can move from Steam to mobile to web and keep playing the same adventures.
Platform parity	The free Steam download is aligned with the free web and mobile experience, using the same backend, models, and account system.	You don’t have to choose “the best” platform to unlock content—your core access and models stay consistent.
Client vs server behavior	The UI you see is platform-specific, but the AI models, memory systems, and story data live on AI Dungeon’s servers.	Feature differences are mainly about interface and rollout timing (e.g., Phoenix beta), not separate model quality per device.

How It Works (Step-by-Step)

At a high level, AI Dungeon treats Steam, mobile apps, and the web like different doors into the same world. Here’s how that plays out.

1. Sign in with the same AI Dungeon account

   • On Steam, iOS, Android, and web, you sign into AI Dungeon using the same credentials.
   • Your account owns:
     • Stories (adventures you’re actively playing)
     • Scenarios and worlds you’ve created or bookmarked
     • Your subscription / Traveler access and AI model options
   • The apps are just different shells on top of the same backend.

2. Stories are stored server-side, not locked to the device

   • When you take a turn (type an action, see the AI’s response), that story state is stored on AI Dungeon’s servers.
   • That means:
     • You can start a run on Steam, then open the same adventure in your browser at play.aidungeon.io and keep going.
     • You can move from the legacy/production site to the Phoenix beta (beta.aidungeon.com) and back; data flows between Beta and Production.
   • If a feature is missing on Phoenix (for example, World Info or image generation while Phoenix is still in beta), you can still use it in the legacy version and your core story context stays intact.

3. Platform-specific UX and performance layers

   • The Steam app:
     • Now matches the free web/mobile experience: same Griffin baseline for free play, same model lineup by tier.
     • Gives you desktop perks—bigger screen, better keyboard, Steam overlay, and solid play on devices like Steam Deck.
   • The iOS/Android apps:
     • Optimized for touch and one-handed play—ideal for quick turns, commuting, or bed-time sessions.
     • Use the same backend as web, and just like Steam, they’re tied into your account.
   • The web version (play.aidungeon.io and beta.aidungeon.com):
     • Often gets Phoenix updates and experimental features first.
     • Lets you play without installing anything; good for jumping in from any machine.

   The AI model behavior, memory system, and story logic don’t care which client you use—they just read and write to your account and stories.

Common Mistakes to Avoid

• Using different logins and wondering why stories don’t sync:

  • If you accidentally sign up twice (e.g., one account on mobile, another on Steam), your stories and purchases will be split.
  • How to avoid it: always check you’re using the same email/login method on Steam, web, and mobile. If something’s missing, log out and confirm you’re on the right account.

• Assuming a missing feature on Phoenix means it’s gone everywhere:

  • Phoenix (the beta experience at beta.aidungeon.com) is rolling out features over time. Some legacy tools like World Info, Multiplayer, Scripting, Train the AI, image generation (See mode), and native mobile apps may be missing in the early beta builds.
  • How to avoid it: if you need a specific feature that’s not in Phoenix yet, switch back to the legacy site at play.aidungeon.io or the existing mobile apps. Your data flows between Beta and Production, so you won’t lose your stories.

Real-World Example

You kick off a brutal Harbinger run on your PC via Steam—classic high-stakes dungeon crawl where you know “GAME OVER” is on the table. You spend an hour weaving through traps, lose a companion to a bad roll, and finally reach a cliffhanger before bed.

Later that night, you open AI Dungeon on your phone (iOS/Android) and sign into the same account. Your Harbinger adventure is right there in your story list, mid-scene. You pick up the conversation, make a risky decision on mobile, and the AI continues the story with all your previous choices remembered.

The next day at work, you sneak a quick break in your browser at play.aidungeon.io (or check out the Phoenix beta at beta.aidungeon.com). Same account, same run: the party is still coping with last night’s bad call. You can continue the campaign, try another model like Muse for a more character-emotional arc, or hop into a new community Scenario—all without worrying which platform started what.

Pro Tip: If you’re experimenting with Phoenix features on web (like new model lineups or UI flows), keep your “serious” long-running campaigns accessible in the legacy site or mobile apps until every feature you rely on (World Info, Multiplayer, See Mode, etc.) is live in Phoenix. Your stories will still stay in sync.

Summary

AI Dungeon treats Steam, iOS, Android, and the web as different front-ends to the same adventure engine. Your stories sync across platforms as long as you use the same AI Dungeon account, and the free Steam download now mirrors the free web/mobile experience. The differences you’ll notice are in interface and hardware comfort, not in what models you can access or whether your favorite campaign comes along for the ride.
