Infinite Worlds Alternatives (2026): 4 Options Compared

Maybe you built a dozen worlds in Infinite Worlds and realised you would rather play one properly. Maybe your credits ran low halfway through a good story. Or you simply want to see what else is out there before you buy more.

We make Mythora, one of the options below. This guide is organised around the adventure you want next, and it says plainly where Infinite Worlds is still the better fit.

What Infinite Worlds does well

Infinite Worlds is a browser-based AI adventure game made by Friendly Fox Games. Its homepage promises that you can try to do anything in a scene, and that your character might fail. The story is told with illustrations.

Its standout feature, in its own words, is that you can create your own worlds in minutes and share them with friends. Want a zombie rom-com or a gritty detective story? You describe the setting and play inside it.

On cost, the FAQ (linked from the homepage footer) explains that play is paid for with credits you purchase. It also runs a bonus-credit scheme: if someone follows your shared link and plays a world, you earn a share of the credits they spend, which you can use to play or, past a threshold, cash out. If you enjoy making worlds that other people play, few products reward that so directly.

AI Dungeon: endless community adventures

If what you loved was the "try any premise" feeling, AI Dungeon is the obvious next stop. Its homepage calls it a free AI text adventure game that you can play online or in its app. Players can also create and publish their own scenarios, the starting templates other people pick up and play.

Choose it when you want variety, and the freedom to make a premise of your own now and then.

Questner: campaigns with your own rules

If the building side is what you will miss most, Questner is worth a look. Its FAQ says players can create their own campaigns, worlds, characters and rules, then share them by link or publish them for others to find. It starts with 40 free messages and a 7-day trial, then a paid subscription from $9.99 a month.

NovelAI: the writer's chair

Some players realise they enjoy shaping the prose more than playing the scene. NovelAI is built for that. You steer the text line by line and keep notes about your characters and places in its Lorebook, so they come back when they are mentioned.

It is less of a game and more of a writing partner. If you are leaving NovelAI too, see our NovelAI alternatives guide.

Mythora: a world that is already there

Picture a monster hatching in the dark of a dungeon floor, weak and hunted, with every kill a chance to grow into something stronger. You do not design the dungeon. You wake up in it and decide what to try first.

That is the idea behind The Hollow Spire, a monster-evolution LitRPG world in Mythora. You pick a world, create a character and play by typing what you do or tapping a suggested action. Your progress is saved, so the next visit picks up the same character in the same place. Worlds are shared with other players, although you follow your own character's path rather than joining a live party.

A favourite moment for many players is naming a technique or a power and watching the story respond to it. The world still pushes back: a bold move can fail, and the next scene carries the consequences.

Other worlds to start with:

• The Mortal Dao for a cultivation climb from nothing.
• Manafall for modern system-apocalypse survival.
• Dead Signal for a modern zombie outbreak, if you liked the post-apocalyptic worlds you built yourself.
• Crowns of Atheria for isekai fantasy.

Mythora is free to start with action energy that refills, plus optional purchases. It runs in the browser and also has apps for iPhone, iPad and Android. More on the genre in AI LitRPG games that keep your progress, and on how shared worlds work in shared-world AI RPGs, explained.

Where Infinite Worlds is the better fit: if you want to invent your own world from a few lines, play it with illustrations and share it with friends, Infinite Worlds is built for that and Mythora is not. Ordinary Mythora players cannot write and publish their own worlds; you play in worlds that already exist.

How to test an alternative in one evening

1. Pick one character idea you already care about, such as the scavenger in your zombie world or the detective in your noir city.
2. Play ten actions in the new product without restarting.
3. Close it, come back the next day, and see whether the story still knows who you are and what you were doing.
4. Check the price only after you know whether you wanted to come back.

That last step is the honest test for any of these games.

FAQ

Is there a free Infinite Worlds alternative?

Several start free. AI Dungeon describes itself as free to play, Questner starts with 40 free messages, and Mythora is free to start with action energy that refills, plus optional purchases. Check each official site for current terms.

Which alternative is closest to Infinite Worlds?

If you mostly built worlds, Questner or AI Dungeon, since both let players create and publish their own adventures. If you mostly played, and want one character to keep growing in a world with real pushback, Mythora.

Can I bring my Infinite Worlds world with me?

Not directly. Each product stores stories its own way. The easiest move is to bring your character idea and the one goal they care about, then start fresh. In AI Dungeon or Questner you can also rebuild your setting by hand.

Do any of these remember everything?

No AI story is perfect over a long campaign. Try a short run first, and see our guide on what to do when an AI story forgets.
