What is an AI game maker?

An AI game maker is a tool that builds a game from your words. You type what you want, and the AI writes the game. Then you play it and ask for changes.

The name covers three types of tool. The tools do different work, so it helps to know the type before you pick one.

  • Prompt-to-game tools. You describe a game in a text box, and the tool makes a game that plays in the browser. Rosebud AI is this type.
  • Game engines with AI help. You build the game in an editor, and an AI helps with the logic and answers questions. GDevelop and Summer Engine are this type.
  • AI story games. The AI writes a text adventure while you play. AI Dungeon is this type. You make a story, not a game file.

We opened every page in the sources on October 31, 2026. These tools change their plans often. Check each pricing page before you start.

This post is on the blog of LifeSim, our game. LifeSim is not a game maker. We say where it fits below, and we say where the other tools win. For a wider look at the field, read our guide to games that use AI.

What is the best AI game maker in 2026?

The best AI game maker depends on what you want to make. For a fast browser game with no code, try Rosebud AI. For a game that you want to sell on Steam or in an app store, try GDevelop or Summer Engine.

Rosebud AI: a browser game from a text prompt

Rosebud AI calls itself an “AI Game Maker.” The home page asks you to “Describe your game below, or pick a template.” The page also lists a 3D game maker and a 3D model generator. It lists a 2D asset generator and a sprite sheet generator too.

Rosebud hosts your game for you. You get a link that you can share. Of the four tools here, Rosebud is the fastest way to make a game that a friend can play.

GDevelop: a no-code engine with AI help

GDevelop calls itself “the best open-source, no-code game engine.” It makes 2D and 3D games. You use its event system and AI to build games, and you can “Ask questions to the AI tutor.”

GDevelop can package your game “for desktops, the web, or mobile devices with a single click.” The editor and the engine are open source under the MIT license.

Summer Engine: an AI game engine on your computer

Summer Engine calls itself “The AI game engine.” It is a desktop app for 2D and 3D games. The home page says that “You own the code and assets you create.”

Summer Engine can prepare desktop exports. The page says that store accounts, signing, review, and submission are your job.

AI Dungeon: a text adventure that the AI writes

AI Dungeon calls itself “a free AI text adventure game.” You can play adventures from the community, or you can build a custom scenario. The result is a story that you play inside AI Dungeon. You do not get a game to publish.

Like text games? Our list of text-based games has more of them.

Is there a free AI game maker?

Yes. All four tools above have a free plan or a free tier. Each free tier has limits on the AI, and the limits are different.

  • Rosebud AI: free tier. The free plan gives a number of credits each week, with no credit card. You can create, play, remix, and share games. Code access, export, and commercial rights are not in the free plan.
  • GDevelop: free tier. The free plan says “Create your first game 100% free.” It gives a small number of AI credits each month. Paid plans give more AI use.
  • Summer Engine: free tier. The free app gives a few AI messages each day, with a monthly limit. You can also use the editor to create and export games by hand.
  • AI Dungeon: free. The home page calls the game free. We did not find a pricing page from the home page.

The pricing pages are in the sources below. The numbers change, so read them on the day that you sign up.

What does a free AI game maker not give you?

The free tier usually stops at export and at commercial use. On Rosebud, you need a paid plan to see the code. You need a higher paid plan to download the code or to sell the game. Plan for this cost before you build a big project.

Can I make a game with AI without coding?

Yes. You can make a small game with no code. The Rosebud tutorial says: “No coding experience is required for this tutorial.”

GDevelop also says that there is “No need for advanced programming languages.” It uses events instead of code. You pick a condition and an action, and the AI can help you set them up.

Where does no code stop working?

The AI does not always do what you ask. A change can break a part of the game that worked before. Then you must tell the AI what you did, what happened, and what you expected. The Rosebud tutorial gives this same advice.

Small games work best. An endless runner or a simple shooter is a good first project. A long role-playing game with many systems is much harder to build from prompts alone.

What kind of games can an AI game maker make?

Most AI game makers make small 2D and 3D games that play in a web browser. Some tools also make text adventures, and some engines export to desktop and mobile.

Browser games in 2D and 3D

Rosebud makes browser games and hosts them. Its tutorial example is a 3D endless runner. The player uses A and D to dodge, Space to jump, and a button to restart.

Desktop and mobile games

GDevelop and Summer Engine both make 2D and 3D games. GDevelop exports to the web, to desktop, and to mobile. On GDevelop, some targets, like iOS, need a paid plan.

Text games and AI characters

AI Dungeon makes text adventures. The AI writes the next part of the story after each of your choices. Rosebud also lists AI character chat in its plans. To design the people for your game, see our AI character generator guide.

Where LifeSim fits, and where it does not

LifeSim is our game, and it is not a game maker. It does not export a game, and it does not give you code. You cannot sell or publish what you make in it.

But LifeSim does one thing that people who search for an AI game maker often want. You start a new life from a short text. You can give a city and a story, and the AI fills the world. The people are AI characters with jobs, homes, and friends.

You then talk to them in your own words, and they remember you. You live one life, a day at a time. The map is the real Earth in 3D. LifeSim is free, with no ads, no subscription, and nothing to buy.

If you want to build and ship your own game, LifeSim is the wrong tool. Pick Rosebud, GDevelop, or Summer Engine. If you want to play a story that starts from your idea, read how to play LifeSim.

Do you own a game made with an AI game maker?

It depends on the tool and on your plan. Read the terms before you sell a game. Some tools keep the game on their servers, and some free plans do not let you sell.

Rosebud AI

The Rosebud pricing page does not say who owns the games. It does say what each plan allows. Full commercial rights start at the 10x Dev plan. With those rights, you can sell your games and assets, and Rosebud takes no commission.

Code download and a Windows build for Steam start at the Pro plan. The free plan keeps Rosebud branding on hosted pages. If you cancel a paid plan, you keep your games and links on the free plan.

GDevelop

The GDevelop pricing page does not say who owns the games. It says that companies with more than $50,000 USD in yearly revenue must use the Pro plan. For sales through app stores, the page says “Yes - get in touch.”

Summer Engine

The Summer Engine home page says that you own the code and assets that you create. It also says that you can build and export games with no royalties to Summer.

Selling an AI game on Steam

Steam asks you to tell it about AI content. The Steamworks Content Survey covers games that “used AI services during development.” You must describe that use “in detail.”

If the game makes AI content while it runs, you must also describe your safeguards. Valve wants to know “what kind of guardrails you’re putting on your AI.”

How do you make a game with Rosebud AI?

Describe the game, test it, ask for changes, and then publish it. These steps come from the Rosebud tutorial.

  1. Open Rosebud AI and type your game idea in the prompt box.
  2. Select Create, and sign in when the page asks you.
  3. Answer the questions from Rosie, the AI helper, if it asks any.
  4. Wait for the game to finish. The game then shows in Preview.
  5. Click inside Preview before you use the keyboard. Then test the controls and the score.
  6. Ask Rosie for one change at a time. Here is the tutorial example. “Make the starting speed slower so a new player has more time to dodge the first obstacles.”
  7. Play again to check the change.
  8. Select Publish in the editor toolbar. Check the game URL, and then select Publish again.
  9. Select Share, copy the link, and open it in a new tab to test it.

To release changes later, open Publish and select “Publish update.” Ask for one change at a time. Small requests are easier for the AI to get right.
