# AI game builder online, with your account online and the builder on your desktop > Sign up online, describe the game you want in the free desktop app, and the AI builds it into a real 2D or 3D project you own and can ship as a Windows or macOS build. - URL: https://www.summerengine.com/ai-game-builder-online - Keyword: ai game builder online - Related: https://www.summerengine.com/ai-game-maker An AI game builder online should not trap your game inside a tab. Summer Engine's AI works inside a free desktop app for macOS and Windows, with your account and credits online, and what it builds is a real project, not a demo that only lives on a host you do not control. It is a full engine compatible with Godot 4, so your game is yours to keep. Describe a 2D game and the maker builds the scenes, the gameplay, and the assets. It sets up sprites, a tilemap, a 2D camera, and 2D physics for you, then lets you refine everything in plain language while the game runs. When it plays the way you want, export a Windows or macOS build, publish on Steam or itch.io, and pay Summer no royalties or revenue share. A GDScript project also exports a web build that you publish on Summer Games. ## Build 2D games without an editor to learn first You describe the 2D game and Summer Engine builds it. Sprites, a tilemap level, a 2D camera, and 2D physics come configured for you, so you start with a playable game rather than a blank scene. The conversation is the interface, and a real project is the result. ## Real projects, not browser-locked demos Plenty of online makers keep your game on their site. Summer Engine is different: what you build is a standard 2D project compatible with Godot 4. You can open it, edit it by hand, and export it, so your work is never stuck behind a login. ## It makes the 2D art and audio Ask for sprites, tilesets, and backgrounds plus music and effects, and the maker generates and imports them as standard resources. You can swap or restyle anything by asking, so the game looks right without sourcing assets first. ## Iterate in plain language, then ship Tune the feel, add a level, change the art, or rework a mechanic, all by asking, and watch each change in the running 2D game. When it is ready, the builder exports a Windows or macOS build for Steam or itch.io. You own everything with no royalties. ## FAQ ### Is this online 2d game maker really online? The account side is. You sign up and manage credits online, and Summer Studio generates assets in a browser tab, but the AI builds and runs your game in the free desktop app. What it builds is a real project compatible with Godot 4, so unlike browser-locked makers, your game is yours to export and own. ### Do I need to install anything to start? Yes, the free Summer Engine desktop app for macOS or Windows. The AI builder lives there, so install it once after creating your account and start describing your game. ### Does it make 2D art? Yes. It can generate sprites, tilesets, and backgrounds plus audio, imported as standard resources you can swap or restyle by asking. ### Can I export the 2D game? Yes. Export a Windows or macOS build, publish on Steam or itch.io, and pay Summer no royalties or revenue share. A GDScript project also exports a web build for Summer Games. ### Is it free to start? Summer Engine is free to download and free to start, and the core engine is open source. You only pay for heavier AI usage as your 2D project grows.
