AI game engine that builds real 2D and 3D games

Summer Engine is an AI-native game engine. You describe the game and it builds the scenes, gameplay, and assets, on a real engine compatible with Godot 4 that you fully own.

An AI game engine should be a real engine, not a chat box bolted to a template. Summer Engine is a full 2D and 3D engine compatible with Godot 4, with AI built into the workflow: you describe a game and it builds the scenes, gameplay, and assets. What it builds is a standard project on your machine, not a demo locked in a browser.

You describe what you want and the engine builds a scene tree, gameplay scripts, and the art and audio to match, then you refine it all in plain language. Under the conversation is a complete engine you can open and edit by hand.

It is free to download and free to start, with paid plans only for heavier AI usage. Everything you make exports to desktop, web, and mobile, plus Steam, and you own it with no royalties.

A real engine, with AI in the workflow

Summer Engine is a full 2D and 3D engine, and the AI is woven through it: you describe a game and it builds the scenes, gameplay, and assets. That means you get the speed of describing a game with the depth of a real engine underneath, not a shallow generator that stops at a demo.

It builds gameplay, art, and audio

From a description the engine builds the scene and gameplay, and it can also generate the sprites, models, music, and effects your game needs, imported as standard resources. You can swap or restyle anything by asking, or edit it directly.

Compatible with Godot 4

Everything Summer Engine builds is a standard project, because it is compatible with Godot 4. You can open scenes and scripts, bring in existing Godot 4 projects, and edit by hand whenever you want. The AI workflow is the default, not a cage.

Own your games and ship them anywhere

What you make is a standard project with no lock-in, royalties, or revenue share. Export to desktop, web, and mobile, plus Steam, publish anywhere, and keep all of your revenue.
