# Summer Engine: Build a Summer game with AI

> Install Summer Engine, create a Summer game in GDScript, add Summer SDK capabilities, test locally, and publish.

Summer Engine is the AI game engine for building a **Summer game**. Start in the editor,
write gameplay in **GDScript**, add the **Summer SDK** capabilities your game needs, then
test and publish from one documented path.

Describe what you want to build or change in natural language. Summer Engine can work across
your scenes, scripts, and assets while you review the changes in the same project.

**What makes Summer Engine different:**

* **One creator path**: Install, create, integrate the Summer SDK, test, publish, and update.
* **GDScript by default**: Start with the creator language used throughout these guides.
* **Portable source**: Your project stays yours. Familiar formats improve portability, but
  editor-version, import, plugin, native-extension, and export compatibility still need
  verification.
* **Project Intelligence**: AI understands your scenes, scripts, assets, and game logic
* **Reviewable Operations**: Changes go through editor APIs; review the diff and test the project after each operation
* **Privacy controls**: Pro accounts can enable Privacy Mode to opt out of training-data use

## For Pros and New Game Devs

Summer Engine is designed for everyone who wants to make games. It combines the ease of "vibe coding" with the power of a professional game engine.

### For Creators & Vibe Coders

* **Start in natural language**: Ask Summer Agent to draft scenes and GDScript, then review and test the result
* **Documented asset workflow**: Follow the asset-generation guide for currently supported providers, licensing, and quality tradeoffs
* **Learn as you go**: Watch how Summer Engine builds things to learn game development naturally
* **Focus on fun**: Skip the boilerplate and get straight to the gameplay

### For Professional Developers

* **Ship commercial games**: We shipped *Don't Pray* on Steam in 2.5 months using Summer Engine
* **Full Engine Access**: You have total control over every node and script
* **Code Quality**: AI writes clean, structured GDScript that follows best practices
* **Accelerated Workflow**: Handle tedious tasks instantly so you can focus on architecture and polish

Summer Engine removes boilerplate and accelerates iteration while giving you the option to dive as deep as you want. New models are evaluated before they are exposed; availability is documented instead of promised on a fixed schedule.
