Welcome to Summer

Summer is The AI Game Engine. We make game development as fun as playing games. No coding experience? No problem. Just tell Summer what you want to build.

​
Step 1: Download Summer

Getting Summer on your computer is super easy.
For Mac users:
  • Visit summerengine.com and click “Download for Mac”
  • Drag Summer to your Applications folder
  • Double-click to open (Mac might ask for permission - that’s normal!)
For Windows users:
  • Visit summerengine.com and click “Download for Windows”
  • Run the installer (Windows might ask for permission - click “Yes”)
  • Summer will be ready to go!
Summer is completely free to download and try. No credit card required!
  1. Open Summer → You’ll see a clean, friendly interface

  3. Create account → Use Google, GitHub, or email - whatever you prefer
  4. Back to Summer → The app will automatically log you in
We use your browser for security - Summer never sees your password!

​
Step 2: Build Your First Game

This is where the magic happens. Let’s create something awesome!
  1. Click “New Project” → Give it a fun name like “My Amazing Game”
  2. Choose a location → Anywhere on your computer is fine
  3. Click “Create & Open” → Summer opens with a chat window on the right
  4. Watch Summer think → It’s learning about your new project (takes a few seconds)
The chat window is where you’ll talk to Summer. Think of it as your creative partner!
Ready to see Summer in action? Try typing these:“Create a player character that I can move around”
  • Summer creates a character for you
  • Adds movement controls (arrow keys or WASD)
  • You can immediately test it by pressing the play button!
“Add some platforms to jump on”
  • Summer creates platforms in your game world
  • Sets up physics so your character can land on them
“Make the camera follow my player”
  • Summer adds a smooth camera that tracks your character
  • Now your game feels professional!
Don’t worry about being precise - Summer understands natural language. Just describe what you want!

​
Understanding the Interface

Summer looks like Godot because it IS Godot - with AI superpowers.
  • Multiple chat tabs → Different conversations for different features
  • Change review → See exactly what AI wants to change before applying
  • Sources → AI shows which files it’s reading from your project
  • Stage by hunk → Review changes line by line
  • AI commit messages → Generated from your changes
  • Conflict resolution → AI helps resolve merge conflicts
  • Play button gated → Runs tests before allowing play (can disable)
  • Headless testing → AI runs tests in background
  • Auto-rollback → If something breaks, AI can revert changes

​
What Makes Summer Different

Native Godot Fork

Not a plugin - Summer IS Godot with AI built into the core engine.

Project Intelligence

AI understands your entire codebase, scenes, and assets automatically.

Ops-Only Changes

AI can’t break your project - all changes go through safe operations.

Usage-Based Pricing

Pay only for what you use. Free tier for learning and small projects.
