AE AI Assistant

An Adobe After Effects CEP extension that brings AI-powered automation directly into the After Effects workflow. Generate expressions and ExtendScript code using natural language prompts.

Features

• Multi-Provider AI Integration: Supports OpenAI, Anthropic Claude, and Google Gemini
• Dual Generation Modes: Generate both ExtendScript (for automation) and Expressions (for property animation)
• Agent Mode: Autonomous execution where AI generates and runs code automatically
• Error Recovery: Automatic error detection and self-correction through AI feedback loops
• Context Awareness: Incorporates active composition state into code generation
• Streaming Responses: Real-time code generation display

Installation for Development

1. Install dependencies:

   npm install

2. Enable CEP debugging:

   • macOS:

     defaults write com.adobe.CSXS.11 PlayerDebugMode 1

   • Windows: Create registry key HKEY_CURRENT_USER/Software/Adobe/CSXS.11 with PlayerDebugMode = 1

3. Symlink extension to CEP extensions folder:

   • macOS: ~/Library/Application Support/Adobe/CEP/extensions/
   • Windows: C:\Users\<username>\AppData\Roaming\Adobe\CEP\extensions\

4. Restart After Effects

Development

• Run tests: npm test
• Build extension: npm run build
• Package extension: npm run package

Testing

The project uses Jest and fast-check for property-based testing:

npm test              # Run all tests
npm run test:watch    # Run tests in watch mode

Requirements

• Adobe After Effects CC 2020 or later
• Node.js 14+ (for development)
• API key from OpenAI, Anthropic, or Google
