Easel is a native SwiftUI macOS app that integrates AI-powered design and frontend development. It provides a local project library, design-system setup, AI chat (Codex or Claude), live web preview with point-and-click inspector, and slide tooling. Users can describe a UI, watch it build, and refine by clicking directly on the result. Key features include:
- Build prototypes with Codex or Claude
- Iterate by clicking elements in the live preview
- Reusable design systems
- Hand off to coding agents (Codex CLI or Claude Code CLI)
- Slide decks and animations
- Real file management and built-in code editor
- Menu bar integration and automatic updates via Sparkle
