π Overview
Quickfill bridges the gap between AI reasoning and functional user interfaces. Instead of the AI simply describing a dashboard or a tool, it builds and launches it instantly in your browser. No project setup, no npm install, no boilerplateβjust pure generative UI.
It uses a high-performance stack powered by Hono, Alpine.js, and Tailwind CSS to render lightweight, hot-reloading frontends directly from your conversation.
β¨ The "Generative UI" Workflow
The power of Quickfill lies in its ability to bridge local data with interactive frontends:
- π Analyze: Feed an Excel sheet, PDF, or image to your AI agent.
- π¨ Generate: The AI drafts a custom-tailored UI using Tailwind & Alpine.js.
- π Bridge: Use
mount_fileto expose your local data to the secure web environment. - π Launch: Use
render_interactive_uito pop open a live, functional dashboard in your browser.
π¦ Installation
Check out the USAGE.md for detailed installation and setup instructions.
π¨ Core Features
