What it does

CopilotKit allows founders to build generative UI for their applications using a variety of frontend frameworks such as React and Angular

When to use it

•Building a dynamic UI that adapts to user input and interactions
•Creating a conversational interface for a web or mobile application
•Developing a custom UI component that integrates with a larger frontend framework

Ready-to-paste prompt

Create a new generative UI component with `copilot.defineComponent('MyComponent', { template: '<div>Hello World!</div>' })`

Heads up: Make sure to configure the AG-UI Protocol correctly in your `copilot.config.js` file, as it is required for CopilotKit to function properly
