How to build agentic frontend applications with CopilotKit

CopilotKit is a framework that facilitates the integration of AI-powered features into React applications by allowing large language models to access the app's state and actions directly, eliminating the need for custom APIs or complex orchestration layers. This tutorial demonstrates building an AI-powered playlist builder using CopilotKit, showcasing its ability to make frontend state readable to language models, define executable actions, and design natural language interfaces on top of existing React components. The framework provides three core capabilities: readable state to give AI insight into the app's context, custom actions to execute tasks on behalf of users, and a chat interface for natural language interactions. By enabling the AI to interact meaningfully with the application's state and business logic, CopilotKit transforms AI from a passive chat layer into an active participant that can reason, act, and adapt in real time, thus forming a foundation for the next generation of context-aware, user-driven AI-powered frontend applications.
