    "body": "CopilotKit is a React framework for adding AI copilot features directly into web applications. It provides hooks and components (useCopilotAction, CopilotPopup, CopilotSidebar, etc.) that let developers embed LLM-powered chat, suggestions, and agent actions into any React app with minimal setup. The framework has grown to 15,000+ GitHub stars and is backed by a funded company (CopilotKit Inc). The product site at copilotkit.ai has thorough documentation, SDK reference, and a growing set of templates. CopilotKit also introduced CoAgents \u2014 a framework for building multi-agent UIs with React that integrates with LangGraph and other agent orchestrators, giving frontend developers a way to expose agent state and actions in UI components. This is a VITAL product for the Hlido audience: it represents the infrastructure layer for building copilot-style AI products. The FADING (40) score is an artifact of testing the GitHub URL rather than copilotkit.ai. This was explicitly mentioned in the CLAUDE.md as a known v1 scorecard from before the v2 editorial gate.
