Wax vs CopilotKit
Wax: Wax provides persistent, searchable, and private on-device memory for iOS and macOS AI agents, eliminating the need for servers or cloud services. It integrates document storage, semantic search (HNSW), full-text search (BM25), and token budgeting into a single, crash-safe .wax file.; CopilotKit: CopilotKit is a React framework for embedding AI copilots, chatbots, and in-app agents directly into web applications. It provides UI components (chat interface, sidebar, textarea) and backend infrastructure for building agentic frontends — where AI can read and modify application state, take actions, and render generative UI. Supports LangChain, LangGraph, CrewAI, and custom agent backends.
