| Summary | Codeium (later rebranded Windsurf) built an AI coding assistant and AI-native code editor that provides autocomplete, chat, and multi-file agent-style editing workflows for software developers. The company was acquired by Cognition AI in July 2025 after Google separately hired its founding team and licensed certain technology. | AI SDK UI is Vercel's open-source frontend toolkit providing framework-agnostic hooks (useChat, useCompletion, useObject) for React, Vue, Svelte, Solid, and Angular that handle streaming chat state and generative UI interactions. It is the UI layer of the broader Vercel AI SDK, enabling developers to build AI-powered chat and completion interfaces without managing low-level streaming logic. |
