Open-source frontend stack for building AI agents and copilots inside your own product
Ship a working copilot UI in minutes with drop-in components for React, Angular, Vue, iOS, and Android, or go fully headless for total control over rendering.
A general-purpose bi-directional link between your app and any agent backend, with integrations for the OpenAI Agents SDK, Claude Agent SDK, LangChain, Google ADK, AWS Strands, Mastra, and many more.
Agents return real UI — charts, forms, tables, and approval prompts rendered with your own design system on the same screen the user is already working in.
Let agents read and write application state, call your frontend functions, and pause for human approval before sensitive actions are executed.
Preview Tailwind CSS and React output inside ChatGPT as you build
Renders HTML that uses Tailwind utility classes in a preview pane beside the ChatGPT conversation, so styles appear correctly without leaving the chat.
Interprets React output, including createRoot render patterns, and shows the resulting UI in the same live preview area.
Bundles curated prompts for Tailwind CSS page and component generation plus React component design, cutting the prompt-writing work on repeat tasks.
Regenerating a response refreshes the preview in place, keeping the design-prompt-redesign loop entirely within ChatGPT.
