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.
A polished space for notes, tasks, and documents that follows you across every device.
Embed tasks directly inside documents and pair them with a calendar view so planning and execution stay connected.
Choose the structure that matches your thinking — separate work and personal spaces, nested folders, tags, or database-style collections.
Draft, refine, rewrite and summarize content without leaving the document.
Apps for iPhone, iPad, Mac, Vision Pro, Windows and Android with local access when you're offline.
