Common Questions

We've got answers to some common questions!

What is a Copilot?

A Copilot is a trusted partner that lives in your application to help your users get things done. There are two main types, the Concierge and the Worker.

Concierge#

The Concierge Copilot understands your application's capabilities and full user context. It translates high-level user intent into actions by serving as an intelligent intermediary.

For example, our Banking Assistant implements Concierge Copilots to help users manage their (fake) banking needs.

Worker#

The Worker Copilot is a domain-specific agent that can help users perform their core work tasks. It serves as a partner to the user that is better at performing some tasks and worse at others. Ultimately, it amplifies your users to produce better work than they thought possible. This pattern is often used in backoffice copilots.

Think of the Worker Copilot as Cursor, Replit Agent, or Windsurf, but for any domain. For example, see our Open Researcher ANA.

How does it all work?

Great question! CopilotKit has three main components:

CopilotKit UI: The UI components that you use to build your Copilots and Agents.
CopilotKit Runtime: The runtime that you use to build your Copilots and Agents. This serves as the backend for your Copilots and Agents.
CopilotKit SDK: In more complex applications, you'll use the SDK to deeply integrate CopilotKit into your agents.

Can I use any LLM with CopilotKit?

Yes! CopilotKit supports most LLMs, including OpenAI, Anthropic, Google, and more. In addition, you can use any LLM that is supported by LangChain.
