What customers are saying

Teams around the world are building the future of AI-powered applications with CopilotKit.

Docusign is partnering with CopilotKit to enable in-application agentic experiences that bring the power of AI into our applications, improving workflows and clarifying customer questions. The CopilotKit SDK has accelerated our development processes and enabled us to help our users accomplish their tasks more quickly and with more confidence. The CopilotKit team has been a delight and has consistently responded to our concerns and feature requests.

Mark Peterson, VP of Software Engineering

Docusign

Docusign

CopilotKit has been a valuable addition to our stack. The AG-UI architecture lets us cleanly decouple our agent framework from the frontend, so we can evolve each independently. The pre-built component library saved us from rolling our own, and the agent's ability to drive the UI directly has let us build experiences that go well beyond a standard chatbot. Their support team has also been consistently responsive whenever we've needed help.
