fynk Refactors In-App AI Assistant with CopilotKit and AG-UI Protocol, Cutting 11,000 Lines of Code
We replaced 11,000 lines of AI chat code with CopilotKit and AG-UI
AI guide
The fynk team shared their experience refactoring their in-app AI assistant using CopilotKit and the AG-UI protocol, successfully replacing roughly 11,000 lines of proprietary chat protocol and state machine code. Because fynk runs on Vue while CopilotKit natively supported only React, the team used coding agents to build a 62,517-line Vue port, which was upstreamed and merged as @copilotkit/vue.
Why it matters
