affectUI compared
affectUI is for the product side of an AI app – chat, agents, approvals, dashboards – as finished components that need only React. shadcn/ui gives general primitives, AI Elements and assistant-ui focus on the chat and its connection to a backend, and Aceternity UI and Magic UI on animated landing pages. Most of them work together: they install through the same shadcn CLI.

Questions
Does affectUI replace shadcn/ui?
No. shadcn/ui covers general primitives such as buttons, dialogs and inputs; affectUI covers the AI-specific parts. They install through the same CLI and work side by side.
Which library is best for an AI agent UI?
For chat wired to a backend, AI Elements or assistant-ui. For agent views beyond the chat – traces, agent trees, approvals, costs – and a finished look without Tailwind, affectUI.
Which one for a landing page?
Aceternity UI or Magic UI for big animated sections. affectUI has a smaller set of illustrations and motion effects that match the product.
