Cult UI
shadcn-compatible components plus 92+ AI agent patterns.
Cult UI started as another shadcn-compatible copy-paste collection and has become something more specific: a catalogue of interface patterns for AI products. Its own framing is that you use it to build your own component library rather than to adopt one.
At a glance

The AI agent patterns are the differentiator
This is the part no other library in this directory covers. Alongside the usual components sits a large collection of working agent interface patterns: research agents, data analysis agents, competitor intelligence flows, each with a live interactive preview rather than a screenshot.
If you are building a product where a user watches an agent work, the interface problems are genuinely unsolved: how to show a plan, stream intermediate steps, surface tool calls, handle a long-running task without a spinner. Cult UI is one of very few places addressing that directly.
Three ways in
Install a piece through the shadcn CLI, download an entire example as a Next.js application, or open it in v0 and iterate there. That last route is unusual and useful when you want to reshape a pattern rather than adopt it as written.
Choose it if
- You are building an AI product and need interface patterns, not just components.
- You already run shadcn/ui and want pieces that inherit your theme.
Look elsewhere if
- You need a conventional component library. This is a pattern catalogue with components attached.
- You need documented accessibility conformance per component.
