@shadcn Okay, I get it now. I love Copper. I find myself highlighting things and double-tapping Left Shift to save them instead of trying to remember them, or bringing Copper to the front, jotting down a thought, and getting right back to what I was doing. It’s so quick and effortless 🫶🏻

One more use case I found is just persisting some information.
You're filling a form, and once you click the button, you'll never see that data again, but what if you need to have it? You can paste it to Notes, etc, but just Shift + Shift and it's persisted without additional clicks; you can read it again later.
Same for code, really huge when working with agents

If you have a large registry, we now forward search params so you can implement dynamic search and return paginated results.
(This is opt-in. Static registries keep working as-is)

Rich text article sections in Initium App are now styled by @shadcn typeset, replacing the old prose utility.
Genius lies in simplicity. I got Copper 1-2 days ago, and it’s already made managing AI agents (and my emails) much easier. In my words, it’s a memory management system for "humans" working with AI. When you start using it, you can tell how deeply @shadcn understands the problem. Seriously, hats off.

If you're adding a navigation rail to your chat app, consider the UX of ChatGPT Web. They do this right.
- It shows the whole conversation, not one message at a time.
- You see what you asked before and what comes next. Context at a glance.
- It has one focus target. You assign it a shortcut.
- It is a list so you can add a search field and arrow keys for navigation.
- It stays open while you jump between messages.

A registry for code. "capabilities" if you will.
Prediction: the @shadcn registry becomes the standard way AI agents get UI components.
Think about what an agent needs: readable open code, semantic tokens it can re-theme, one CLI command to install, a JSON index it can search.
The registry already does all four. My agent installs blocks, styles and even its own skills from one namespace, mid-build, without me touching anything.
We got the package manager for AI-built frontends.

years later, shadcn is a protocol for distributing any kind of code.
in hindsight, it's surprising that we used to hide all third-party code away in gitignored folders.
Amazing Amazing launch yesterday.
Best part is how many of you have said this is exactly what you’ve been looking for. Happy to see this click right away.
Already working on some fun new features. More soon

Launching Copper, a Mac app for capturing things you want to keep and prompts you want to try next while working with AI.
The more I use AI, the more I find myself collecting little things I don't want to lose.
You're in ChatGPT and think, "I'll need this later," but you don't want to stop what you're doing. Then you're in Claude. Cursor. Chrome. Back to ChatGPT.
Before long, you've got little things scattered everywhere. An answer you want to keep. A link. An idea. Or three follow-up prompts before the current one has even finished generating.
I had this problem, so I built Copper.
Copper combines the useful parts of a to-do list, a clipboard, and a scratchpad. It's built specifically for AI-assisted work. It sits next to where you work and is always one shortcut away. It works with all your AI apps, terminals and browsers.
Whenever I find something worth keeping, I capture it. If I think of a few prompts while the AI is still responding, I type them into Copper. Then I send them back into ChatGPT, Claude, or Cursor and check them off as I go.
Copper is local and private. It doesn't sync anything, doesn't collect anything, and doesn't need an account.
I've used Copper every day for the past few months. It has completely changed how I work.
If this feels like something you'd use, it's $39. One-time purchase.

specific knowledge = sick apps
god damn it it’s exactly what I need and have been thinking about the shape of.
it’s so clean
Copper now lives rent free on my Mac, I can see myself abusing this.
Pretty incredible that the same system built to ship a button can now distribute an agent.
The big idea of @shadcn registries was that dependencies can be both "vendored" (in your repo) and managed (they can be updated automatically).
This is amazing for AI-based development because the agent can just see the implementation. Security is better because the code isn't hidden in some ephemeral directory. And if the code isn't quite right it can also change it right there.
We're adopting this model for @evedev_ extensions and I believe it's a perfect fit.
Get that extension from the vendor of your choice. And have your agent change it to your liking.

very beautifully made, so hyped to try this
Press Shift Shift to capture anything from anywhere.
Probably the fastest purchase I’ve ever made.
The simplicity yet usefulness of this is what makes it genius.
Definitely copping this, no pun intended 🫡
I've been using it for the past few days, and it's already part of my workflow.
As always, the king of UX showing everyone how it's done.
Just press Shift + Shift, capture anything from anywhere! AI chats, Discord, X, docs...
It instantly becomes part of your AI workflow.
Such a simple idea, executed perfectly.

npx shadcn create is a great way to start a react project. It's just react + tailwind + a component library + your framework.
Raycast is my favorite example when people ask me about designing keyboard shortcuts.
Most of us try to make shortcuts memorable. T is for theme, so I'm going to make option+t toggle theme.
That's fine. But you need to consider user's hand placement. Are they using your app one-handed, or are both hands already on the keyboard (like right after launching Raycast)? Which common actions a user might be need both a pointer and a keyboard to do?
Raycast gets this. Really well.
The shortcut should meet the hand where it already is.
