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.
