Manual download

Download the latest release, unzip, and drag CopyCopy.app to your Applications folder.

You copy things all day.
Then you work around your clipboard.

  • Paste from a webpage and manually clean the formatting
  • Open Google Translate in a separate tab
  • Rewrite that email draft one more time before sending
  • Read a long article and wish someone would summarize it
  • Copy code and wonder what it does

Built for this

On-device AI

Summarize, translate, rewrite, and explain code using local GGUF models with Metal GPU acceleration. No API keys, no cloud.

Learns from you

Remembers which actions you use and when. The AI suggests smarter follow-ups based on your patterns over time.

Pipeline actions

Chain multiple steps: Markdown → Summarize → Translate. AI picks the best follow-ups — skips useless ones automatically.

Multiple models

Choose from LFM, Gemma, or Qwen models. Download from the menu bar. Switch instantly. Metal GPU accelerated.

Extensible

Create custom SKILL.md files with your own prompts or tool calls. Override any built-in skill.

Native & lightweight

SwiftUI menu bar app with frosted glass UI. No Electron, no web views, no background daemon.

Your clipboard stays yours

CopyCopy runs entirely on your Mac. AI processing happens on-device using llama.cpp with Metal GPU acceleration. Nothing is sent to any server, ever.
