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

How it works

1

Select

Select text, a URL, code, logs, a file, or anything else you want to act on.

2

Copy Copy

Press ⌘C twice. CopyCopy reads the clipboard context and opens near your cursor.

3

Pick an action

Choose the best ranked action, then keep going with contextual follow-ups.

Context-aware

It knows what you need

CopyCopy reads the content and the app it came from, then ranks the best next action. Hover a card to see the result.

Built for this

On-device AI

Summarize, translate, rewrite, and explain code using a local Gemma 4 E2B GGUF model 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: Smart Markdown → Summarize → Action Items. Heuristics show instant follow-ups; local AI can reorder them.

Action harness

Detects clipboard type, entities, and source app; ranks matching skills with usage history; executes only what you choose.

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.

No telemetry No clipboard history No network calls Open source
