DualClip: multi-slot clipboard manager for macOS

First project with macOS & Swift

I wanted to share DualClip, a native macOS menu bar app I’ve been working on.

While there are many great clipboard managers like Maccy or Paste, I found that most of them focus on "History"—searching through a vertical list of everything you've copied.

I built DualClip because I needed something that works more like a "Workbench." Instead of picking from a menu, DualClip gives you dedicated slots (A, B, and C) that you can access instantly via global hotkeys.

🚀 How it differs from history-based managers:

No List Selection: You don't have to break your flow to search or click an item from a list. You use ⌥⌘C to save to Slot B and ⌥⌘V to paste it instantly.

Atomic Paste: When you trigger a secondary slot, the app performs a high-speed "injection"—swapping the system clipboard, pasting, and restoring the original content in less than 50ms.

Parallel Workflow: Perfect for developers moving IDs and Emails simultaneously, or translators working with source and target text in two separate slots.

🔐 Privacy:

As a security enthusiast, I designed this with transparency in mind:

In-Memory Only: Clipboard data is stored strictly in RAM and is never written to disk.

Zero Network Access: The app has no network permissions. No telemetry, no analytics, no external communication.

🛠 Tech Stack:

Language: Swift 5.9+ / SwiftUI & AppKit Hybrid

The project is licensed under MIT, and I’d love to get some feedback or contributions from this community!

Thank you for reading my small project!
