apfel-clip

apfel-clip is a macOS menu bar application that applies AI transformations to whatever you have copied to your clipboard. The workflow is simple. You copy some text, press a global hotkey, pick an action from the menu, and get back the transformed result. Everything runs locally on your Mac with no API keys, no network calls, and no data leaving your device.

The app sits quietly in your menu bar until you need it. When you invoke it with the default shortcut of Command Shift V, it detects what kind of content you have copied and shows contextually relevant actions. Text might get options for grammar correction, translation, or summarization. Code snippets might show actions for explanation, formatting, or converting between languages. JSON might offer pretty printing or schema extraction. The app figures out what you are working with and adapts.

Privacy is the core design principle here. A lot of AI clipboard tools send your text to cloud services, which is a non starter if you are copying sensitive code, credentials, or confidential documents. apfel-clip processes everything on device using local models, so nothing ever leaves your machine. For developers, writers, or anyone handling private information, this matters more than raw capability.

Beyond the built in actions, you can create your own custom transformations. If you find yourself repeatedly doing the same kind of text manipulation, you can define it as an action and trigger it with the same hotkey workflow. The app also keeps a persistent history of your transformations so you can go back to previous results without running them again.

The interface includes favorites and reordering so you can surface your most used actions quickly. There is also an auto copy option that puts the transformed result directly back on your clipboard, saving you the step of manually copying the output. These small conveniences add up when you are using the tool dozens of times a day.

apfel-clip is completely free with no subscription model or premium tier. It is also MIT licensed and open source, so you can inspect the code, fork it, or contribute improvements. The developer has signed and notarized it with Apple, which means it installs cleanly without the security warnings you get from unsigned apps.

The target audience is macOS users who want quick AI powered text transformations without privacy concerns. Writers use it for grammar checks and rephrasing. Developers use it for code explanation and formatting. Anyone who regularly copies text and wishes they could quickly do something to it before pasting will find value here. The limitation is that it only runs on macOS, so Windows and Linux users will need to look elsewhere.
