cmd_c Overview
cmd_c is a powerful and seamless productivity tool designed for macOS users who want to elevate the quality of their writing effortlessly. It integrates directly into your workflow, allowing you to correct grammar, fix punctuation, and improve style in any application with a simple keyboard shortcut. By selecting a piece of text and pressing Command+C three times, you invoke a powerful AI model (from OpenAI or Anthropic) that instantly analyzes and refines your text, replacing the original with the perfected version.
This tool is built for universal compatibility, meaning it functions flawlessly across all your applications—whether you're drafting an email in Mail, collaborating in Google Docs, messaging in Slack, or taking notes in Notion. As long as you can copy text, cmd_c can enhance it. This eliminates the need to switch between apps or use cumbersome web-based editors, saving you time and maintaining your focus.
How to use cmd_c
Using cmd_c is designed to be incredibly intuitive and friction-free. Follow these simple steps to integrate it into your daily routine:
- Download and Install: Get the native macOS application from the official website. It supports macOS 13 and above, including both Intel and Apple Silicon Macs.
- Grant Permissions: The app requires Accessibility permissions in macOS to monitor keyboard shortcuts and paste corrected text.
- Configure AI Provider: You have two options. You can either subscribe to the premium plan for a built-in AI experience or connect your own OpenAI or Anthropic API key to use the app for free, giving you full control over usage and costs.
- Correct Your Text: In any application, select the text you want to correct. Press the Command (⌘) + C key combination three times in quick succession. The app will automatically process the text and replace it with the improved version.
