Overview of CMD-C

What is CMD-C?

CMD-C is a native macOS application designed to revolutionize how you handle text editing on your computer. Imagine selecting any piece of text in your favorite apps—like Slack, Notion, Google Docs, or even email clients—and instantly perfecting it with grammar corrections, punctuation fixes, and style enhancements, all triggered by a simple triple CMD-C keyboard shortcut. Powered by advanced AI models similar to those in ChatGPT, this tool integrates seamlessly into your workflow without disrupting your flow. Whether you're a software engineer drafting code comments, a product designer polishing UI copy, or anyone who types frequently on macOS, CMD-C eliminates the hassle of switching between apps for proofreading.

Unlike traditional grammar checkers that require pasting text into a separate interface, CMD-C works universally across any application where text can be selected and copied. This means no more context-switching; just select, triple-press CMD-C, and watch the AI transform your writing in seconds. It's particularly valuable for professionals in fast-paced environments where clear communication is key, saving time and reducing errors that could undermine your message.

How Does CMD-C Work?

At its core, CMD-C leverages powerful language models from providers like OpenAI or Anthropic to analyze and refine selected text. Here's a breakdown of the process:

  1. Selection and Trigger: Highlight the text you want to correct in any macOS app. Press CMD-C three times quickly—this acts as your universal shortcut for AI intervention.

  2. AI Analysis: The app sends the selected text to the AI backend (either the built-in service or your own API key). The model evaluates grammar, punctuation, sentence structure, and overall style, suggesting improvements that maintain your original intent.

  3. Instant Feedback: Corrections appear immediately, often with a side-by-side diff showing changes. You can accept, reject, or tweak them on the spot. Each correction comes with an explanation, helping you learn from the AI's reasoning—ideal for improving your writing skills over time.

  4. Privacy and Security: Data handling is a priority. When using your own API key, you're in full control; nothing is stored on CMD-C's servers. Even with the premium built-in AI, texts aren't retained, ensuring your sensitive information stays private.

This workflow is powered by accessibility permissions on macOS, allowing the app to monitor and respond to your shortcuts system-wide. It supports macOS 13 and later, including Intel-based Macs, making it accessible to a wide range of users.

Key Features of CMD-C

CMD-C stands out with features tailored for efficiency and customization:

  • Universal Compatibility: Functions in Slack for quick chat fixes, Notion for note refinement, Google Docs for document polishing, and beyond. As long as you can copy text, CMD-C can correct it.

  • Correction History: Access a log of past edits with detailed breakdowns. See the original text, modifications, and AI explanations side-by-side—great for reviewing patterns in your writing.

  • Flexible Pricing Options: Use it for free by connecting your OpenAI or OpenRouter API key (no credit card needed). Or opt for the premium license at just $2.99/month, which includes 7,000 corrections using a built-in AI model. This built-in option ensures privacy while keeping costs low.

  • Multi-Language Support: Handles any language supported by the underlying AI providers, from English to Spanish, French, and more—perfect for global teams.

  • User Testimonials: Real users rave about its impact. Dmitry Kuznetsov, a Principal Software Engineer, calls it a "game changer for daily work." Michael Rodriguez, a Software Engineer, praises its accuracy in Slack conversations. Khristina Kurelyak, a Senior Product Designer, highlights its seamless integration and value.

These features make CMD-C not just a tool, but an essential extension of your macOS experience, blending AI precision with everyday usability.
