CMD-C.app

CMD-C.app is a native macOS utility that brings advanced AI-powered text correction directly into any application's workflow. Its core value proposition is eliminating the friction of switching between writing and editing tools, allowing users to polish grammar, punctuation, and style instantly wherever they type. By operating as a system-wide service, it turns the simple act of copying text into a powerful editing command, seamlessly integrating professional proofreading into the user's existing habits.

Key features: The tool performs comprehensive text analysis, fixing common grammatical errors, adjusting punctuation for clarity, and suggesting stylistic improvements to enhance readability. For example, it can correct subject-verb agreement, replace repetitive words, adjust comma placement, and rephrase awkward sentences. It works with rich text, preserving formatting like bold or italics, and allows users to review and accept or reject each suggestion before applying the final correction to their document.

What sets CMD-C.app apart is its unique system-level integration and effortless activation via a triple-press of the Command-C keyboard shortcut. Unlike browser extensions or standalone apps, it requires no manual text pasting into a separate window, functioning directly in email clients, word processors, code editors, and even design tools. It leverages on-device processing for privacy where possible and connects to cloud AI models for more complex corrections, offering a balance between speed, power, and data security.

Ideal for professionals, students, and non-native speakers who write extensively on macOS and need to ensure error-free, polished communication without interrupting their creative flow. Specific use cases include drafting emails, writing reports, preparing academic papers, creating content for blogs or social media, and composing important messages in business or customer support contexts where tone and accuracy are critical.

The service operates on a freemium model. The core functionality is available for free with generous usage limits, while a Pro subscription unlocks unlimited corrections, priority processing, and support for specialized writing styles. This makes advanced writing assistance accessible for casual users while providing power features for heavy-duty professional needs.
