Hi Alex — a quick note on the launch. I think we should push it a week and give the landing-page copy another pass before we ship. Let me know if that works.

PromptDC Desktop started with a simple frustration.

The browser extension could reach every text box on the web.

Mail, Slack, Notes, and your IDE lived somewhere else.

We wanted one shortcut for everything you type on the desktop.

A faster path from a rough thought to a clear email, reply, or prompt — without leaving the app you are already in.

Built to feel like the writing tool your Mac and PC should have had from the start.

Everything we can say for now

What is PromptDC Desktop?

PromptDC Desktop is a menu-bar writing assistant for macOS and Windows. Select text in any app, press the shortcut, and a native overlay rewrites it in place — emails, Slack messages, docs, and coding prompts included.

Is it available for both Windows and Mac?

Yes. There are installers for macOS (Apple Silicon and Intel) and Windows 10/11 (x64). Same account, same profiles, both platforms.

How does the global shortcut work?

Press ⌘⇧E on Mac or Ctrl+Shift+E on Windows in Mail, Slack, Notion, Cursor, VS Code, Discord, or any other app. PromptDC reads the selected text and opens a floating overlay next to your cursor. Replace pastes the rewrite back into the original field.

Does it follow Light Mode and Dark Mode?

Yes. The overlay and settings window follow your system appearance, or you can lock Light or Dark in preferences.

Can I use my own API keys?

Lifetime plans can bring their own keys for OpenAI, Anthropic, Gemini, DeepSeek, or a local Ollama instance. Keys stay on the machine and are sent only with each request.

Where does it work that the Chrome extension cannot?

Native apps. Mail, Slack, Notion, Discord, Notes, IDEs, and anything else on the desktop that is not a Chrome tab. The extension still covers the browser; Desktop covers the rest of the machine.
