PromptDC is a profile-driven desktop writing and prompt app for macOS and Windows that works everywhere: any desktop app, every browser, IDE, and terminal. Select text, press Cmd+Shift+E or Ctrl+Shift+E, review the editable result, then Replace or Copy. Grammar, Email, Social, Summarize, Professional, Image Prompt, Reply, Concise, Explain, and Code profiles cover everyday writing and AI prompts.
Unlike writing assistants confined to supported sites, the PromptDC desktop app rewrites selected text in any app, every browser, IDE, and terminal on macOS and Windows. The optional Chrome extension adds in-place web rewriting and per-website profiles, while optional IDE extensions add focused editor AI chat workflows.
PromptDC's writing toolbar appears in any text box and beside any text you select on any website, with right-click access as well.
