PromptDC works right inside Gmail, so you can fix grammar, rewrite a rough draft into a professional email, or adjust tone before you hit send — without leaving your inbox.
From note to email
Type the gist and the Email profile structures it into a clear, professional message that keeps all your facts.
Beyond the inbox
The same extension follows you to LinkedIn, X, Google Docs, and AI chats.
A desktop writing app for Gmail and beyond
The PromptDC desktop app for macOS and Windows rewrites selected text in Gmail, every desktop app, browser and text field. Use Cmd+Shift+E or Ctrl+Shift+E to review an editable result, then Replace or Copy.
PromptDC is also the first desktop app to enhance prompts inside terminal CLIs, including Claude Code, Codex CLI, Gemini CLI, Grok, Agy and OpenCode. Select the Code profile for coding prompts, and choose a default profile for each application.
The Chrome and IDE extensions are optional additions. The browser add-on supports in-place rewriting without Accessibility permission and per-site defaults; editor add-ons provide a target-agent picker and Simple or Structured output, while the desktop app already works everywhere.
