AI Email Writer Extension — Works in Every App and Browser

Turn a one-line note into a polished message with PromptDC, an AI email writer that works inside Gmail and most web inboxes. It structures your email with a greeting, a scannable body, and a polite close.

Keeps your facts

PromptDC preserves every name, date, and request you include and never invents commitments.

One tool, many tasks

The same extension also fixes grammar, rewrites for tone, and summarizes long threads.

Use PromptDC in email apps, every app and browser

The PromptDC desktop app for macOS and Windows rewrites selected text in email apps, 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.
