An AI writing assistant should help with any text you find or write — not just content inside one app. PromptDC brings grammar fixes, rewrites, summaries, explanations, and tone changes to selected text across the web, from articles and blogs to email, social posts, AI chats, and Google Docs.
More than grammar
Beyond proofreading, PromptDC includes task-based profiles for email, social posts, summaries, replies, and professional tone, plus a Code profile for developers. Editable text is rewritten in place; results from read-only pages are copied to your clipboard.
Per-site profiles
Set a default writing profile per website so the right rewrite runs automatically — Grammar on Gmail, Social on LinkedIn — without choosing it every time.
Works in every text box and every other app
The PromptDC desktop app for macOS and Windows rewrites selected text in every text box, 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.
