Carry the app brief beyond Devin.ai's browser

PromptDC for Chrome turns the app's screens, data rules, and edge cases into a clearer request inside Devin.ai. When you move to a CLI for migrations or tests, PromptDC Desktop rewrites the selected terminal input before execution.

From Devin.ai to the terminal, PromptDC works everywhere

The PromptDC desktop app for macOS and Windows enhances selected text in Devin.ai, every browser, IDE chat panel, desktop AI app and terminal. Use Cmd+Shift+E or Ctrl+Shift+E to open an editable review, then Replace or Copy.

PromptDC is the first desktop app to enhance prompts inside terminal CLIs, including Claude Code, Codex CLI, Gemini CLI, Grok, Agy and OpenCode. Choose the Code profile for implementation-ready prompts, and set it as the default profile for each coding app or terminal.

The Chrome extension and IDE extensions are optional. Chrome adds in-place rewriting without Accessibility permission, while IDE extensions add a target-agent picker and Simple or Structured output; the desktop app already covers browser fields, IDE chats and terminals.
