System prompt generator: also inside Claude Code and Codex
PromptDC for Desktop turns a short brief into a structured system prompt in any macOS or Windows app, browser, IDE or terminal. Select your draft, press the global shortcut, review the editable role, rules, constraints and output format, then Replace or Copy.
You are a billing support assistant for a SaaS product. Role: answer questions about plans, invoices, refunds, and payment methods. Rules: only use the billing facts provided in context; never invent prices; if unsure, ask one clarifying question. Tone: concise, friendly, professional. Format: 2 to 4 sentences, then a bulleted next step. Refuse: legal, tax, or account-security actions, and escalate those to a human.

Works where you write
PromptDC rewrites selected text in any app, every browser, your IDE and your terminal on Mac and Windows.

Select text, press Cmd+Shift+E or Ctrl+Shift+E, review the result, then Replace or Copy. It never presses Enter for you.
Your profiles, your models
Pick a default profile per app, or bring your own API key on the Lifetime plan.

One desktop install works everywhere, including ChatGPT and Claude desktop, Cursor and VS Code chat panels, and Claude Code, Codex CLI, Gemini CLI and Grok in terminals. PromptDC is the first app that enhances coding prompts inside the terminal. The Chrome extension adds in-place rewriting and per-website profiles without Accessibility permission. Optional IDE extensions add a target-agent picker plus Simple or Structured output; the Code profile turns vague coding requests into implementation-ready prompts.
