What it does

PromptDC is a desktop app for macOS and Windows that rewrites selected text in any app, browser, IDE, or terminal. Press Cmd+Shift+E or Ctrl+Shift+E, review the editable rewrite, then replace or copy it. It handles grammar, emails, and social posts as well as coding prompts, with optional Chrome and IDE extensions.

PromptDC is a desktop app for macOS and Windows that rewrites text you select. You press Cmd+Shift+E or Ctrl+Shift+E, review the editable rewrite, then replace or copy it. The Code profile turns a vague request into an implementation-ready prompt, with Simple or Structured output in Regular, JSON, XML, or YAML format. Everyday writing profiles cover grammar, email, replies, social posts, summarizing, and explaining. The optional Chrome extension adds in-place web rewriting and per-website profiles, while optional IDE extensions add editor AI chat workflows. Pricing has three tiers: Pro at $9 per month, Enterprise at $15 per month, and a Lifetime option at $69. The Lifetime plan requires your own OpenAI, Claude, Gemini, or Grok API key, and you pay that provider directly for usage. Pro includes 200 prompt enhancements per month. The site does not state whether a free plan or trial exists, and it does not describe a public API.
