Prompter turns the Claude Code or Codex setup you already have into a one-shortcut prompt rewriter for your Mac. Type a rough draft in any app, hit your shortcut, and a clearer prompt replaces your text in place. Polish keeps meaning, code, links and @mentions untouched. Expand builds a full brief and leaves [blanks] instead of guessing. No API key - rewrites run through your existing Claude Code or Codex login and count against your plan's normal limits. Free + open source (MIT), macOS 14+.
