I built this because I kept rewriting the same prompts across ChatGPT, Claude, and Cursor. None of them sync or talk to each other.
Promptzy stores everything as plain Markdown files on your Mac. Cmd+Shift+P from any app opens a Spotlight-style launcher, search, hit Enter, and the prompt auto-pastes anywhere. It also has global per-prompt keyboard shortcuts, to instantly insert your favorite prompt or skill directly into any app.
