I built Prompy with a simple mission: to help you draft, sharpen, and send better prompts flawlessly. But I know a tool is only as good as the workflow it actually fits into.
Prompy is an AI prompt optimizer for your browser and desktop. As you type in ChatGPT, Claude, Gemini and more, it rewrites your rough draft into a sharp, well-structured prompt. Bring your own key or run fully local — your keys never leave your device.
