Prompy — Draft. Sharpen. Send.
Better prompts, fewer tokens — right where you type
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.
Hey Product Hunt 👋
I'm Arhaan, the maker of Prompy.
Like everyone here, I use ChatGPT, Claude, and Gemini every day. And I kept noticing the same thing: my first prompt was almost never my best one. I'd fire off something vague, get a mediocre answer, then spend three more rounds clarifying what I actually meant. That back-and-forth burns time and tokens.
So I built Prompy. It watches for a rough draft as you type, and quietly suggests a sharper, better-structured version right there in the box. One click to replace it. No new tab, no copy-paste, no "prompt engineering" homework.
The part I care about most: your keys never leave your device. Prompy has no backend and no account. You bring your own API key (Anthropic, OpenAI, Google, or Mistral), and your prompt goes straight to that provider — I never see it. Prefer zero cloud entirely? Point it at a local model via Ollama or LM Studio and nothing leaves your machine at all.
It's live on the Chrome Web Store and free to use:

I'd genuinely love your feedback.
Love how it works right inside the input box without any copy-paste hoops, and the option to keep keys local is a really thoughtful touch for folks who care about privacy.
The fact that keys never leave my device is huge, that alone had me try it. Works right inside ChatGPT without me copy pasting, which is way smoother than the prompt helpers I have used before.
honestly this looks super useful, but it would be great if it could remember the tone or style you prefer across sessions. like once you tweak the rewrite a few times, basically let it learn your voice so you don't have to keep adjusting every single time.
Ran it in ChatGPT for a few rough drafts and it caught the lazy assumptions I kept making. Nice that the key stays local too, that part matters to me.
honestly this looks pretty handy, especially the local mode angle. one thing i'd love is a way to save prompt templates or "personas" so you can reapply a specific tone or structure across different chats without rewriting it every time. basically like quick presets you can recall with a shortcut.
