A Windows app for writing better AI prompts. Score a prompt for clarity, ambiguity, and missing context, rewrite it with AI, keep every version, and paste your best prompts into any app with Ctrl+Shift+P. Works with OpenAI, Claude, Gemini, or Ollama.
Hey Product Hunt! 👋
I'm the maker of PromptNote.
I write a lot of prompts for ChatGPT, Claude, and Gemini, and I keep running into two problems:
1. My best prompts were scattered across notes, docs, and chat history.
2. I couldn't tell whether a prompt was actually good until I'd wasted a few runs on it.
So I built PromptNote, a desktop app that treats prompts like something worth crafting:
🎯 Evaluate: score any prompt on intent clarity, quality, ambiguity, context completeness, and answerability, with concrete suggestions to fix it.
✨ Improve: let AI rewrite the prompt, then compare the result with your original.
🕘 Versions: save every iteration, compare versions, mark one as "Production", and roll back at any time.
⚡ Quick picker: press Ctrl+Shift+P in any app to search and copy a prompt instantly.
🧩 Variables: {{placeholders}} for the parts that change
📁 Collections: Organize prompts, then import and export them to share with your team.
🔌 Bring your own model: OpenAI, Anthropic, Google Gemini, or a fully local Ollama model.
Your prompt library lives on your machine. Prompts only go to the provider you connect with, and only when you click Evaluate, Improve, or Run.
💰 Pricing: Try it free for 7 days, then it's a one-time $12 for lifetime access. No subscription. (You bring your own API key, or run a local model for free.)
Available now for Windows 10/11.
I'd love your feedback, especially: what would make you trust a prompt score? What should the evaluator measure next?
Thanks for checking it out! 🙏
