Artis Mind - Prompt Optimizer: Build & test production-safe prompts (GPT, Claude, Gemini)

Hi Product Hunt, I’m a newly minted solopreneur, and this is one of my first products I’m launching publicly. Over the past year, I built several AI-based products - but I kept hitting the same wall. Getting the AI to respond the way I wanted always turned into a frustrating process of endless prompt tweaking, complex response parsing, and adding tons of security safeguards to prevent weird or unsafe outputs. I started wondering: what actually makes a good prompt? I read everything I could find - articles, threads, guides - but most advice was inconsistent or superficial. So I decided to dig deeper, analyze how my own prompts behaved, and experiment until I found what truly worked. That research led me to build ArtisMind - a tool that helps you engineer prompts, not just write them. It starts by generating clear requirements for your prompt (so the AI and you are aligned), then uses multiple AI models to iteratively build, test, and improve your prompt with real metrics and structure. You can even upload context files to guide results precisely. Most prompt tools focus on structure or quick generation - but I wanted something that actually ensures quality, security, and consistency across models. Now I use this tool daily to build new products, and it’s saving me hours of manual work while keeping my prompts production-ready. This project solves a real pain point I faced myself - and I hope it helps others struggling with the same thing. Would love your thoughts and feedback!
