Hey Product Hunt 👋 I built Prompt Eval because I kept running into the same problem: writing prompts for AI that should work, but produce inconsistent or weak results. Prompt Eval lets you paste a prompt and instantly get: • Structured feedback on what could be improved • Evaluation tags that highlight issues (clarity, context, constraints, etc.) • Adjustable tag sensitivity so you can run quick checks or stricter reviews The goal is simple: help people turn rough prompt ideas into clearer, more effective instructions before sending them to AI. I designed it to be lightweight and fast so it fits naturally into your workflow when working with LLMs. I’d really love feedback from the PH community: What tags would you want for prompt evaluation? What’s the hardest part of writing good prompts for you? Thanks for checking it out 🙌
