Prompt Eval - Turn messy prompts into powerful AI instructions.

Prompt Eval helps you improve AI prompts before sending them. Paste a prompt to get structured feedback, improvement suggestions, and evaluation tags. Customize tag sensitivity to control how strictly prompts are analyzed. Quickly identify weak instructions, unclear goals, or missing context and turn rough ideas into clear, effective prompts for better AI results.

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 🙌
