Show HN: I built PrompTessor – a tool to help people write better AI prompts

https://promptessor.com/
12•rizkimurtadha•7mo ago
After countless hours of solo coding, designing, and iterating, I’m both excited and nervous to share my first-ever product: PrompTessor — now live.

As someone who constantly experiments with AI tools like ChatGPT and Midjourney, I often found myself stuck in a loop of trial-and-error. The issue wasn’t always the AI — it was often the prompt itself. That observation became the starting point for PrompTessor.

This tool doesn’t just optimize your prompt — it analyzes it. It gives you: - A prompt score - A breakdown of strengths and weaknesses - A fully optimized version of your prompt - And even a step-by-step guide on how to improve it

PrompTessor evaluates your input across six dimensions: Clarity, Specificity, Context, Goal, Structure, and Constraints — helping you communicate more effectively with any LLM.

It’s free to try, and my main goal right now is to gather as much real-world feedback as possible. As a solo founder, honest reactions and suggestions from this community would mean the world to me.

Try it here: https://promptessor.com

Every piece of feedback is incredibly valuable, and will help me shape PrompTessor into something truly useful.

Thanks for reading! Happy to answer any questions in the comments.
