Hey!
We've been experimenting with the concept of automatically creating and ranking prompts since last weekend, and decided to open-source and pursue improvements in this project.
https://github.com/meistrari/prompts-royale
It's an application where you just state what you want the prompt to do, give it scenarios and expected outputs, and we generate prompts (or you can write your own) and make them battle! What you end up with is a rank of prompts, from best to worst and with their ratings.
You can try it out now on https://promptsroyale.com
Let me know what you think!
