Show HN: A tool to help optimise your system prompt

I needed a way to choose between different system prompts for a ChatGPT-powered side project, so I built Prompt Picker.

The basic idea is: specify some candidate system prompts and a few example user inputs, and then run a blind experiment where you choose the better output from pairs of generations.

If you need to optimise the system prompt for your LLM-powered application, give it a try and let me know what you think.
